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
