What is the average speed actually the root mean square speed of a argon atom at 27 C?
Hence, the rms speed is 432.2 m/s.
Which of the following gases has the lowest average speed at 25 C?
The gas with the highest molar mass is H2Se, which means it will have the lowest average speed. The answer is a. H2Se.
Which gas has the lowest speed?
Argon
Which of the following sample of gas has the highest root mean square speed?
Velocity will be highest for lowest molecular mass. Hence, CH4 will have maximum rms velocity.
Which of the following gases has the lowest average speed?
The Questions and Answers of At 298 K, which of the following gases has the lowest average molecular speed? a)CO2 at 0.20 atmb)He at 0.40 atmc)CH4 at 0.80 atmd)NO at 1.00 atmCorrect answer is option ‘A’.
Which molecules of the following gases will have the smallest root mean square speed?
FREE Expert Solution The only difference the gases have is their molar masses (M). The molar mass (M) is in the denominator so the larger the molar mass (M) of the gas, the smaller the μrms would be. (E) Ar will have the smallest room mean square speed (μrms).
Which gas has the highest root mean square speed at 25 C?
Which of the following gases will have the highest RMS velocity at 25∘C? CO has the lowest molecular mass, hence, it has the highest RMS velocity.
What are the five assumptions or ideas of the kinetic molecular theory?
The kinetic-molecular theory of gases assumes that ideal gas molecules (1) are constantly moving; (2) have negligible volume; (3) have negligible intermolecular forces; (4) undergo perfectly elastic collisions; and (5) have an average kinetic energy proportional to the ideal gas’s absolute temperature.
What are three ideas in the kinetic molecular theory?
The simplest kinetic model is based on the assumptions that: (1) the gas is composed of a large number of identical molecules moving in random directions, separated by distances that are large compared with their size; (2) the molecules undergo perfectly elastic collisions (no energy loss) with each other and with the …
Which particle has the most energy?
steam, being in gas form, has the highest energy as particles have more kinetic energy and they move more vigorously than in ice or water that are in solid and liquid form respectively.
