Gas Laws Exam

What is the formula for Boyle's Law?

• P₁V₁=P₂V₂
• P₁V₁/P₂V₂
• P₁V₂=P₂V₁
• P₁/V₁=P₂/V₂

A container holds 600 L of air at pressure of 2 atm. If the pressure on the gas is increased to 5 atm, what will its volume become? Use Boyle's Law.

• 240 L

• 235 L

• 230 L

A gas occupies 4.98 L at 2.6 atm of pressure. What volume does it occupy at 1.8 atm pressure? Use Boyle's Law

• 12.9 L

• 0.72 L

• 7.2 L

• 3.44 L

What is the new volume of the gas if the pressure on 350 L of oxygen at 1.5 atm is decreased to 1 atm? Use Boyle's Law.

• 420 L

• 350 L

• 525 L

• 285L

The pressure on a sample of gas is increased from 1.0 atm to 3.0 atm. If the new volume is 0.52 L, find the original volume. Use Boyle's Law.

• 0.52 L

• 1.56 L

• 0.173 L

What is the formula Charles' Law?

• V = T
• VT = VT
• T₁ / V_{1 =} T₂ / V₂
• V₁ / T₁ = V₂ / T₂
