50 ~g of copper is heated to increase its temperature by 10^ C . If the same quantity of heat is given to 10 ~g of water, the rise in temperature is (specific heat of Cu =420 Jkg ⁻¹⁰ C ⁻¹ and specific heat of water is 4200 Jkg ⁻¹⁰ C ⁻¹ )

Options

  1. A6^ C
  2. B10^ C
  3. C5^ C
  4. D15^ C

Correct answer

C. 5^ C

Step-by-step solution

Given, Since, the same amount of heat supplied to copper and water Q₁=Q₂ m₁ s₁ t₁=m₂ s₂ t₂ Substituting the value, we get 50 420 10=10 4200 t₂ t₂=5^ C
