Question
Two metallic blocks P and Q of masses in ratio 2: 1 are given the same amount of heat. If their temperature rise by the same amount, compare their specific heat capacities.
Advertisements
Solution
Let CP and Cq be the specific heat capacities of blocks P and Q respectively,
We know that,
`Q/(m xx Δt)`
`∴ (C_p/C_q) = ((Q / (2m xxΔt))/(Q / (m xx ΔT)) ) = 1/2`
Hence, the required ratio is 1: 2.
