Solution

The correct option is A True
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat. The relationship does not apply if a phase change is encountered, because the heat added or removed during a phase change does not change the temperature.

The specific heat of water is $1 c a l o r i e / g r a m ° C = 4.186 j o u l e / g r a m ° C$
