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
Homework Answers
Ans :
Heat is given as :
Heat = mass x specific heat x change in temperature
here mass is 10 g
specific heat = 0.031 cal/goC
change in temperature = 100oC - 0oC = 100oC
putting values :
= 10 g x 0.031 cal/goC x 100oC
= 31 cal
