Homework Help: Physics repost please check

Posted by Mary on Friday, April 20, 2007 at 2:48am.

Good morning. This is a repost. The system is telling me my calculations is incorrect. I thought a fresh pair of eyes would help. Please tell me what I am doing wrong.

Suppose a monatomic ideal gas is contained within a vertical cylinder that is fitted with a movable piston. The piston is frictionless and has a negligible mass. The area of the piston is 3.06 10-2 m2, and the pressure outside the cylinder is 1.02 105 Pa. Heat (2109 J) is removed from the gas. Through what distance does the piston drop?

V= area *distance

You know P, area, and work. Solve for distance.

According to the formula provided
P(area x distance)= work

solve for distance

distance = work - P/ area

this is where it get confusing for me

P= 1.02 x 10^5 Pa
A= 3.06 x 10^-2 m^2
W= ? I am unsure how to get he value of work

Work is heat, and heat is work. It was given.

Please check my working out. The system is saying it is wrong.

PV = W

PV = 2109J

V = 2109J/ 1.02 X 10^5Pa

V = 0.020676471m^3

Area x distance = 0.020676471m^3

distance = 0.020676471/ 3.06 x 10^-2m^2

distance = 0.6757 m
