Nick's class did an experiment. They put the same amount of water into four paper cups. To start, the temperature was the same in each cup. They put the cups in four different places. They left them for thirty minutes. Next, they used a thermometer to find the temperature of each cup of water. Predict which location should have the highest temperature.
