Question

Boyle's Law Name Directions: Use Boyle's Law to answer the following questions: Assume constant temp, number of moles and containers can withstand all changes in pressure. 5.50 L of Ne is under 1.05 atm. If the container volume is increased to 8.50 L calculate the new pressure. A 20.0 L tank has a pressure of 3.55 atm. If the pressure is lowered to 15 atm, what would be the resulting volume? A gas has a volume is 2.35 L with pressure of 950 atm. If the original pressure was 2.80 atm, what was the original volume? A gas has volume of 12.5 L and a pressure of 755 mmHg. If the volume was originally 18.5 L, what was the original pressure? A gas in a 15.0 L tank has a pressure of 3.50 atm. For the pressure to be reduced to 850 atm, what would the volume have to be increased to? A gas in a 750 L tank has pressure of 250 kPa, If the original tank had a volume of 2.00 L what was the original pressure? A 45.0 L sample of N, exerts a pressure of 1.25 atm. If the original sample was at 3.5 atm, what was the original volume? An ammonia sample at 1000 mmHg had its pressure dropped from 4.5 atm producing a new volume of 350 mL. Calculate the original volume. Explain using Boyle's Law how drinking through a straw works? Explain how you breathe (what happens to your lungs to "breathe in", and "breathe out" in terms of Boyle's Law. Why is it so difficult to breathe at high altitudes (Give 2 reasons.) 101

if someone could show me how to do 5 of these questions, that would be great. thanks
