By how much will the temperature of 2.00kg of air change if it absorbs all of the heat given up when 1.00kg of water cools from 40.degree to 20 degree?

Question

Thanks for all your help

Answer 1

q = 1,000g H2O x specific heat H2O x delta T
Solve for q and substitute for air as
q = 2000g air x specific heat air x delta T.
Solve for delta T.
