Specific Latent Heat

Question 1

Specific Latent Heat is…

Answer 1

The energy required for a substance to undergo a change of state without a change in temperature

Question 2

What is Specific Heat Capacity?

Answer 2

The energy required to raise the temperature of 1kg of mass by 1 Degree

Question 3

When using a blender to make potato soup, why is a jug with a low thermal conductivity useful?

Answer 3

To ensure less heat from the soup is dissipated/lost so the soup stays hot.

Question 4

Explain why Gaseous water at 100Celcius contains more energy than liquid water at 100Celcius

Answer 4

More energy is required to change the state of water, to overcome the particle bonds

Question 5

Specific Latent Heat Equation

Answer 5

Energy = Mass x Specific Latent Heat

Question 6

Specific Heat Capacity Equation

Answer 6

Change in energy = mass x specific heat capacity x change in temperature

Question 7

Current Equation

Answer 7

I = Square root of Power/Resistance
