The radiator of an engine is cooled by water because:

Write the old and new definition of calorie.

$A$ current-carrying wire heats a metal rod. The wire provides a constant power $(P)$ to the rod. The metal rod is enclosed in an insulated container. It is observed that the temperature $(T)$ in the metal rod changes with time $(t)$ as:
$T(t) = T_0(1 + \beta t^{1/4})$
where $\beta$ is a constant with appropriate dimensions,while $T_0$ is a constant with the dimension of temperature. The heat capacity of the metal is:

Why is water used in a rubber bag for fomentation on the body?

Why does the land in a desert get hotter during the day and colder at night quickly?
