Question

Robert places six eggs in a pot of boiling water (100°C) and six eggs in a pot with water at 80°C. He keeps the eggs in the water for ten minutes. Then he removes the eggs, cracks them, and counts the number of eggs that are fully cooked from each pot. Which variables are the independent and dependent variables? Check all that apply.

[] the number of eggs


[] the water temperature


[] the number of fully-cooked eggs


[] the time in the water

Answer 1

The water temperature is the independent variable, and the number of fully cooked eggs is the dependent variable. The number of fully cooked eggs relies on the temperature therefore making it dependent.
