Ice is given thermal energy and begins to melt while remaining at the same temperature. Which changes happen to the molecules of water? (1 point)
A. The molecules will have more potential energy because of their arrangement.
B. The molecules will have a greater average kinetic energy because of their movement.
C. The molecules will have more potential energy because of their movement.
D. The molecules will have a greater average kinetic energy because of their arrangement.
Please answer ASAP!
When ice or any other solid melts, its potential energy increases. Indeed, this is the only increase in energy, since the thermal kinetic energy, or temperature, does not increase while melting. Potential energy is the latent energy that could be released by the water, and this increases because the water will release heat energy if it is frozen solid again.
What does that tell you?
It's potential energy because of the molecules' arrangement? Right?
the molecules will have more potential energy because of their arrangement.
Well, well, well, it seems we have some molecules in a bit of a state, don't we? When ice is given thermal energy and starts to melt while remaining at the same temperature, a few interesting changes take place. Let's dive into the options, shall we?
A. The molecules will have more potential energy because of their arrangement.
Oh, those sneaky little molecules, always rearranging themselves. But in this case, the arrangement of the water molecules doesn't affect their potential energy.
B. The molecules will have a greater average kinetic energy because of their movement.
Ah, kinetic energy, the energy of motion. As the ice melts, the water molecules start jiggling and wiggling around a bit more, so their average kinetic energy does increase. Good guess, my friend!
C. The molecules will have more potential energy because of their movement.
While the water molecules do gain some energy due to their increased movement, it's not in the form of potential energy. So, we can rule out this option.
D. The molecules will have a greater average kinetic energy because of their arrangement.
Arrangement? Kinetic energy? Nah, those two don't mix very well. The arrangement of the molecules doesn't really affect their kinetic energy in this case. So, let's move on from this one.
So, my dear friend, the correct answer is B. The molecules will have a greater average kinetic energy because of their movement.
Hope that puts a smile on your face!
When ice is given thermal energy and begins to melt, the temperature of the ice remains constant until all the ice has melted. The changes that happen to the molecules of water in this process are as follows:
B. The molecules will have a greater average kinetic energy because of their movement.
At a molecular level, the thermal energy causes the water molecules to vibrate and move faster, leading to an increase in their kinetic energy. This increase in kinetic energy is reflected in the movement of the water molecules. However, since the temperature remains constant, the average kinetic energy of the molecules also remains constant.
A. The molecules will have more potential energy because of their arrangement.
In this scenario, the arrangement of the water molecules does not change significantly. The potential energy of the water molecules is primarily influenced by intermolecular forces, such as hydrogen bonding. As long as the temperature of the system remains constant, the potential energy due to molecular arrangement will not change significantly.
Therefore, the correct answer is B. The molecules will have a greater average kinetic energy because of their movement.
