Question

The thermal capacity of 10g body is 4 cal /°C. The specific heat of its material in J/kg-K
(A) 3360
(B) 1680
(C) 6330
(D) 1860​

Answer 1

Answer:

The thermal capacity of 10g of a substance is 8 cal/c

*given m=10g

*delta Q =8 cal/c

To convert 8 cal/c to j/kg

We should multiply 8 with 4.2÷10 to the power of -3

Then we will get on taking 10 power -3 to the numerator 10 power 3

So specific heat = delta Q÷ m

So specific heat = 8×4.2×10 to power of 3÷10

=8×4.2×100

=800×4.2

=800×42÷10

=80×42

=3360
