Question

A volume of gas with an initial volume of 4.0 liters at 3.7C had the temperature changed to 3C. What is the new volume if pressure remains constant?

Answer 1

in this type of question

just equate the initial moles and final moles

n= pv/rt

n =moles

v= volume

r= gas constant

t= temperature

now equating initial and final moles we get

4/276.3 = v ( final)/276

v(final) = 3.99 approx = 4
