Question

Elle wanted to test how temperature affects the rate of evaporation. She had three setups:

Setup 1: Elle placed a container with 1 cup of water at room temperature (25°C).
Setup 2: Elle placed a container with 1 cup of water in a warm room (45°C).
Setup 3: Elle placed a container with 1 cup of water in a cold room (0°C).


What factor did Elle control?

Answer 1

Set up one Ellie PlayStation Center with one cup of water at room temperature 25°C so set up one and three is the correct answer

Step-by-step explanation:

The answer was the temperature at its Actually longer than that so you have to put in the whole set up one so people know it’s the right answer

Answer 2

Temperature

Step-by-step explanation:

Here the factor that Elle is controlling is the temperature. So temperature here is the independent variable and the dependent variable is the rate of evaporation of water. Independent variable is controlled during the experiment setup and the outcome of the dependent variable depends on the independent variable.
