2 students are experimenting to see if the amount of water affects who quickly it heats to 100*C. They decided to heat one beaker of 500 mL of water to 100*. They heat the second beaker of 250 mL of water to 100*C. They time how long it takes each to reach the desired temperature. They record their results. What is a piece of qualitative data from the experiment?

A. 500 mL of water

B. time if takes the water to heat up

C. temperature of the water
