Question

Pedro is planning to model how changes in weather affect evaporation from

lakes. For his first experiment, he wants to test how humidity affects the
evaporation rate. He places one beaker with 300 mL of water in a dry area,
and he places another beaker with 300 mL of water near a humidifier.
What is the dependent variable in Pedro's experiment?
A. Evaporation rate
B. Temperature
c. Humidity
D. Volume of water

Answer 1

Evaporation rate is the dependent variable in Pedro's experiment

Step-by-step explanation:

it is the variable that is being measured and is expected to change in response to changes in humidity. The independent variable is humidity, which is being manipulated by placing one beaker near a humidifier and the other in a dry area. Temperature and volume of water are not being directly manipulated in this experiment and are therefore not the dependent variable.
