# Thermal Equilibrium - Objective Question 1

Objective Question:
2 iron blocks, P and Q are in thermal contact. The initial temperature of P and Q are 10°C and 50°C respectively. Which of the followings is true when P and Q are at thermal equilibrium.

1. The temperature of P will be higher than the temperature of Q.
2. The net flow of heat between P and Q is zero
3. The temperature of P and Q will be lower than 50°C but higher than 10°C.
4. There is no heat flow between the 2 blocks.

The correct answer is II and III.
