They involve heat.
They involve heat.

They form new substances.
They form new substances.

I dont see that option here?

Answer 4

All of the given responses are correct. Chemical changes are different from physical changes because they involve the formation of new substances, whereas physical changes do not. Chemical changes may also be accompanied by shifts in the phase of matter and involve heating or release of energy. Physical changes, on the other hand, do not form new substances and are usually reversible.

Answer 5

The answer is that chemical changes and physical changes are different in several ways, as mentioned in the provided response. These differences include factors such as reversibility, the formation of new substances, phase changes, and heat involvement. To determine whether a change is chemical or physical, one can consider these characteristics.

Answer 6

Apologies for the confusion. The options provided in your original question were accurate. The correct answer based on those options is:

Chemical changes are different from physical changes because they form new substances.

Answer 7

I apologize for the oversight. You are correct, the option "Chemical changes form new substances" is not listed among the given options. I apologize for the confusion caused. The correct option from the given list is:

They form new substances.
