A container with a volume of 3 liters contains a gas at 27oC and 2 atmospheric pressures. This Find the work that gas does during the following operations. a) Its temperature is increased 5 times in constant volume b) From its initial state, its volume is increased to 4 times at constant pressure. c) Its volume is doubled from the beginning.

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
