Paper 1
What I don't understand about my mistakes:
Section A
Q18) I thought energy is transfered through vibrations and not so much on density
Section B
Q6b) Is there a difference between good conductors of heat and good absorbers of radiation?
Section C
Q3b&c) I do not understand how a bet fit line is taken nor how you know which numbers to use to calculate the gradient
Things I realise:
Section A
Q11) I realised that when a car stops, kinetic energy doesn't just change to potential energy but heat energy is also a part of it to overcome friction.
What I learnt:
Section C
Q2c) I realised that energy does not always just contain kinetic energy or potential energy, but also other types like elastic energy and het energy
Paper 2
What I don't understand about my mitakes:
Section A
Q11) I thought that internal energy increases because of an increase in heat energy causing the molecules to vibrate, therefore increasing in speed and kinetic energy. Why was the answer about potential energy?
Section A
Q14) I thought black was a good absorber of heat and not an emitter of heat
Section A
Q15) Why does the temperature of water stop rising? I thought the temperature still rose but jist not as fast as before
Things I realise
Section A
Q20) I realised that kinetic energy is converted to heat energy to overcome friction and not potential energy..
