Question

Hot water bottles are used for fomentation. This shows that water

• A. has high heat losing ability and hence can be used as a heat reservoir
• B. has high specific heat capacity and hence can be used as a heat reservoir
• C. has high conducting ability and hence can be used as a heat reservoir
• D. has high heat gaining ability and hence can be used as a coolant

Answer 1

The correct option is B

has high specific heat capacity and hence can be used as a heat reservoir

Water has high specific heat capacity and hence once heated it will liberate large amount of heat while cooling and hence can be used as a heat reservoir
