Latent and Specific Heat

It depends on the quantity of the substance

• Neither heat nor temperature

• Temperature

• Both heat and temperature

• Heat

It's the measure of hotness or coldness expressed in terms of any of several arbitrary scales.

• Heat

• Specific heat

• Latent heat

• Temperature

It's the SI unit for Heat

• Watts

• Celsius

• Joules

• Nm

It's the amount of heat required to change the state (gas,liquid, solid) of a unit of material

• Latent Heat

• Specific Heat

This symbol represents latent heat

• Q

• c

• ΔT

• L

This formula is used to find the amount of heat (energy) neccesary when there's a phase change

• Q= (h)(ΔT)

• Q=(m)(L)

• Q=(m)(c)(ΔT)

• Q=(k)(A)(dT)
