easy

If temperature scale is changed from $°C$ to $°F$, the numerical value of specific heat will

A

Increases

B

Decreased

C

Remains unchanged

D

None of the above

Solution

(b) $Q = m.c.\Delta \theta $ $\Rightarrow$ $c = \frac{Q}{{m.\Delta \theta }}$

In temperature measurement scale $\theta ^\circ F > \theta ^\circ C$ so ${(c)_{^\circ F}} < {(c)_{^\circ C}}$.

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 :

$T ( t )= T _0\left(1+\beta t ^{1 / 4}\right)$

where $\beta$ is a constant with appropriate dimension while $T _0$ is a constant with dimension of temperature.

The heat capacity of the metal is :
