Physics P1 mindmap (unfinished)

• 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.
• 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
• 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.
• 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
• It is measured in joules per kilogram degree Celsius and differs for different materials
• 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
• The equation for energy transfer by specific heat capacity (shc) is: energy transferred = mass x shc x temp. change.
