A tank having a volume of 0.10m' is filled with oxygen at a pressure of 4.0 x 10'Pa and temperature of 47C. Later it is found that, because of a leak, the pressure has dropped to 3.0 x 10'Pa and the temperature has decreased to 27C. Find. (a) the initial mass of oxygen and (b) the mass that has leaked out.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
