The volume of a gas is changed along the curved line between a and b in the drawing. do not assume that the curved line is an isotherm or that the gas is ideal. what is the work done for the process?

Asystem containing an ideal gas at a constant pressure of 1.22×10^5 pa gains 2140 j of heat. during the process, the internal energy of the system increases by 2320 j. what is the change in volume of the gas?

Which two particles are found in the center of an atom

What is the speed of an object at a given moment?
