3. What do you notice about the temperature of the substance in the test tube after it is placed in the beaker of water? A)The temperature of the substance remains the same as it sits in the beaker of water.
B) The temperature of the substance decreases as it sits in the beaker of water.
C) The temperature of the substance increases as it sits in the beaker of water.

C: The temperature of the substance increases as it sits in the beaker of water

Explanation:

This question was taken from a video where an attempt was made to investigate the changes in temperature when a substance undergoes change from it's solid phase to its liquid phase.

To do this, as seen in the video online, it shows a solid substance in a test tube being placed in a beaker of water.

From observation, the water in the beaker has a warmer temperature than the solid substance present in the test tube and this in turn makes the test tube gradually increase in temperature.

Thus, the solid substance will as well increase increase in temperature when it is placed in the beaker of water.
