Question

1.
The specific heat capacity of copper is 0.1 cal g-1 °C-1. Its value in JKg1 k-1
will be
1) 0.84 x 103 2) 0.42 x 103 3) 0.24 × 103 4) 4.2 103​

Answer 1

answer : option (2) 0.42 × 10³ J/Kg/K

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
