Question 1 pts
1.(2 points) In the Boyle’s law experiment, what pressure unit was used to
gauge the pressure?
2.(2 points) According to Boyle’s law, as the volume of a gas increases, the pressure .
3.(6 points) A sample of gas occupies a volume of 10.5 L when the pressure is
14.3 psi. Use Boyle’s Law to calculate the volume (L) when the pressure is
increased to 19.6psi. Show the calculation.
Your Answer:
Millimeters of mercury (mmHg)
According to Boyle's law, if the volume increases, the pressure decreases, they have an inversely proportional relationship.
V2 = P1 * V1 / P2 = 14.3 psi * 10.5 L / 19.6 psi = 7.66 L.
1.Pounds per square inch or psi. 2.decreases
3.Pressure = 7.66 L.
Question 2 pts
1.(4 points) In the Charles’s law experiment, what happened to the syringe as the temperature increased?
2.(6 points) A sample of gas occupies a volume of 57.9 L at 300K. Use Charles’s Law to calculate the volume (L) when the temperature is 264K. Show the calculation.
Your Answer:
As the temperature increased, the pluger on the syringe will rises V1/T1= V2/T2
V1=57.
