Question 124251This question is from textbook Precalculus
: I really need help solving this word problem?
If the pressure of a gas is constant, then the volume of an enclosed gas varies directly as the absolute temperature. Given that a 3.46 liter sample of neon gas has a pressure of 0.926 atmoshperes at temperature 301 degrees K, use a power formula to calculate the volume of this sample at 338 degrees K assuming the pressure does not change. You do not need to use the pressure as part of your formula.
My answer options are:
A.3.46 liters
B.3.87 liters
c.4.21 liters
D.4.85 liters
Please help me, I'm real stumped. I don't understand this problem. Thanks This question is from textbook Precalculus

"the volume of an enclosed gas varies directly as the absolute temperature"
__ direct variation means they both change value the same way (by multiplying or dividing)

not sure what the "power formula" is...

the absolute temperature changes a little more than 10% (from 301 to 338)

a similar change in the volume would be 3.46 plus around .35

the only answer anywhere close is B
