Step-by-step explanation:
Remember, a hypothesis is an assumption that may only be accepted after been tested.
a. A formal question using chemistry language for this experiment could be;
Among plastic, foam, and paper, which has a better thermal insulating capacity?
b. Hypothesis: Plastic has a better thermal insulating capacity.
c. The Experimental variable is all the different kinds of materials used in cup production.
d. Three important control variables include;
- amount of cocoa in the cup,
- size of the cup,
- cup's texture
e. Note in other to test your hypothesis, we need to measure the initial and final temperatures in all three kinds of cups.
