Question

A volume of 450 cubic centimeter is measured at a pressure of 740 mm Hg and a temperature of 25.4 oC.

What is the volume in liter? Pressure in pound per square inch and temperature in degree Kelvin?

Answer 1

Given Volume = 450 cc

Pressure = 740 mm Hg

Temperature = 25 . 4$\degree$ C

Volume in liters = $\dfrac{volume \ in \ cubic \ centimetres}{1000}$ = $\dfrac{450}{1000}$

Volume in liters = 0. 45 ltr

Pressure in pound per square inch = $\dfrac{Pressure \ in \ mm \ Hg}{0.019}$ = $\dfrac{740}{0.019}$

Pressure in pound per square inch = 38947.36 psi

Temperature in kelvin = Temperature in $\degree$C + 273 = 25.4 + 273

Temperature in kelvin = 298.4 kelvin
