The correct statement regarding various types of molecular speeds area...
Increasing temperature increases Umpsc
- As the temperature of a gas increases, the average kinetic energy of the gas molecules also increases.
- This increase in kinetic energy leads to an increase in the speed of the molecules.
- Consequently, a greater fraction of molecules will have speeds greater than the most probable speed (Umps).

In a sample of gas at a given temperature, molecules with extremely low and high speeds are less
- In a sample of gas at a given temperature, the distribution of molecular speeds follows a Maxwell-Boltzmann distribution.
- This distribution shows that the majority of molecules have speeds clustered around the most probable speed, with fewer molecules having extremely low or high speeds.
- Therefore, molecules with extremely low and high speeds are less common in a sample of gas at a given temperature.
In conclusion, increasing the temperature of a gas increases the average molecular speed (Umps), and molecules with extremely low and high speeds are less common in a sample of gas at a given temperature.
