What is the approximate pressure of a storage cylinder of recovered r404a that does not contain any non-condensable impurities and is stored in a room where the temperature is 80 degrees fahrenheit

Which word expression describes how much to calculate pressure

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
