If water at $0\,^oC$ kept in a container with an open mouth, is placed in a large evacuated chamber,
All the water will vaporise
All the water will freeze
Part of the water will vaporise and rest will freeze
Ice, water and water vapour will be formed and reach equilibrium at triple point
Match the following according to conversion by heat :
Column $-I$ | Column $-II$ |
$(a)$ Required heat to convert solid into gaseous. | $(i)$ Latent heat of fusion |
$(b)$ Required heat to convert solid into liquid. | $(ii)$ Latent heat of vaporization. |
When $M_1$ gram of ice at $-10\,^oC$ (specific heat $= 0.5\, cal\, g^{-1}\,^oC^{-1}$) is added to $M_2$ gram of water at $50\,^oC$, finally no ice is left and the water is at $0\,^oC$. The value of latent heat of ice, in $cal\, g^{-1}$ is
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
A copper block of mass $2.5\; kg$ is heated in a furnace to a temperature of $500\,^{\circ} C$ and then placed on a large ice block. What is the maximum amount of ice (in $kg$) that can melt? (Specific heat of copper $=0.39\; J g ^{-1} K ^{-1}$ ;heat of fusion of water $=335\; J g ^{-1})$
Explain three states and change in states for matter.
