Read the given statements and select the correct option.
Statement 1: An iron ball at $35^{o} C$ is dropped in a mug containing water at $305.15 K$ . Then the heat will flow from the water to the iron ball.
Statement 2: In convection, heated molecules of a liquid themselves move to carry heat from the hot region to the cold region.

Both statement 1 and 2 are true and statement 2 is the correct explanation of statement 1
