1000 cm³ of air at 20 °C and 101.35 kPa is heated at constant pressure until its volume doubles. a) Use the ideal gas equation to calculate the final temperature of the gas.​

Answers

Answer 1

From Charles's law, the magnitude of the final temperature is 586 K

What is an Ideal Gas ?

An Ideal gas is a gas which obeys ideal gas equation at all pressures, volumes and temperatures. The ideal gas equation can be express as

PV = nRT

Where

P = pressureV = volumen = number of moleR = universal molar gas constantT = Temperature

Given that 1000 cm³ of air at 20 °C and 101.35 kPa is heated at constant pressure until its volume doubles.

From the ideal gas equation,

P1 = P2 = 101.35 kPaV1 = 1000 cm³V2 = 2000 cm³T1 = 20 + 273 = 293 KT2 = ?

To calculate the final temperature of the gas, we will use the formula below

V1/T1 = V2/T2

Since Pressure is constant

Substitute the necessary parameters into the formula

1000/293 = 2000/T2

Cross multiply

1000T2 = 586,000

T2 = 586,000/1000

T2 = 586 K

Therefore, the final temperature of the gas is 586 K

Explain the difference between Pavlov's classical Conditioning, and Skinner's Operant
Conditioning, give examples to illustrate how behavior can be learned according to each
one of those conditioning. Explain the example after explaining the process.

Answers

Skinner's Operant Conditioning focus stressed that the  consequences of a behavior will indicate if there is  possibility of it being repeated and also  the human behavior  can be attributed to something in a person's environment.

Pavlov's classical Conditioning stressed that two stimuli can be linked  together  so that there can be new learned response in indivisuals .

Example of Pavlov's classical Conditioning  is that a dogs could be conditioned to salivate at the sound of a bell if it was programmed to ring at the time of food.

Example of Skinner's Operant Conditioning is that of negative reinforcement which was demonstrated by placing a rat in  Skinner box  which then subjected to unpleasant electric current  and make it to experience some discomfort.

What is Classical conditioning?

Classical conditioning can as well be described as the Pavlovian or respondent conditioning which is the learning that do take place when two stimuli are linked together  and they can bring about new learned response in a person or animal.

Operant conditioning  was the one that stressed that the cause of human behavior  can be linked to the something in a person's environment.
