Question

Part A

Calculate ΔE , if q= 0.761 kJ and w= -810 J .

Express your answer using two significant figures.

Part C

Calculate ΔE , if a system releases 66.4 kJ of heat to its surroundings while the surroundings do 43.0 kJ of work on the system. Using 2 sig figs.

Part E

Calculate ΔE , if the system absorbs 7.25 kJ of heat from the surroundings while its volume remains constant (assume that only P−V work can be done). Using 3 sig figs.
