If 650 J of heat are added to 21 moles of a monatomic gas at constant pressure, how much does the temperature of the gas increase? (in Kelvins)
U = nRT
The Attempt at a Solution
well how do you even know how much the temperature changes by if they dont give u an initial temperature? or is it just as simple as solving for delta T in which you just do
650J = (5/2)(21)( 8.31 J/mol.K )(Delta T)
is it really that simple or do i have to do something with the 21 moles and convert it or anything? and once i do get the Delta T must that be converted or something in order to have it end up in Kelvins? I ended up with 1.4899K im not sure if that's right though.
