Turtles are cold blooded, meaning they use the Sun to keep warm. A student hypothesizes that his pet turtle will prefer swimming in warm water. He places his turtle on a rock in the middle of the bathtub, and measures how much time the turtle spends off of the rock during a five minute period. He conducts the experiment under four conditions in the bathtub: no water, warm water, cool water , and room temperature water. In this experiment, which is the control group ?

Room temperature water

Explanation:

Neither the amount of water nor the temperature of the water has been changed.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
