Question

how much will the water temperature change if 4000.0j of energy is removed from a 50.0g sample of copper? Cu=0.385j/gc

Answer 1

Same equation as in last question:
\[\Large Q=m \times c \times \Delta T\]
Solve for the change in temperature:
\[\Large \Delta T=\frac{ Q }{ m \times c }\]
Plug in the data and evaluate.

Answer 2

thanks I got it.

Answer 3

No problem.
