The average speed at temperature T^(@)C ...

The average speed at temperature `T^(@)C` of `CH_(4)(g)` is `sqrt((28)/(88))xx10^(3)ms^(-1)`. What is the value of T ?

A

`240.55^(@)C`

B

`-32.45^(@)C`

C

`3000^(@)C`

D

`-24.055^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
b

(b) `sqrt((8RT)/(piM))=sqrt((28)/(88))=sqrt((7)/(22))`
`(8xx8.314xxT)/(pixx16xx10^(-3))=(7)/(22)xx10^(6)`
`T=(1000xx2)/(8.314)=240.55K`
`T^(@)C=240.55-273=-32.45^(@)C`
