Heat totaling 2700.0 J leaves a glass of water at 75.0 C to bring it to room temperature (20.0 C). What is the mass of the water in g (ignore the glass)?

2700 = m *specific heat of water * (75-20)
so you find the specific heat of water, then multiply that times the change in temperature then divide that into the joules?
Yes
about 4180 Joules/ kg deg K
as I remember
about 4180 Joules/ kg deg K
as I remember
By the way change in degrees K is the same as change in degrees C
C = 273 + K
so delta C = delta K
C = 273 + K
so delta C = delta K
