decrease
remain the same
increase

anonymous · Answer

Holding temperature constant but decreasing the volume will increase the pressure, which is caused by having more collisions per unit time per unit area.

okay thank you

If 1.60 mol of O2 is substituted for the 1.60 mol of He, holding the volume and temperature constant, the average molecular speed will

remain the same
decrease
increase

anonymous · Answer

If temperature is constant, average kinetic energy is constant.

Heavier molecules at the same temperature have lower speeds than lighter ones. KE = 0.5 m v^2 and is proportional to T.

anonymous · Answer

thr second one would be decrease?

anonymous · Answer

??

aravindg · Answer

Yes O2 being more heavier the speed decreases.
