1. Define specific heat capacity (1)
The amount of energy required to raise the temperature of one kilogram of the substance by two degrees Celsius.
The amount of energy required to raise the temperature of one kilogram of the substance by one degree Celsius.
The amount of energy required to raise the temperature of one gram of the substance by one degree Celsius.
2. Give the equation that links s.h.c., mass, temperature and energy (1)
change in thermal energy = mass / specific heat capacity × temperature change
change in thermal energy = mass × specific heat capacity / temperature change
change in thermal energy = mass × specific heat capacity × temperature change
