Question

what is water equivalent write its cgs unit ​

Answer 1

Determination of Water Equivalent of Calorimeter. In a reaction the quantity of heat that raises the temperature of some substance by some amount, the same quantity of heat can simultaneously raise the same temperature of a certain mass of water. The mass of water is then termed as water equivalent. cgs unit of water equivalent is kg/m per cube

Answer 2

Water equivalent can be described as the product of the mass of a body and its specific heat. Its C.G.S. unit is gram ($g$).

Explanation:

• Water equivalent is the amount of water required to consume the amount of heat equal to that which the substance consumes for the rise of one degree temperature.
• It is also expressed as equivalent to the product of the mass of the body and its specific heat.

        $\[Water\,equivalent = Mass \times Specific\,heat\]$

• Water equivalent can also be described as the mass of water whose heat capacity is equal to the heat capacity of a given body.
• It can be represented as:

       $\[Water\,equivalent = Heat\,capacity\]$

• The unit of water equivalent in S.I. unit is $\[kg\]$.
• Therefore, the unit of water equivalent in C.G.S unit is $g$.
