What is molecular speed of molecules?
For example, many molecules have speeds around 500 m/sec, whereas few molecules have speeds around 1000 m/sec. The speed that corresponds to the peak of the curve is called the most probable speed. More molecules travel at (or close to) this speed than any other.22 fév. 2021Does amount of molecules affect speed?
The speed of the molecules in a gas is proportional to the temperature and is inversely proportional to molar mass of the gas. In other words, as the temperature of a sample of gas is increased, the molecules speed up and the root mean square molecular speed increases as a result.What is the Maxwell distribution law of molecular speed?
