A gas is held at a constant pressure while its volume decreases from 450 mL to 200 mL. What will the final temperature be if the initial temperature is 25.0 degrees celsius? (Express temperature in K)

Answer:

V- Volume T- Temperature
V1= 450mL V2=200mL
T1= 298°k T2= ?

450mL 200mL
------ = ------- (cross multiply)
298°k T2

450(T2) 59,600
-------- = --------
450. 450

T2 = 132.44444445°k
