1.	By what factor does the average velocity of a gaseous molecule increase when the absolute temperature is doubled ?
Answer» 1.4 `2.0` `2.8` `4.0` Solution :Average velocity `(vecc)=sqrt((8RT)/(PIM))` If ABSOLUTE TEMPERATURE is doubled, new average velocity `=sqrt((8R.2T)/(piM))=sqrt(2)BAR(C )=1.4bar(c )`
