Two students test the temperature of hot water placed in a glass container and a metal container. After five minutes, they take the temperature of the water in each container. They find the temperature of the water in the glass cup has changed more than the water in the metal cup. They conclude that metal is a better insulator, retaining more heat than glass. The teacher returns their paper and tells them their data is not considered to be valid and reliable. What is most likely the error made in this experiment?

• Thermometer in metal cup was broken
