Which of the following substances has the maximum specific heat capacity?

$100 \ g$ of water is heated from $30^\circ C$ to $50^\circ C$. Ignoring the slight expansion of the water,the change in its internal energy is .......$kJ$ (specific heat of water is $4184 \ J/kg/K$):

The ratio of the heat capacities of two bodies is $1:4$. If the rate of heat loss is the same for both bodies under similar environmental conditions,then the ratio of the rate of fall of their temperatures is:

Is the specific heat of water greater than that of sand?

Define specific heat capacity and write its $SI$ unit.

The heat required to increase the temperature of a body by $1^{\circ}C$ is called........
