HELP with physics homework, thermal energy?
I cannot figure out how to solve this problem, can someone show me how?
A small engine pumps 100 liters of water from a well 300m deep. What would the change in temperature be for the engine 20 liter cooling system (filled with methanol) if the engines efficiency is 54%
Specific heat of water 4180, and of methanol 2450
density of water 1kg= L
