JEE AdvancedPhysicsHeat and ThermodynamicsNumerical+4 / −1

The specific heat capacity of a substance is temperature dependent and is given by the formula

C=k T

, where

k

is a constant of suitable dimensions in SI units, and

T

is the absolute temperature. If the heat required to raise the temperature of

1 \mathrm{~kg}

of the substance from

-73^{\circ} \mathrm{C}

to

27^{\circ} \mathrm{C}

is

n k

, the value of

n

is

\underline{\hspace{2cm}}

. [Given:

0 \mathrm{~K}=-273{ }^{\circ} \mathrm{C}

.]
