Question

A 175 mL sample of neon had its pressure changed from 75 KPa to 150 KPa. What is its new volume?

Answer 1

The new volume of the neon is: `V_2=87.5mL`

Explanation:

Boyle's law states that pressure is inversely proportional to volume for a fixed quantity of an ideal gas at a constant temperature.

The mathematical formula is : `V_2=(P_1V_1)/(P2)`

Here we have: `P_1=75KPa; P_2=150KPa; V_1=175mL`

Then: `V_2= (75KPa*175mL)/(150KPa)`

`V_2= (cancel(75KPa)1*175mL)/(cancel(150KPa)2)`

`V_2=87.5mL`
