50 POINTS! I really need help with these pressure and volume questions from Boyle's Law. PLEASE HELP 1.If a sample of gas has a volume of 100.0ml when the pressure is 50.0kPa, what is the volume when the pressure is increased to 400.0kPa, assuming temperature and number of moles is held constant?

2. What pressure would be required to take 100.0ml of a gas at 103.0kPa and squish it down to 2.00ml, assuming temperature and number of moles is held constant?

4. If the temperature and number of moles are held constant, what would be the new volume if 2.00cm3 of a gas at 3.00atm is changed to 0.0200atm?

7. What pressure must be applied to a sample of Freon gas having a volume of 325L at 20.0°C and 723Torr to permit the expansion of the gas to a volume of 975L at 20.0°C?

1) = 100ml = 0.1 L

2) = 50kPa

So,

Same, formula as above,

By the formula,

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
