I don't need these solved I just need the steps to solve it and. what these problems in chemistry would be called so I can look up videos and extra work

The answers are as follows,

1. 4.71 L,

2. 3.29 L,

3. 1634.6 torr

Explanation:

All the above problems can be sorted out using the Boyle's law represents the relationship between the volume and pressure.

It can be expressed as follows,

                      P1V1 = P2V2

Rearranging the above expression, we get,

1) The first case can be solved as,

2) The second case can be solved as,

3) The third case can be solved as,

Thus the answers for all the three cases are found as,

1. 4.71 L,

2. 3.29 L,

3. 1634.6 torr respectively

i think it is true since you can test the answer and can use observations to complete it.
