gont get it.. To what temp must a sample of nitrogen at 27 degrees C and 0.625 atm be taken so that its pressure becomes 1.125 atm at constant volume

Question

i used the formula and it still gave me a weird answer

Answer 1

P1/T1 = P2/T2
T must be in Kelvin.

Answer 2

i still don't get it tho. is it 0.625*27/1.125?

Answer 3

Did you see my note about using Kelvin? The 27 is degrees C. It must be changed to KELVIN? Do you know how to do that? ALSO, you didn't multiply right (or you set up the equation wrong).
Make a table
Pressure Temperature
1.125........??
0.625........27 (change to Kelvin).
To solve you cross multiply the ratios.

Answer 4

oooh so 1.125 * 27/0.625

Answer 5

You have the multiplication down BUT you didn't change T of 27 C to KELVIN!

Answer 6

i don't know how to do that

Answer 7

Kelvin = 273.15 + C.

Answer 8

for this one i did
0.625....27+273= 300
1.125... T2
0.625=1.125
300= T2
1.125*300/0.625=540?

Answer 9

That looks ok to me.
