Students take three samples of three different liquids, all at the same temperature, and place the samples into three identical beakers. They place all three beakers onto the same hot plate. Which of the following observations would support the idea that the amount of heat required to raise the temperature of matter, depends on the nature of the matter? Before heating, the initial masses of the three different liquids were slightly different.

After turning off the hot plates, all the liquids eventually returned to room temperature.

Some of the heat from the liquids was transferred to the air around the beakers.

After the same amount of time, the three samples were at different temperatures.
