Question

1.
The specific heat capacity of copper is 0.1 call g°C, find its value in
J/Kg.K.​

Answer 1

Answer:

The specific heat capacity of copper, S = 0.1 cal/g/°C

we have to find it in J/Kg/K

we know, 1 cal = 4.2 joule

1000g = 1 kg

change in degree Celsius = change in Kelvin

so, °C = K

now 0.1 cal/g/°C = 0.1 (4.2 J)/(10^-3 Kg)/K

= 0.1 × 4.2 × 10³/ J/Kg/K

= 0.42 × 10³ J/Kg/K
