Question

The largest bubble chamber in the world is 15 ft. in diameter and contains 7259 gal of liquid hydrogen at a temperature of -247 degrees Celsius. If the temperature is dropped by 11 degree Celsius per hour for 2 consecutive hours, what is the new temperature?

Answer 1

well, clearly the temperature is now

-247 - 2*11 = -269

The only problem is that hydrogen freezes at -259

Answer 2

What does that mean for this problem then?

Answer 3

it means it is ill posed. The math is correct, but the problem doesn't take into account real-world conditions.

Just ignore it, as this is an algebra class, not a physics class. Still, you might point it out to the teacher, not that it will do any good.
