A heating curve can be produced be heating a substance at a constant rate and measuring its temperature
What is A?
A is a solid being heated
What is B and C?
B is a solid melting and C is a liquid being heated
What is D?
D is a liquid boiling
What is E and F?
E and F is a gas being heated
A cooling curve can be used to determine the temperature at which changes of state occur
A cooling curve is produced by measuring the temperature of a substance as it cools and then plotting a graph of temperature against the amount of energy transferred
What is thermal energy?
The total energy of an object due to the kinetic energy of its molecules. Measured in Joules.
Describe temperature
The average kinetic energy of molecules. Measured in ˚C.
