A steel ball of mass $0.1 kg$ falls freely from a height of $10 m$ and bounces to a height of $5.4m$ from the ground. If the dissipated energy in this process is absorbed by the ball, the rise in its temperature is ........... $^\circ \mathrm{C}$ (Specific heat of steel $ = 460\,Joule - k{g^{ - 1}}^\circ {C^{ - 1}},\;g = 10\,m{s^{ - 2}}$)

Maximum density of $H_2O$ is at temperature

Steam at $100\,^oC$ is passed into $22\,g$ of water at $20\,^oC$  The mass of water that will be present when the water acquires a temperature of $90\,^oC$  (Latent heat of steam is $540\,cal/g$) is ......... $\mathrm{g}$

The portion $AB$ of the indicator diagram representing the state of matter denotes

Steam at $100\,^oC$ is passed into $1.1\,kg$ of water contained in calorimeter of water equivalent $0.02\ kg$ at $15\,^oC$ till the temperature of the calorimeter rises to $80\,^oC$. The mass of steam condensed in kilogram is

Steam at $100\,^oC$ is passed into $22\,g$ of water at $20\,^oC$. The mass of water that will be present when the water acquires a temperature of $90\,^oC$ (Latent heat of steam is $540\, cal/g$ ) is ............ $\mathrm{g}$
