what is Specific heat capacity ?

The amount of energy needed to raise the temperature of a 1kg substance by 1 degree.

Or the energy released as a substance cools

New cards
2

Kinetic energy stores

The movement of energy of the particles

New cards
3

Temperature

Average internal energy of a substance (more energy higher temperature)

New cards
4

Internal energy

The total energy stored by the particles making up a substance or system

New cards
5

How much energy does 1kg of water need to increase the temp by 1 degree?

4200 J

New cards
6

What would happen if you did a SHC experiment in an open area?

Energy would be lost to surroundings (needs to be insulated or contained (lid))

New cards
7

How can you find the specific heat capacity of a substance?

Measure the mass, measure the temperature (turn on power), when the temp has increased stop experiment and record the energy on joulemeter, calculate SHC repeat to spot any anomalies

New cards
8

Specific latent heat capacity

The amount of energy required to change the state of 1kg of the substance with no temperature change.
