A sample of neon gas has an initial volume of 2.5L at 300 K. What is the new temperature of the gas(both in K and Celsius degrees) if the pressure remains constant, when the volume is changed to each of the following values: a. 5.00L b. 7.50L c. 1.50L d. 500mL e. 50.0mL f. 750mL

Assuming ideal gas, we can use Charles Law:
V1 / T1 = V2 / T2
where
V = volume
T = absolute temperature (K)
It's just direct substitution. I'll do (a):
V1 / T1 = V2 / T2
2.5 / 300 = 5 / T2
Solve for the new temperature (T2):
2.5(T2) = 300(5)
T2 = 1500 / 2.5
T2 = 600 K
Now try doing the others. Hope this helps~ `u`
