Question

(Ans. 5.6 cm)
d. Two substances A and B have specific
heats c and 2 c respectively. If A and B
are given Q and 4Q amounts of heat
respectively, the change in their
temperatures is the same. If the mass of
A is m, what is the mass of B?​

Answer 1

Answer:

Before solving this question we all should know about this formula

∆T = Q/mc

where ∆T is change in temperature

and m is mass and c is specific heat

now in our question ∆T is same for both substances then

Q¹/m¹c¹=Q²/m²c²

Q/mc. =4Q/m²2c

m². =2m

so the mass of object B is 2m
