Sample questions

1. 1.The S.I. unit of specific heat capacity is
   • A.J kg⁻¹
   • B.J K⁻¹
   • C.J kg⁻¹ K⁻¹
   • D.kcal kg⁻¹ °C⁻¹
2. 2.The temperature of 600 g of cold water rose by 15°C when 300 g of hot water at 50°C was added to it. What was the initial temperature of cold water? (Specific heat capacity of water = 4.2 J/g°C).
3. 3.Why does the temperature recorded by a thermometer decrease when its bulb is covered with a piece of cloth soaked in spirit?
   • A.Spirit absorbs heat from the surroundings, cooling the bulb.
   • B.Spirit evaporates, absorbing latent heat from the bulb.
   • C.Spirit conducts heat away from the bulb rapidly.
   • D.Spirit lowers the atmospheric pressure around the bulb.
4. 4.Calculate the amount of ice which is required to cool $150 \mathrm{g}$ of water contained in a vessel of mass $100 \mathrm{g}$ at $30^{\circ}\mathrm{C}$, such that the final temperature of the mixture is $5^{\circ}\mathrm{C}$. (Take specific heat capacity of material of vessel as $0.4 \mathrm{J \, g^{-1} \, ^{\circ}C^{-1}}$, specific latent heat of fusion of ice $= 336 \mathrm{J \, g^{-1}}$, specific heat capacity of water $= 4.2 \mathrm{J \, g^{-1} \, ^{\circ}C^{-1}}$).
5. 5.A certain amount of heat Q warms 1 g of material X by 3°C and 1 g of material Y by 4°C. Which material has a higher specific heat capacity?
   • A.Material Y, because it shows a larger temperature change.
   • B.Material X, because it shows a smaller temperature change.
   • C.Both have the same specific heat capacity.
   • D.Cannot be determined without knowing Q.
