Problem: How does the law of conservation of energy relate to energy exchanges between a thermodynamic system and its surroundings?a. In an energy exchange, energy can be transferred from the system to the surroundings, but not from the surroundings to the system.b. The law of conservation of energy doesn't tell us anything about energy exchanges between a thermodynamic system and its surroundings.c. In an energy exchange, energy can be transferred from the surroundings to the system, but not from the system to the surroundings.d. In an energy exchange, energy is transferred between the system and the surroundings. If the system loses energy, the surroundings gain energy, and vice versa.
