AND
b.Assume the temperature changed at a stedy rate for 25 minutes. Using your answer for part A for how much the temp. must change to freeze the helium, write and solve an inequality to dtermine HOW MUCH THE TEMPERATURE MUST CHANGE EACH MINUTE.

A) 272 +3
b) im not sure about it but i think you should use 3/25!
