AQA A-Level
Physics Paper 2
, Internal Energy - CORRECT ANSWERS-The sum of the kinetic energy and the
potential energy.
Absolute Zero - CORRECT ANSWERS-0K, -273℃.
Temperature - CORRECT ANSWERS-The measure of the average kinetic energy of
the particles within a substance.
Kinetic Energy - CORRECT ANSWERS-E= 3/2 kT
Heat Transfer - CORRECT ANSWERS-The flow of thermal energy from higher
temperature to lower temperature.
Thermal Equilibrium - CORRECT ANSWERS-The average kinetic energy of the
particles in both are the same, meaning that they have the same temperature.
There will be a net flow of energy from hot to cold until the objects reach this.
Heating - CORRECT ANSWERS-Net flow of energy from hotter to colder object.
Doing Work - CORRECT ANSWERS-One body exerts a force on the other and causes
movement (energy transfer).
First Law of Thermodynamics - CORRECT ANSWERS-Energy can be transferred and
transformed, but it cannot be created or destroyed.
ΔU = ΔQ + ΔW - CORRECT ANSWERS-Change in Internal Energy = energy gained by
heating + energy lost by work done.
Specific Heat Capacity - CORRECT ANSWERS-the energy required to raise the
temperature of 1kg of a substance by 1℃.
Specific Heat Capacity Experiment - CORRECT ANSWERS-Immersion heater. Graph
of T against t. Rearrange IVt=mcT. Gradient can be used to calculate c.
Latent Heat - CORRECT ANSWERS-The heat energy needed to change the state pf a
substance at a constant temperature. Q = ml
Latent Heat of Fusion - CORRECT ANSWERS-Solid to Liquid
Latent Heat of Vaporisation - CORRECT ANSWERS-Liquid to Gas
What factors will affect the temperature change of a substance? - CORRECT
ANSWERS-• The amount of energy supplied.
• The substance.
• The mass of the substance.
