The correct options are A, D, and E. When two systems with differing temperatures come into contact, they strive for thermal equilibrium, reached when their temperatures equalize. Heat must be transferred from the warmer system to the cooler one. In this scenario, heat flows from the warm water to the vegetables, but the heat must first pass through the plastic bag, which facilitates that transfer. The water loses heat while the vegetables gain the same amount. As heat is absorbed, the kinetic energy of the vegetable molecules increases, making them vibrate faster, which raises the temperature. Consequently, the water's cooling down indicates it is losing heat.
