The new pressure is 81.675 torr
Since temperature and moles are held constant, we use Boyle's Law:
A gas law known as Boyle's law asserts that a gas's pressure is inversely proportional to its volume when it is held at a fixed temperature and of a given mass.
To put it another way, as long as the temperature and volume of the gas remain constant, the pressure and volume of the gas are inversely proportional to one another.
The Anglo-Irish chemist Robert Boyle proposed Boyle's law in the year 1662.
P1V1=P2V2. Simply plug in your values. The units can remain in torr. Converting to atmospheres is not needed.
(242 torr)(27.0 L)=P2(80.0 L)
P2=[(242)(27)]/80 = 81.675 torr
Hence The new pressure is 81.675 torr

The ring shape of the Cartwheel Galaxy is due to collisions with another galaxy.
<h3>What causes the ring shape of the Cartwheel Galaxy?</h3>
The unusual shape of the Cartwheel Galaxy is due to a collision with a smaller galaxy. The recent star burst has lighted up the Cartwheel rim which has a diameter larger than that of the Milky Way galaxy in which our planet exists. The Cartwheel Galaxy is a lenticular ring galaxy which is about 500 million light-years away. This galaxy was discovered by Fritz Zwicky in the year 1941.
So we can conclude that the ring shape of the Cartwheel Galaxy is due to collisions with another galaxy.

Answer:
I dont know if this is correct.. but maybe in the tool row, put graduated cylinder because you use graduated cylinders to measure water and for units put milliliters or liters?? Sorry if this isnt correct i wouldnt know what else to put !
