Read the following and then fill in the answers to the questions. Sensible heat is the heat gained or lost by a body resulting in a change in temperature. Latent heat or hidden heat is the heat gained or lost by a body during a change of state when it does not result in any change in temperature. Heat capacity or thermal capacity of a body is defined as the amount of heat required to raise its temperature by 1 o C. The SI unit of heat capacity is J/ o C (Joules per degree Celsius). Specific heat capacity of a substance is defined as the amount of heat required to raise the temperature of a unit mass of it by 1 o C. Therefore: Specific Heat capacity = Heat capacity/mass The SI unit of specific heat capacity is J/(kg o C). However, a commonly used unit is J/(g o C). Water has a specific heat capacity of about 4.2 J/(g o C), or 4200 J/(kg o C) in SI units. More accurately, the specific heat capacity of water is 4.184 J/(g o C) or 4184 J/(kg o C). The very high value for the specific heat capacity of water is responsible for land breezes,
