What is the difference between a cup of tea at 95°C, and a drop of tea at 95°C?

Answers

Answer 1

Answer:

See the explanation below

Explanation:

Both the cup of coffee and drop of coffee have the Same temperature of 95°C.

Although the difference is the cup of coffee has more heat contained in it than the drop of coffee. An explanation is when we heat a cup of coffee it will take more time to Attain in 95°C while the drop of coffee will take less time

A gas made up of homonuclear diatomic molecules escapes through a pinhole 3.98 times as fast as oxygen gas. Write the Chemical formula of the gas.

Answers

Answer:

H₂

Explanation:

To solve this question we must find, as first, find the molar mass of the homonuclear diatomic gas using Graham's law. With the molar mass we can identify this gas

Graham's law:

[tex]\frac{V_a}{V_b} =\sqrt{\frac{m_B}{m_A} }[/tex]

Where V is the speed of the gases and m the molar mass of those:

As Va is 3.98 times Vb (And mB is molar mass of oxygen gas = 32g/mol)

[tex]3.98 =\sqrt{\frac{32g/mol}{m_A} }[/tex]

15.84 = 32g/mol / mA

mA = 2.02g/mol

As is a homonuclear diatomic gas, the molar mass of the atom is 1.01g/mol. Thus, the gas is:

H₂

A 1.0 liter flask contains 90.1 moles of water vapor at 27.0 oC. What is the pressure of the gas?

Answers

Answer:

The pressure of the gas is 224839.8 atm

Explanation:

As we know

PV = nRT

Substituting the given values, we get -

P * 1 L = 90.1 moles * 8.314 4621(75). J K−1 mol−1 * 300

P = 224839.8 atm

The pressure of the gas is 224839.8 atm

How many kJ are needed to heat 300.0 g of ice at -5.00°C into steam at 100.°C?

Answers

Answer:

Q = 63.9 kJ

Explanation:

Given that,

Mass of ice, m = 300 g

We need to find the heat needed to heat the given amount of ice at -5.00°C into steam at 100.°C

The specific heat of ice, c = 2.03 J/g °C

The formula for heat needed is given by :

[tex]Q=mc\Delta T\\\\Q=300\times 2.03\times (100-(-5))\\\\Q=63945\ J\\\\Q=63.9\ kJ[/tex]

So, 63.9 kJ of heat is needed.

The substances which are generally used to generate heat and light energy on burning are called fuels. The diesel fuel contains the largest molecules. Thus option A is correct.

What is Diesel?

The diesel fuel which is also called the diesel oil is found to be a combustible liquid and it is produced from the fractions of crude oil. The diesel fuel is found to be less volatile than the gasoline.

The chemical composition of a diesel fuel is usually denoted as C₁₂H₂₄. Apart from the carbon and hydrogen atoms small amounts of 'S', 'N' and 'O' are also present in the diesel.

Here gasoline is a derivative product obtained by the fractional distillation of crude oil and it is generally used in passenger vehicles whereas kerosene is a highly flammable liquid obtained from the distillation of petrol and is less volatile than gasoline.

The gasoline contains only 4 to 12 'C' atoms per molecule and it is a lightweight hydrocarbon mixture. The number of 'C' atoms in kerosene ranges from 10 to 16 per molecule and the diesel fuel is known as the heavyweight hydrocarbon mixture with 8 to 21 'C' atoms per molecule.

Thus diesel fuel consists of larger hydrocarbon molecules than gasoline and kerosene.

Thus the correct option is A - Diesel.

Bobby has a toy car that is sitting at rest on the floor. He decides to play with his toy car and pushes it with 3 newtons to the right. Bobby's friend Sam also decides to play with the toy car and pushes it with 6 newtons to the left at the exact same time. Which of the following best describes the resulting motion of the toy car? A It travels to the right at an increasing speed. B It travels to the right at a constant speed. C It travels to the left at an increasing speed. D It travels to the left at a constant speed.

Answers

Answer: D

Explanation:

The car will move to the left because Sam is implying a grater force (3 N < 6 N) but it is traveling at a constant speed because there is still a force being acted upon it. <3

The result of applying forces to a toy car is required.

Option D is correct.

Force applied by Bobby is 3 N to the right

Force applied by Sam is 6 N to the left

Right is taken as positive and left is taken as negative.

m = Mass of toy

a = Acceleration

Net force applied to the toy

[tex]F=3-6\\\Rightarrow F=-3\ \text{N}\\\Rightarrow ma=-3\\\Rightarrow a=\dfrac{-3}{m}[/tex]

So, the toy will move left with a constant acceleration.

Constant acceleration means its speed will be increasing.

So, option D is correct.

What effect does an increase in carbon dioxide (CO 2 ) have on the concentration of hydrogen ions (H^ + ) in the blood?

Answers

Answer:

As the level of carbon dioxide in the blood increases, more H+ is produced and the pH decreases. This increase in carbon dioxide and subsequent decrease in pH reduce the affinity of hemoglobin for oxygen. The oxygen dissociates from the Hb molecule, shifting the oxygen dissociation curve to the right.

Make up a short story to explain jays speed and acceleration change throughout his walk. Make sure to address parts A-D

Answers

Answer:

Speed of jays increases first, again increases, decreases and then increases.

Explanation:

The speed of jays increases while moving from rest to point A and no acceleration due to constant speed. From point A to point B, the speed is continues to increase and no acceleration. From point B to point C, the speed of jays decreases and acceleration is produced in the journey due to change of speed and from point C to point D, the speed of jays again increases and acceleration is produced due to increasing the speed.

Answer:

The speed of jay's walk increases first, again increases, then it decreases and then increases due to his acceleration walk during parts A-D.
