Thermal energy

Define latent heat of fusion

Latent heat of fusion is the amount of energy needed to change phase from solid to liquid without a change in temperature

Define latent heat of vaporisation

Latent heat of vaporisation is the amount of energy needed to change phase from liquid to gas without a change in temperature.

Formula for power

p = e/t

Formula for energy

e = p x t

How to convert seconds to hours

How do you calculate velocity

square root 2ke/m

What is power and what is it measured in?

Power is the rate at which work is done or energy is transformed, measured in Watts (W)

When do you use Q=mcΔt?

Q=mcΔt is used when the problem provides an initial and final temperature.

When do you use Q=mL

This formula is used when a change in temperature isn’t provided.
