Heat is supplied to a certain homogenous sample of matter, at a uniform rate. Its temperature is plotted against time, as shown. Which of the following conclusions can be drawn
Its specific heat capacity is greater in the solid state than in the liquid state
Its specific heat capacity is greater in the liquid state than in the solid state
Its latent heat of vaporization is greater than its latent heat of fusion
Both $(b)$ and $(c)$
Write a latent heat unit and dimensional formula. On what does the value of latent heat depend ?
A closed bottle containing water at $30°C$ is carried to the moon in a space-ship. If it is placed on the surface of the moon, what will happen to the water as soon as the lid is opened
The figure given below shows the cooling curve of pure wax material after heating. It cools from $A$ to $B$ and solidifies along $BD$. If $L$ and $C$ are respective values of latent heat and the specific heat of the liquid wax, the ratio $L/C$ is
when a man eats $100\,g$ of ice in a minutes, how much power will he get ? The latent heat of ice is $80\,cal/g$.
What is latent heat of fusion ? What is latent heat of vapourization ? Give its value for water.
