Quizplus · Accepted Answer

1) Energy is transferred from the hot iron to the colder water due to the process of heat transfer. Therefore, statement 1 is correct.
2) Thermal equilibrium is achieved when the temperature of the two objects is equal. Therefore, statement 2 is also correct.
3) There is no conversion of thermal energy from the iron to electrostatic energy in the water. Therefore, statement 3 is incorrect.
