a) Given volume "=450\\ cubic \\ centimeter"

Pressure of "=" 740 mm Hg

Temperature"\\ =" "25.4^{o}C"




Volume in litre =


We know that ,


"1\\ cubic\\ centimeter=0.001\\ liter"


"=\\dfrac{450}{1000}=0.45\\ liter"



Pressure in pound per square inch "="


"1mm\\ of\\ mercury=0.0019\\ pounds\\ per\\ square\\ inch\\"



"\\dfrac{740}{14.3092}=51.715" "pounds \\ per\\ square\\ inch"



Temperature in degree kelvin =


"25.4^{o}C=273+25.4=289.4^{o}K"



b) The formula to convert into Fahrenheit will be=


"(20^{o}\\times\\dfrac{9}{5})+32=68^{o}F"
