What is Heat? |
Heat is a form of energy, measured in joules |
|
|
What is temperature? |
Temperature is a measure of the average kinetic energy of particles. It is measured in degree Celsius. |
|
|
Absolute Zero |
There is a temperature where particles stop moving this is called Absolute Zero. Absolute Zero is -273°C |
|
|
What is Specific Heat Capacity? |
Specific heat capacity is the heat energy required to raise the temperature of 1 kg of a substance by 1°C |
|
|
What is Specific Heat Capacity measured in? |
J kg-1 °C-1 |
|
|
Formula for specific heat capacity |
Eh=c m Δt Eh = heat energy measured in joules (J) c = Specific heat capacity (J kg-1 °C-1) m = Mass (kg) Δt = Change in temperature (°C) (final - initial) |
|
|
What is Specific Latent Heat? |
The energy required to change a substances state, without change of temperature |
|
|
Formula for specific latent heat |
Eh=m l Eh = Energy taken in or given off (joules) m = mass (kg) l = specific latent heat of fusion/vaporisation (j/kg-1) |
|
|
Specific latent heat of fusion |
The heat energy required to turn 1 kg of a solid fully in to a liquid (melting). The heat energy given off when 1 kg of a liquid turns into a solid (freezing) Fusion = Liquid <-> Solid |
|
|
Specific latent heat of vaporisation |
The heat energy required to turn 1 kg of a liquid fully in to a gas (evaporation).The heat energy given off when 1 kg of a gas turns in to a liquid (condensation). Vaporisation = Liquid <-> Gas |
|
|
What is Pressure and the formula |
Pressure is the force per unit Area. Pressure is measured in pascals (Pa). P=F/A |
|
|
Kinetic theory of gases |
It states that all gases are made up of small particles moving around at high speed.These particles can collide with each other and the walls of their container. |
|
|
Boyles Law |
p1 V1= p2 V2 P1 = first pressure (Pa) P2 = second pressure (Pa) V1 = first volume (m^3) V2 = second volume (m^3) |
|
|
Gay-Lussac Law |
p1/T1 = p2/T2 P1 = first pressure (Pa) P2 = second pressure (Pa) T1 = first temperature (k) T2 = second temperature (k) |
|
|
Charles Law |
V1/T1 = V2/T2 V1 = first volume (m^3) V2 = second volume (m^3) T1 = first temperature (k) T2 = second temperature (k) |
|
|
General Gas Equation |
P1 x V1/T1 = P2 x V2/T2 |
