A truck carrying oxygen cylinders is filled with oxygen at `-23^(@)C` and at a pressure of 3 atmosphere in Srinagar , Kashmir.Determine the internal pressure when the truck drives through Madras. Tamilnadu. Where the temperature is `30^(@)C`.

Options

A. 2.64 atm.
B. 1.64 atm.
C. 1 atm.
D. 3.64 atm.

Answer

d

Explanation

`P_(1) = 3 atm, P_(2) = ?`
`T_(1) =- 23 + 273 =250 K`
`T_(2) =273 + 30 = 303 K `
`( P_(1))/( T_(1)) = ( P_(2))/( T_(2)) , ( 3)/( 250 ) = ( P_(2))/( 303) `
`P_(2) = ( 3 xx 303)/( 250) =3.64 atm.`
