Two liquids X and Y having the same mass are supplied with the same quantity of heat. If the temperature rise in X is twice that of Y, the ratio of specific heat capacity of X to that of Y is
- A. 2:1
- B. 1:2Correct
- C. 4:1
- D. 1:4
Explanation
Since mass and heat supplied are the same, CΔθ is constant, i.e. C1Δθ1 = C2Δθ2. Since Δθx=2Δθy, C1×2Δθy=C2Δθy, so C1:C2 = 1:2.
