Brittany is very interested in
cryogenics (the science of very low temperatures). With the help of her science teacher
she is doing an experiment on the affect of low temperatures on bacteria. She cools one sample of bacteria to a
temperature of
-
54°C and another to
-
88°C. What was the
temperature difference in the two experiments?
