Question

The diagrams show four blocks of steel. The blocks are all drawn to the same scale. The same quantity of thermal energy is given to each block. Which block shows the greatest rise in temperature?

Answer 1

Block 4 shows the greatest rise in temperature. The rise in the temperature is inversely proportional to the initial length. The concept of thermal expansion is used in the given problem.

What is thermal expansion?

Thermal expansion is the tendency of matter to alter its form, area, volume, and density in response to a change in temperature.

The formula for the thermal expansion is found as;

$\rm \triangle L = L \alpha \triangle T \\\\\ \triangle T = \frac{\triangle L}{L\alpha}$

The rise in the temperature is inversely proportional to the initial length;

Block 4 has the smallest initial length.

Hence, the block 4 has the greatest rise in temperature.
