14.0 moles of an ideal gas are compressed slowly and isothermally from STP (273 K/100) until it occupies one quarter of its initial volume. the gas is then allowed to expand quickly and adiabatically back to it's initial volume. find the highest and lowest temperatures and pressures obtained by the gas and indicate them on a PV diagram. (please explain the process/show work)

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.

An electron is traveling with initial kinetic energy k in a uniform electric field. the electron comes to rest momentarily after traveling a distance d. (a) what is the magnitude of the electric field
