When two objects P and Q are supplied with the same quantity of heat, the temperature change in P is observed to be twice that of Q. The mass of P is half that of Q. The ratio of the specific heat capacity pf P to Q is
1:4
4:1
1:1
2:1
Correct answer is C
H = mcθ
HP = HQ, θP = 2θ,
mP = 12mQ
∴ HP = mQCPθP, also HQ = mQCQθQ
Since HP = HQ
∴ mPcPθP = mQcPθq
Putting in the conditions
12mQ × cP × 2θQ = mQ × θQ × cQ
∴ cP = cQ
CpCQ= 11
= 1:1
