Phys 4.2

Question 1

Celsius -> Kelvin

Answer 1

+273

Question 2

Boyle’s Law

Answer 2

The volume of a fixed mass of gas at constant temperature is inversely proportional to the pressure applied.

Question 3

Charles’ Law

Answer 3

The volume of a fixed mass of gas at constant pressure is directly proportional to the absolute temperature.

Question 4

Pressure Law / Guy-Lussac’s Law

Answer 4

The pressure of a fixed mass of gas at constant volume is directly proportional to its absolute temperature.

Question 5

Ideal Gas Assumptions

Answer 5

• Point molecules - Volume of space»_space; Volume of particles
• No intermolecular attractions - only collisions between the molecules and the sides of the container need to be considered
• Random motion - The average of many random collisions give smooth pressure
• Elastic collisions - The kinetic energy before collisions is equal to that after
• Impact time - Collision time «_space;Time between impacts

Question 6

Internal Energy of Ideal Gas

Answer 6

Only kinetic energy, no potential energy
Only translational kinetic energy, no rotational (monatomic)

Question 7

Specific Heat Capacity

Answer 7

The energy required to increase the temperature of unit mass by unit temperature without a change of state.
