Temperature Change in Different Materials
Michelle set up a science investigation to explore temperature change in objects made of different materials. She heated the four objects listed in the table below to the same temperature (100°C). Michelle recorded which material heated to 100°C first, second, third, and fourth (last).

Multiple Choice Question
Next, Michelle wants to investigate the time it will take for iron to heat to 100°C when the mass is increased from 1 kg to 1.5 kg. Which statement best compares the energy required to heat the 1 kg and 1.5 kg samples of iron to 100°C?
A.
Less energy will be needed to heat the 1.5 kg sample of iron to 100°C because this sample has fewer molecules to move than the 1 kg sample.
B.
Less energy will be needed to heat the 1.5 kg sample of iron to 100°C because this sample has more molecules to move than the 1 kg sample.
C.
More energy will be needed to heat the 1.5 kg sample of iron to 100°C because this sample has fewer molecules to move than the 1 kg sample.
D.
More energy will be needed to heat the 1.5 kg sample of iron to 100°C because this sample has more molecules to move than the 1 kg sample.

The correct answer is:
**D. More energy will be needed to heat the 1.5 kg sample of iron to 100°C because this sample has more molecules to move than the 1 kg sample.**
This is because a greater mass means more molecules, which requires more energy to increase the temperature to the desired level.
**D. More energy will be needed to heat the 1.5 kg sample of iron to 100°C because this sample has more molecules to move than the 1 kg sample.**
