Answer 1

Answer:

1 Cal okkkkkkkkkkkkkkkkkkkkkkkkkkkk okkkkkkkkkkkkkkkkkkkkkkkkkkkk okkkkkkkkkkkkkkkkkkkkkkkkkkkk okkkkkkkkkkkkkkkkkkkkkkkkkkkk you

Answer 2

Its value in JKg-1 K-1 will be :

• Given : The specific heat capacity of copper is 0.1 cal g^-1°C^-1

• Conversions given below :

1 calorie = 4.184 J

1 gram = 0.001 Kg

1 cal/ °C = 4.184 J/ K

• Substitute values in given data

0.1 cal g^-1 °C^-1

= 0.1×4.184/0.001 J Kg^-1 K^-1

= 4.184 J Kg^-1 K^-1

•Hence specific heat capacity of copper in J Kg^-1 K^-1 is 4.184.
