Answer
Surface temperature of moon varies from $-190^\circ $ to $110^\circ $. Explanation: It is $110$ degree at day and minus $170$ at night. Moon doesn’t have an atmosphere & water vapour to diminish sun at day and retain heat at night. So either moon has $100 \%$ solar energy or completely lacks it.
