Question 1

What is specific latent heat

Answer 1

Amount of energy needed to change 1kg of a substance without changing its temp

Question 2

What is the formula for constant

Answer 2

p V = Constant

Question 3

If the pressure is doubled what happens to the volume

Answer 3

Volume halves

Question 4

What causes the pressure of the gases

Answer 4

Gas particles colliding with walls of the container, these collision cause a force which acts at right angles to the walls of the container

Question 5

What is work

Answer 5

Transfer of energy by force

Question 6

What happens if we increase temp of gas particles

Answer 6

Increase kinetic energy as kinetic energy and temp of gas particles are related

Question 7

Why can bike pumps get warm

Answer 7

Because we are doing work on the gas increasing it’s internal energy
