1)
Heat possessed by a body depends upon
Change in temperature
All of these
Given substance
Mass
2)
Specific heat of a substance depends upon
Volume of substance
Temperature of substance
Nature of substance
Mass of substance
3)
Requirement for heat to flow from one part of a solid to another
Density gradient
Uniform temperature
Uniform density
Temperature gradient
4)
What is meant by infinite heat capacity?
No heat is given out
No change in temperature whether heat is taken in or given out
All of these
No heat is absorbed
5)
Calorimeters are made of which of the following
Metal
Glass
Wood
Rubber
6)
The bomb calorimeter is used to measure heat of a reaction at fixed
Volume
Entropy
Pressure
Temperature
7)
Choose the wrong statement.
At constant pressure, heat added to the system increases the volume and raises the temperature
At constant volume, heat added to the system is used to raise the temperature of the system
Specific heat capacity at constant volume is less than specific heat capacity at constant pressure
At constant pressure, heat added to the system does no work
8)
Heat given to a body during melting is utilised in
Increasing the average distance between molecules
Increasing temperature
Decreasing the mass of the body
Increasing the density
9)
The temperature of a mixture
Can never be less than temperature of hotter body
Can be more than temperature of hotter body
Is always less than temperature of colder body
Is more than temperature of colder body
10)
Water is used as heating or cooling agent because
It has high specific heat capacity and absorbs more heat
It has low 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
