Boyle's Law represents the relationship of volume as pressure is changed. The constants of Boyle's Law are temperature and number of molecules of gas

True.

Explanation:

Hello!

In this case, according to the ideal gas equation:

It turns out possible for us to obtain the Boyle's law, as a directly proportional relationship between pressure and volume, considering that both moles and temperature remain constant; in such a way, we write the following:

Therefore, for an initial (1) and final state (2) we are able to write:

Regards!

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
