Question

of same 9.2 Two solid spheres A and B made material breit not different size Contains heat energy 100 J cand 20 J respectively. If they brought in contact what will be the direction of Theater transfer? Justify your answer ?​

Answer 1

Answer:

Due to the same material both spheres will have the same specific heat.

Thermal capacity = Mass x Specific heat

Thermal capacity of the first sphere: C

1

=m

1

S=4/3[π(r

1

)

3

ρS]

Thermal capacity of the second sphere: C

2

=m

2

S=4/3[π(r

2

3

ρS]

Thermal capacities are in the ratio of :

C

1

/C

2

=(r

)

3

/(r

2

)

3

=(1/2)

3

=1/8

So, the correct option is 1:8.
