Gas Laws - Boyle's and Charles'

the relationship of the different properties of gas

STANDARD TEMPERATURE & PRESSURE

• 273 K

• 1 atm

Boyle's Law

• The relationship between the volume and pressure of a gas.

• States, "For a fixed amount of gas at a constant temperature, the volume of a gas increases as the gas's pressure decreases. Likewise, the volume of a gas decreases as the gas's pressure increases.

Multiple Choice

What type of relationship to pressure and volume have?

• direct
• inverse
• no relationship
• I don't know

Multiple Choice

What is the formula for Boyle's Law?

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

Multiple Choice

A gas occupies 4.98 L at 2.6 atm of pressure. What volume does it occupy at 1.8 atm pressure?

• 12.9 L
• 0.72 L
• 7.2 L
• 3.44 L

Charles's Law cont.

The straight line for the gas indicates that volume and temperature are in direct proportion.

Charles's Law cont.

When temperature increases, volume increases, and when temperature decreases, volume decreases.
