Internal energy of the system changes by ΔE = 178 J.
Heat given to the system = Q = +658 J.
According to the first law of thermodynamics,
ΔE = Q + W
178 = 658 + W
∴ W = 178-658 = -480 J
Minus sign indicates that work is done by the system.
The answer is A
Explanation:
Vacuuming doesn’t involve a lot of physical movements.
Crystalline solids must have a specific, orderly arrangement of atoms to be considered so.
