The amount of heat required to raise the temperature of a body by $1^oC$ is called its

$A$ solid of $2 \,kg$ mass absorbs $50 \,kJ$ when its temperature is raised from $20^{\circ} C$ to $70^{\circ} C$. The specific heat capacity of this solid in units of $J / kg^{\circ} C$ is

Two spheres are made of the same material and have a diameter ratio of $1 : 2$. The ratio of their heat capacities is equal to ......

If the specific heat of a substance is infinite,it means

What is the value of the specific heat of water using the law of equipartition of energy?

$A$ heater supplying constant power $P$ watts is switched $ON$ at time $t=0$ to raise the temperature of a liquid kept in a calorimeter of negligible heat capacity. $A$ student records the temperature of the liquid $T(t)$ at equal time intervals. $A$ graph is plotted with $T(t)$ on the $Y$-axis versus $t$ on the $X$-axis. Assume that there is no heat loss to the surroundings during heating. Then,
