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
Kinetic energy stores
The movement of energy of the particles
Temperature
Average internal energy of a substance (more energy higher temperature)
Internal energy
The total energy stored by the particles making up a substance or system
How much energy does 1kg of water need to increase the temp by 1 degree?
4200 J
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))
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
Specific latent heat capacity
The amount of energy required to change the state of 1kg of the substance with no temperature change.
