What is specific heat capacity?

Energy required to raise temp of 1 kg by 1°C

Specific heat capacity measures what?

Energy needed to change temperature of a substance

What is specific latent heat?

Energy required to change state of 1 kg without temp change

Temperature during latent heat

Remains constant

Energy use in specific heat capacity

Temperature change

Energy use in specific latent heat

State change

Specific heat capacity formula

ΔE=mcΔθ\Delta E = mc\Delta\theta

Specific latent heat formula

E=mLE = mL

What happens to bonds during latent heat?

They break or form between particles

Examples of state changes

Solid to liquid, liquid to gas
