Determine if each of the statements is True or False regarding the First Law of Thermodynamics.
1. If the system loses energy to the surroundings, the surroundings could also lose energy to the system.
2. If the system gains thermal energy from the surroundings, the temperature of the surroundings decreases.
3 If the system gains 25 kJ of energy from the surroundings without doing any work on the surroundings, the surroundings could lose 20 kJ of energy.
