Question

equal heat is given to two objects a and b of mass 1kg temperature of a is increase hg 50c which object has more specific heat and by what factor

Answer 1

SA=5/3 SB

Given that mass of A and B is equal and = 1g = mA = mB

Given change in temperature of A = ΔTA = 3°C

change in tem. of B = ΔTB = 5°C

Given that Equal amount of heat is applied to both

for A : Q = mAsAtA = 3SA    (i)

for B : Q = mBsBtB = 5SB     (ii)

When SA and SB are specific heat of A and B

From eq (i),(ii)

3 SA = 5 SB

SA = 5/3 SA
