Question 1: State three factors which determine the quantity of heat energy in a body.
Question 2: Which substance has the highest specific heat capacity? How much is it?
Q1: a) Heat energy absorbed by a body is directly proportional to the rise in temp of a body.
b) Heat energy absorbed by a body is directly proportional to the mass of the body.
c) Heat energy absorbed by a body depends upon its nature and is commonly called specific heat capacity.
Q2: It has been found that water has the highest specific heat capacity, i.e., 4.2 J/g degree C or 4200 J/ kg degree C. No other substance in the world has such a high specific heat capacity and it has its natural consequences in sustaining life on the planet Earth.
