In supplying $400$ calories of heat to a system, the work done will be
$400$ joules
$1672$ joules
$1672$ watts
$1672$ ergs
(b) $W = JQ = 4.18 \times 400 = 1672\,joule$
What is heat capacity of a substance ?
A lead ball moving with a velocity $V$ strikes a wall and stops. If $50\%$ of its energy is converted into heat, then what will be the increase in temperature (Specific heat of lead is $S$)
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 $1 \ kg$ of the substance from $-73^{\circ} C$ to $27^{\circ} C$ is $n k$, the value of $n$ is. . . . . .[Given: $0 K =-273^{\circ} C$.]
