Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The greater the mass of a substance, ____
A
The greater is the amount of heat transferred.
B
The lesser is the amount of heat transferred.
C
The amount of heat transferred is not affected.
D
None of these.
Explanation: 

Detailed explanation-1: -(b) The amount of heat transferred is also directly proportional to the mass. To cause an equivalent temperature change in a doubled mass, you need to add twice the heat.

Detailed explanation-2: -The mass difference between two objects causes heat transfer. The density difference between two objects causes heat transfer. The temperature difference between two systems causes heat transfer. The pressure difference between two objects causes heat transfer.

Detailed explanation-3: -Indeed, the heat capacity of a given body is the greater, the greater the amount of substance contained in this body. For instance, the heat capacity of 10 kg of water is five times greater than the heat capacity of 2 kg of water. The heat capacity of a unit mass of substance is given the name of specific heat.

Detailed explanation-4: -Effect of mass on the thermal energy transfer-For instance when different masses of same objects are exposed to the heat transfer then the temperature change for both the masses will be different. And this is because large mass can absorb more heat and small mass can absorb less heat.
