The rms speed of the molecules of a gas at 137°C is 183 m/s. Calculate the mass of a single molecule in the gas.
Answer in kg.
If He gas has an average kinetic energy of 7690 J/mol under certain conditions, what is the root mean square speed of Cl2 gas molecules under the same conditions? Answer in m/s -What would the pressure, P, of a gas be if the mean free path was 133 cm? Assume the gas is at room temperature, T = 22.6°C, and the diameter of the molecule is d = 1.50 × 10-10 m.
Answer in Pa
In the Olympiad of 700 BCE, athletes competing in the standing long jump used handheld weights called halters to lengthen their jumps. The weights were swung up in front just before liftoff and then thrown backward during the flight.
