Define water equivalent

Text Solution

Verified by Experts

The correct Answer is:
It is the quantity of water which would be raised through `1^(@)C` (or `1K)` by the amount of heat required to raise the temperature of the body through `1^(@)C` (or `1K)`. It is denoted by `W`, and is numerically equal to the product mass `(m)` of the body and its specific heat `(S)` divided by specific heat of water `(S_(w)), i.e., W = mS//S_(w)`.
