Question

equal heat is givqn to two object A and B of mass 1 g. temperatuer of A increases by 3 °c. and B by 5° c. whitch object has more specific heat? and by what factor?

Answer 1

Hey.

Here is the answer.

As, Q = m c ∆T

and as equal heat is given so for both the objects Q is same

∆T for A , ∆Ta = 3℃ & ∆T for B, ∆Tb = 5℃

so, for A , Q = 1g × c × 3℃ = 3c J

So, c of A = Q/3

and, for B, Q= 1g× c × 5℃ = 5c J

So, c of B = Q/5

Hence, c of A is more.

Also, Q/3 / Q/5 = 5/3

So, c of A is more by factor of 5/3 than B.

Thanks.
