The diagram shows the setup for an experiment involving a 1000 mL beaker, filled with 500 mL of water, sitting on a burner.
Which best describes the molecular motion of the water particles as the burner supplies heat?
A
The molecular motion will increase as less thermal energy is absorbed.
B
The molecular motion will decrease as less thermal energy is absorbed.
C
The molecular motion will increase as more thermal energy is absorbed.
D
The molecular motion will decrease as more thermal energy is absorbed.
C
The molecular motion will increase as more thermal energy is absorbed.
C
The molecular motion will increase as more thermal energy is absorbed.
To determine the best answer, let's assess the situation.
When the burner supplies heat to the water in the beaker, the water molecules will gain thermal energy. This increase in thermal energy will cause the water molecules to move faster and increase their kinetic energy.
Based on this information, the correct answer is option C:
C) The molecular motion will increase as more thermal energy is absorbed.
Therefore, as more thermal energy is absorbed from the burner, the molecular motion of the water particles will increase.
