Question

The thermal capacity of 10g of a substance is 8calories the specific heating j/kg k is

Answer 1

Specific heat capacity = Thermal capacity / Mass
= 8 cal/K / (10 g)
= 0.8 cal / (g K)
= 3347.2 J/(kg K)

Answer 2

Answer:

Explanation 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
