Question

if the specific heat of gold is 0.031 cal/g degree celsius, how many calories does it take to heat 10g gold from 0 degree celsius to 100 degree celsius

Answer 1

Ans :

Heat is given as :

Heat = mass x specific heat x change in temperature

here mass is 10 g

specific heat = 0.031 cal/g^oC

change in temperature = 100^oC - 0^oC = 100^oC

putting values :

= 10 g x 0.031 cal/g^oC x 100^oC

= 31 cal
