- Physics (P1)
- Heating Houses
- Measuring Temperature
- A thermogram uses colour to show temperature.
- Areas that are coldest are black/dark blue/purple.
- Areas that are hottest are white/yellow.
- Areas that are hottest are white/yellow.
- Areas that are coldest are black/dark blue/purple.
- Temperature is a measurement of hotness on an arbitrary scale
- When a temperature of a body increases, the average kinetic energy of the particles increases.
- Heat is a measurement of internal energy; it is measured on an absolute scale
- A thermogram uses colour to show temperature.
- Energy Flow
- Energy, in the form of heat, flows from a warmer to a colder body.
- When energy flows away from
- Energy, in the form of heat, flows from a warmer to a colder body.
- Specific Heat Capacity
- All substances have a property called specific heat capacity.
- It is the energy needed to raise the temperature of 1 kg by 1.C
- It is measured in joules per kilogram degree Celsius and differs for different materials
- The equation for energy transfer by specific heat capacity (shc) is: energy transferred = mass x shc x temp. change.
- All substances have a property called specific heat capacity.
- Specific Latent Heat
- It is measured in joules per kilogram (J/kg) and differs for different materials and each of the changes of state.
- Specific latent heat is the energy needed to melt/boil 1 kg of the material.
- The equation for energy transfer by specific latent heat (slh) is: energy transferred = mass x slh
