Question

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

Explanation:

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

Answer 2

Answer:

Answer

We know that Q=msdt

Q is 600 caloriee

M is 3 kg

dt is 10 degree

600cal=3×10×s×kgcelsius

s=20. Cal/kg celsius
