Answer:

Im not sure what you mean but I hope what I wrote helps you!

The Law of Conservation of Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another.

A chemist heats a fixed amount of gas in a sealed glass container. Which law is the chemist most likely investigating?

PilotLPTM [1.2K]

The law which this chemist is most likely investigating heating a fixed amount of gas in a sealed glass container is: Gay Lussac’s law.

Gay Lussac's law states that when the volume of an ideal amount of gas is held (kept) constant, the pressure of the gas is directly proportional to the absolute (Kelvin) temperature of the gas.

Mathematically, Gay Lussac's law is calculated by using the formula;

$PT = K\\\\\frac{P_1}{T_1} = \frac{P_2}{T_2}$

<u>Where:</u>

$P_1$ is the original pressure.

$P_2$ is the final pressure.

$T_1$ is the original temperature.

$T_2$ is the final temperature.

In conclusion, the chemist is most likely investigating how changes in temperature affect the pressure of the gas by heating a fixed amount in a sealed glass container in accordance with Gay Lussac's law.
