1. What is the equation for Boyle's Law?.
2. What does the letter P stand for?
3. What are the units for P?
4. What does the letter V stand for?
5. What are the units for V?

1. P1V1 = P2V2

2. P stands for pressure

3. Units for Pressure are atm and Pa

4. V stands for volume

5. Units for volume is in mL

Explanation: Boyle's Law is a gas law that states the relationship between pressure and volume of a gas.

P•V = c or P =1/k

P in Atmospheres V in Liters

P1V1 = P2V2

Initial pressure P1 = 20 atm

Initial volume V1 = 1 L

final volume V2 = 1 L + 12 L = 13 L

final pressure P2 = variable to find

P1V1 = P2V2

Dividing both sides of the equation by V2 gives you:

P1V1 / V2 = P2

Explanation: A gas law; one of the very first with 2 variable; circa 1662 A.D.
