Select the best answer for the question.
12. The molecules in a material need to move with more energy for the material to change from a
A. gas to a solid.
B. liquid to a solid.
C. liquid to a gas.
D. gas to a liquid.
Answer (2)
The molecules in a liquid need to gain energy to change into a gas, which is the process of vaporization. This is the only option that requires an increase in energy compared to other state changes listed. Thus, the correct answer is C. ;
The molecules in a material need to gain energy to change from a liquid to a gas, which is the most energy-intensive transition among the options listed. Therefore, the correct answer is C. liquid to a gas.
