The cylinder in the figure has a moveable piston attached to a spring. The cylinder's cross-section area is 10 cm2, it contains 0.0055 mol of gas, and the spring constant is 1500 N/m. At 15oC the spring is neither compressed nor stretched.
a) How far is the spring compressed if the gas temperature is raised to 170oC? Express your answer to two significant figures and include the appropriate units.

Suppose you form a dipole from two point charges (with a magnitude of charge, q). the postive charge is located at the point x=y=0, z=d/2. and the negative charge is located at x=y=0, z=-d/2.
three point charges are placed on the y-axis a charge q at ya a charge -2q at the origin and a charge q at y-1 . such
Two kilomoles of a monatomic ideal gas are at a temp of 300K. The gas expands reversibly and isothermally twice its original volume. Calculate the work done by the gas. (Note that for an ideal gas U is proportional to T, so the change of U = 0 in ..
