the energy needed to melt the body without a change in temperature
the energy needed to raise the temperature of the body by one degree Celsius
the increase in the volume of the body when its temperature is raised by one degree Celsius
the total amount of internal energy in the body
The heat capacity of a substance depends on the followings, EXCEPT:
mass of substance.
type of substance.
Quantity of heat supplied.
ice point and steam point.
A metal has a specific heat capacity of 360 J / (kg 0C). An object made of this metal has a mass of 2.0 kg.
What is the thermal capacity (heat capacity) of the object?
180 J / 0C

Which one will have the SMALLEST change in temperature?
For a skillet, used for cooking, do you want a high or low specific heat capacity?
High, so that it will need more energy to heat up
Low, so that it will change temperature quickly
What is the temperature of the metal cube when thermal equilibrium is achieved between the cube and the liquid?
If 1 kg of water and 1 kg of paraffin are supplied with the same amount of heat, the temperature rise of the paraffin is about twice that of water. This is because
the freezing point of paraffin is less than that of water
the force of attraction between the molecules of paraffin is less than that of water
the specific heat capacity of paraffin is less than that of water
the specific latent heat of fusion of paraffin is less than that of water

specific heat capacity of 10 g copper block is lower than 100 g copper block
heat capacity of 10 g copper block is higher than 100 g copper block
specific heat capacity of 10 g copper block is higher than 100 g copper block
