Question

An iron ball and an aluminum ball of mass 100 g each are heated to the same temperature and then cooled to 20°C. The heat lost by the iron ball is 36 J, and the heat lost by the aluminum ball is 72 J. What can be concluded?

A) The specific heat of iron is greater.
B) The specific heat of aluminum is greater.
C) The iron ball was heated to a higher temperature.
D) The aluminum ball was heated to a higher temperature.

Answer 1

The specific heat of aluminum is greater.

Step-by-step explanation:

The heat lost by the iron ball is 36 J, and the heat lost by the aluminum ball is 72 J. From this information, we can conclude that option B) The specific heat of aluminum is greater. This is because the heat lost by the aluminum ball is twice as much as the heat lost by the iron ball, indicating that aluminum requires more heat energy to achieve the same temperature change as iron.
