It would a a chemical change as you cant see the boiling points changing or being formed. Physical changes are only when you visibly and physically observe the change

What happens to an object as its thermal energy increases?
NemiM [27]

Answer:

It heats up.

Explanation:

Because thermal energy is based off the temperature of an object and the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increase.

If you have a block of plastic and a block of copper that are the same mass and are placed in the sun for 10 minutes. What is th
LuckyWell [14K]

INFORMATION:

Is given that:

- if you have a block of plastic and a block of copper that are the same mass and are placed in the sun for 10 minutes.

And after the 10 minutes copper has a higher temperature.

We must determine the reason.

STEP BY STEP EXPLANATION:

To determine it, we need to know the concept of specific heat

If the block of copper has a higher temperature after 10 minutes, that means copper needs less heat to raise its temperature.

So, plastic has a higher specific heat than metal, so it takes more energy to heat plastic than copper. As a result, plastic would heat up more slowly.

ANSWER:

The explanation for the copper having a higher temperature after 10 minutes in the sun, is that plastic has a higher specific heat than metal, so it takes more energy to heat plastic than copper. As a result, plastic would heat up more slowly. Since the copper has a lower specific heat, it will be heat quickly.
