	1)	Heat possessed by a body depends upon
		Mass Given substance Change in temperature All of these

	2)	Specific heat of a substance depends upon
		Mass of substance Temperature of substance Volume of substance Nature of substance

	3)	Requirement for heat to flow from one part of a solid to another
		Density gradient Uniform density Uniform temperature Temperature gradient

	4)	What is meant by infinite heat capacity?
		No heat is absorbed All of these No heat is given out No change in temperature whether heat is taken in or given out

	5)	Calorimeters are made of which of the following
		Metal Rubber Wood Glass

	6)	The bomb calorimeter is used to measure heat of a reaction at fixed
		Entropy Pressure Volume Temperature

	7)	Choose the wrong statement.
		Specific heat capacity at constant volume is less than specific heat capacity at constant pressure At constant pressure, heat added to the system increases the volume and raises the temperature At constant pressure, heat added to the system does no work At constant volume, heat added to the system is used to raise the temperature of the system

	8)	Heat given to a body during melting is utilised in
		Increasing the average distance between molecules Decreasing the mass of the body Increasing the density Increasing temperature

	9)	The temperature of a mixture
		Can be more than temperature of hotter body Is more than temperature of colder body Can never be less than temperature of hotter body Is always less than temperature of colder body

	10)	Water is used as heating or cooling agent because
		It has low specific heat capacity and absorbs more heat It has high specific heat capacity and absorbs more heat It has high specific heat capacity and absorbs less heat It has low specific heat capacity and absorbs less heat
