Gas Laws Asynchronous

Which is the correct form of the combined gas law?

• PV/T = PV/T
• PT/V = PT/V
• TV/P = TV/P
• P/T = V/n

What does the combined gas law become when temperature is held constant? 

• P/T = P/T
• PV = PV
• P/V = P/V
• V/T = V/T

Pressure is

• defined as the mass that an object exerts when at rest

• measured in Newtons

• defined as the number of moles of substance divided by the mass of the substance

• defined as the force per unit area

• measured in grams
