Question

Imagine that you have an ideal gas in a 6.70 L container, and that 1450 molecules of this gas collide with a square-inch area of the container at any given instant. If the volume is increased to 40.2 L at constant temperature, how many collisions will occur per square inch of this larger container? Enter the number of collisions per square inch

Answer 1

they could collide 241.66 molec / in² by increasing the volume to 40.2L

Step-by-step explanation:

ideal gas:

Boyle Law: at constant temperature the pressure of a gas varies inversely with the volume

• V1 * P1 = V2 * P2
• P = F / A

∴ V1 = 6.70 L;

∴ P1 = 1450 molec / in²

∴ V2 = 40.2 L

⇒ P2 = (( 6.70 L ) * ( 1450 molec/in²)) / 40.2 L

⇒ P2 = 241.66 molec/in²
