One mole of oxygen gas is at a pressure of 5.30 at m and a temperature of 31.0°C.
a) If the gas is heated at constant volume until the pressure triples, what is the final temperature?
b) If the gas is heated so that both the volume and pressure are doubled, what is the final temperature?
Two identical pellet guns are fired simultaneously from the edge of a cliff. These guns impart an initial speed of 32.0 m/s to each pellet. Gun A is fired straight upward, with the pellet going up and then falling back down, eventually hitting the gr..
