The answer is C, because the moon does rotate it just rotates at the perfect time for us to never side the other side of it.
Whewww!! What class is this for
BE CAREFUL! If it is a controlled lab wear saftey equiptment. But it can blow up. So careful...
You can say that if the volume of the gas is halved, the pressure is doubled.
The expression shows that pressure and volume are inversely proportional if temperature and amount of gas is held constant. This means that if volume goes down the pressure needs to go up. That also means that in order to maintain the K value, if pressure is doubled the volume needs to be halved and if the pressure is halved the volume needs to be doubled.
This relationship only works if we assume everything else (Temperature and moles of gas) to be constant.
