1.Calculate the amount of ice that will separate out on cooling a vessel containing 150 g of water at 30°C and a 100 g copper vessel at the same temperature, to 5°C. (Specific latent heat of fusion of ice = 336 J g⁻¹, specific heat capacity of water = 4.2 J g⁻¹ °C⁻¹, specific heat capacity of copper = 0.4 J g⁻¹ °C⁻¹).
- A.30 g
- B.47 g
- C.60 g
- D.75 g
-
2.85 g of water at 30°C is cooled to 5°C by adding a certain mass of ice. Find the mass of ice required. Given: Specific heat capacity of water = 4.2 J/g°C; Specific latent heat of fusion of ice = 336 J/g.
-
3.50 g of a metal piece at 27°C requires 2400 J of heat energy to attain a temperature of 327°C. What is the specific heat capacity of the metal?
- A.0.08 J g⁻¹ °C⁻¹
- B.0.16 J g⁻¹ °C⁻¹
- C.0.32 J g⁻¹ °C⁻¹
- D.0.64 J g⁻¹ °C⁻¹

4.Assertion: The specific heat capacity of a substance is the amount of heat required to raise its temperature by $1^{\circ}\mathrm{C}$. Reason: The specific heat capacity of a substance is not its characteristic property. (a) Both assertion and reason are true and reason is the correct explanation of assertion. (b) Both assertion and reason are True and reason is not the correct explanation of assertion. (c) Assertion is false but reason is true. (d) Assertion is true but reason is false.
- a.Both assertion and reason are true and reason is the correct explanation of assertion.
- b.Both assertion and reason are True and reason is not the correct explanation of assertion.
- c.Assertion is false but reason is true.
- d.Assertion is true but reason is false.
-
5.A bucket contains 8 kg of water at 25°C. 2 kg of water at 80°C is poured into it. Neglecting the heat energy absorbed by the bucket, what is the final temperature of the water?
- A.30°C
- B.36°C
- C.45°C
- D.50°C
