A quantity of a gas has an absolute pressure of 400 kPa and an absolute temperature of 110 degrees kelvin. When the temperature of the gas is raised to 235 degrees kelvin, what's the new pressure of the gas? (Assume that there's no change in volume.)
A. 854.46 kPa
B. 1.702 kPa
C. 510 kPa
D. 3.636 kPa

Its A

110   400
235     x

Then cross multiply.... 110 times x = 110x
400 x 235 = 94000
then all that's left is to divide.

94000/110  :) = 854.46

Answer;

= 854.46 kPa

Explanation;

Use the equation from Charle's Law:  

P1/T1 = P2/T2  

P1 = 400 kPa

T1 = 110 K

P2 =?

V2 = 235 K

400kpa / 110k = 3.6  x 235k

 = 854.46 kPa
