According to Boyle's Law, what happens to the volume of a gas if the pressure increases while temperature remains constant?

• Volume increases

• Volume decreases

• Volume stays the same

• Volume doubles

Answer explanation

According to Boyle's Law, if the pressure of a gas increases while the temperature remains constant, the volume of the gas decreases. This inverse relationship means that higher pressure results in a smaller volume.

Which variable must remain constant for Charles's Law to apply?

• Pressure

• Volume

• Temperature

• Amount of gas

Answer explanation

For Charles's Law to apply, the pressure must remain constant. This law states that the volume of a gas is directly proportional to its temperature when pressure is held steady.

What is the formula for Boyle's Law? You can use your notes. Teacher copy is posted in Google Classroom under 11.2 Notes now.

• Pressure x Temp

  =

  Pressure Final X Temp Final

• P₁V₁/P₂V₂

• P₁V₂=P₂V₁

• P₁/V₁=P₂/V₂

Answer explanation

Boyle's Law states that the pressure of a gas is inversely proportional to its volume at constant temperature. The correct formula is P1V2 = P2V1, which shows this relationship.

Volume / Temp = Volume Final / Temp Final is the equation for which Law

• Charles Law

• Boyle's Law

• Newton's Law

• Pick Charles Law

Answer explanation

The equation Volume / Temp = Volume Final / Temp Final represents Charles Law, which states that the volume of a gas is directly proportional to its temperature when pressure is constant. Thus, the correct choice is Charles Law.

Answer explanation

Using Charles's Law, V1/T1 = V2/T2. Plugging in the values: 2.0 L / 300 K = V2 / 600 K. Solving for V2 gives V2 = (2.0 L * 600 K) / 300 K = 4.0 L. Thus, the new volume is 4.0 L.

Answer explanation

Using Boyle's Law (P1V1 = P2V2), we have (1.0 atm)(5.0 L) = (2.0 atm)(V2). Solving for V2 gives V2 = (1.0 atm)(5.0 L) / (2.0 atm) = 2.5 L. Thus, the new volume is 2.5 L.

Answer explanation

Using Charles's Law, V1/T1 = V2/T2. Here, V1 = 3.0 L, T1 = 273 K, T2 = 546 K. Solving for V2 gives V2 = (3.0 L * 546 K) / 273 K = 6.0 L. Thus, the volume at 546 K is 6.0 L.

Answer explanation

Using Boyle's Law (P1V1 = P2V2), where P1 = 1.0 atm and V1 = 8.0 L, we find P2. Rearranging gives P2 = P1V1/V2 = (1.0 atm)(8.0 L)/(4.0 L) = 2.0 atm. Thus, the final pressure is 2.0 atm.
