What happens to the temperature of a 50g sample compared to a 100g sample when both receive 100 joules of energy?

• Both samples show identical temperature changes

• The 50g sample shows a larger temperature change

• The 100g sample shows a larger temperature change

• Temperature change is independent of mass

When measuring temperature changes in thermal energy transfer experiments, why is it important to use the same initial mass of materials?

• It makes the experiment look better

• It's not important as long as you use the same container

• To ensure fair comparison of energy transfer rates

• To make calculations easier for the teacher

In an experiment, equal masses of water and oil are heated with the same amount of energy. Why might they reach different final temperatures?

• Due to their different specific heat capacities

• Because of their different colors

• Due to their different prices

• Because of their different names
