a sample of gas occupies 3.75 liters ar 16.91 lb/sq in and 25 degrees Celsius. at what temperature in fahrenheit will it occupy 4 liters at 1 atm?

my problem is finding one of the variables to solve the equation

i defined my variables here:
volume 1= 3.75 liters
volume 2= 4 liters
Temp1=25 degrees celsius+273= 298 kelvin
Temp2= (this is what we are finding)
pressure1= 1 atm
pressure2= ????? i dont understand how to find the second pressure

if someone can please show me how to find that second pressure variable that would be so helpful

also do i have to convert the 16.91 lb/sq in for the volume?

It isn't cold. Not for the 30-second transit from a car to a building, anyway.

A 85.5 kg astronaut is working on the engines of a spaceship that is drifting though space with a constant velocity. The astronaut turns away to look at Earth and several seconds later is 39.1 m behind the ship, at rest relative to the spaceship. The only way to return to the ship is to tho a wrench directly away from the ship. The wrench has a mass of 0.577 kg, and the astronaut throws the wrench at a speed of 24.0 m/s. How long does it take the austronaut to reach the ship?

If it asks you to find critical numbers is it [a,b] or (a,b)

Is only (a,b) used for rolle's theorem and mean value theorem?

So if it gives you a function 4/x +x [1,2] find the critical numbers you count 2 as a critical number? If the same equation is used for rolle' theorem you dont count 2?
