Water boils at 120 °C in a pressure cooker. Explain the reason.
What are other units of heat? Name and define them.
1 kg of water freezes to form ice at 0°C. What amount of heat is withdrawn?
A piece of ice is heated at a constant rate. The variation of temperature with heat input is shown in the graph below:
(i) What are represented by AB and CD?
(ii) What conclusion can you draw regarding the 110°c nature of ice from the above graph?
A vessel of negligible heat*capacity contains 40g of ice in it at 0°C, 8g of steam at 100°C is passed into the ice to melt it. Find the final temperature of the contents of the vessel.
(Specific latent heat of vaporization of steam = 2268 J/g, specific latent heat of fusion of ice = 336 J/f and specific heat capacity of water = 4.2 J/g°C)
What is specific heat capacity?
The molar specific heats of an ideal gas at constant pressure and volume are denoted by Cp and Cv, respectively. If `gamma = "C"_"p"/"C"_"v"` and R is the universal gas constant, then Cv is equal to ______.
