Part 1. A glass bottle, which is half-filled with water, has a balloon attached to its
opening. The bottle is placed in a hot water bath for some time. Explain the change
to the size of the balloon based on the kinetic molecular theory.
Part 2. What would most likely happen to the balloon if the bottle was then placed
into a jar of cold water with ice cubes? Explain your answer based on the kinetic
molecular theory
In both cases, assume the balloon is attached tightly enough so that air does not
escape the system. (10 points)

Answers

Answer 1

Answer:

See explanation

Explanation:

According to the kinetic theory, a gas temperature is a measure of the average kinetic energy of the molecules of the gas. Thus, when the balloon is attached to the opening of a glass bottle placed in a hot water bath for some time, the molecules of the gas inside the balloon acquire greater kinetic energy and move faster. Hence, the molecules spread out and the gas expands - its size increases.

When the bottle is placed into a jar of cold water with ice cubes, the molecules of the gas loose energy and begin to coalesce. As a result of this, the volume of the gas decreases and the balloon shrinks. This is a demonstration of Charles law.

Answer 2

Answer:

According to the kinetic theory, a gas temperature is the measure of the average kinetic energy of the molecules of gas. Thus, when the balloon is attached to the opening of a glass bottle placed in a hot water bath for some time, the molecules of gas inside the balloon acquire greater kinetic energy thus moving faster. Hence, the molecules spread out and the gas expands thus expanding the balloon.

 When the bottle is placed in a cold jar of cold water with ice cubes, the molecules of the gas loose energy thus decreasing the speed of the molecules within the gas. As a result of this, the size of the balloon should begin to shrink and so does the volume of the gas. Therefore, innately showing a demonstration of Charles' law of gasses which is the law that the volume of gasses is proportional to the temperature, (if the volume increases so does the temperature and vice versa).

Answer:

Explanation:

air particles and odours move freely in all directions and eventually spreads out thus reaching the sitting room

The process of diffusion causes the particles of the aroma of the fried fish to reach the living room.

What is diffusion?

Diffusion can be described as the net movement of anything such as molcules, or energy from a region of higher concentration to a region of lower concentration. Diffusion is generally driven by a gradient in Gibbs free energy or chemical potential.

The concept of diffusion can be used in fields such as physics, chemistry, biology, sociology, economics, and finance. The central idea of diffusion is common that a substance undergoing diffusion spreads out from a point or location at which there is a higher concentration of that substance.

A gradient can be defined as the change in the value of an amount such as concentration, pressure, or temperature with a change in another variable, distance.

A change in concentration over a distance is known as a concentration gradient, and a change in pressure over a distance is known as a pressure gradient.

The Latin word diffusion means "to spread out." Therefore, the aroma of the fried fish diffuses and reaches to lining room.

Explain which intermolecular force is primarily responsible for the unusually high boiling point of H2OH2O. Compare the strengths of intermolecular forces of attraction present in a sample of liquid water to the strengths of intermolecular forces of attraction present in liquid samples of H2SH2S, H2SeH2Se, and H2TeH2Te. Justify your answer using the information presented in both tables, and complete the statements below.

Answers

Answer:

See explanation

Explanation:

Intermolecular forces are forces of attraction that exist between molecules of a substance in a particular state of matter.

The dominant intermolecular force of attraction in H2O is the hydrogen bond. The hydrogen bond exists between molecules of a substance when the substance is made of hydrogen atoms bonded to atoms of a highly electronegative element. Hence, strong hydrogen bonding accounts for the high boiling point of water.

The magnitude of hydrogen bonding between molecules depends on the electro negativity of the atoms to which hydrogen is bonded.

The more the electro negativity of the atoms to which hydrogen is bonded, the greater the magnitude of intermolecular hydrogen bonding.

Since the electro negativity of elements decrease down the group, the strength of intermolecular hydrogen bonding between the molecules decreases as follows;

H2O> H2S> H2Se> H2Te

Which of the following would increase the pressure of a gas in a container?
A. Decreasing the kinetic energy of the gas
B. Increasing the temperature of the gas
C. Decreasing the number of gas particles
D. Increasing the volume of the container

Answers

The only option that would increase the pressure of a gas in a container is B. Increasing the temperature of the gas. Option B

To understand which factor would increase the pressure of a gas in a container, we need to consider the relationship between pressure and various variables in the ideal gas law and the kinetic theory of gases.

The ideal gas law states that pressure (P) is directly proportional to the number of gas particles (n), the temperature (T), and inversely proportional to the volume (V) of the container. Mathematically, it can be expressed as:

PV = nRT

where R is the ideal gas constant.

Based on this equation, we can analyze the options given:

A. Decreasing the kinetic energy of the gas: According to the ideal gas law, temperature is directly proportional to pressure. Therefore, decreasing the kinetic energy (which is related to temperature) would decrease the pressure, not increase it.

B. Increasing the temperature of the gas: As mentioned above, temperature is directly proportional to pressure. Increasing the temperature of the gas would increase its kinetic energy, resulting in more frequent and energetic collisions with the container walls, thus increasing the pressure.

C. Decreasing the number of gas particles: According to the ideal gas law, the number of gas particles (n) is directly proportional to pressure. Therefore, decreasing the number of gas particles would decrease the pressure, not increase it.

D. Increasing the volume of the container: According to the ideal gas law, volume (V) is inversely proportional to pressure. Increasing the volume of the container would decrease the pressure, not increase it.

c. The reaction Br2 (l) --> Br2 (g) has ΔH = 30.91 kJ/mol and ΔS = 93.3 J/mol·K. Use this information to show (within close agreement) that the boiling point of bromine is 332 K.

Answers

The boiling temperature of bromine is 331.29 K

Explanation:

From the question given above, the following data were obtained:

Br₂ (l) —> Br₂(g)

Enthalpy change (ΔH) = 30.91 KJ/mol

Entropy change (ΔS) = 93.3 J/mol·K

Boiling temperature (T) =?

Next, we shall convert 30.91 KJ/mol to J/mol. This can be obtained as follow:

1 KJ/mol = 1000 J/mol

Therefore,

30.91 KJ/mol = 30.91 × 1000

30.91 KJ/mol = 30910 J/mol

Thus, 30.91 KJ/mol is equivalent to 30910 J/mol.

Finally, we shall determine the boiling temperature of bromine. This can be obtained as follow:

Enthalpy change (ΔH) = 30910 J/mol

Entropy change (ΔS) = 93.3 J/mol·K

Boiling temperature (T) =?

ΔS = ΔH / T

93.3 = 30910 / T

Cross multiply

93.3 × T = 30910

Divide both side by 93.3

T = 30910 / 93.3

T = 331.29 K

Thus, the boiling temperature of bromine is 331.29 K
