The question is:

The freezing point of helium is -272 degrees celsius. The original temperature of a sample of helium is 3 degrees celsius.

a.How much must the temperature change to ensure that helium freezes?


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.
