- Heating Houses
- Measuring Temperature
- When temperature increases, the kinetic energy of particles increase
- Temperature is arbitrary scale of hotness
- Heat= internal energy= absolute scale
- Thermogram uses colour to show temperature
- Specific Heat Capacity
- Measured in J/Kg*C
- SHC= energy needed to raise temperature of 1kg by 1*C
- Energy transferred= Mass x SHC x Temp. change
- When temperature of object rises, energy is transferred
- Specific Latent Heat
- When an object is heated and it changes state, energy is transferred, but the temp. remains constant
- Energy transferred= mass x SLH
- The energy needed to melt or boil 1Kg of a material (J/Kg)
- When a substance changes state, energy is needed to break the bonds instead of change the temp.
- Energy Flow
- Energy flows from hotter body to colder body
