Look at the image below. Molly boils some water and pours it into a beaker. She records its temperature, covers it for 5 minutes, and then records its temperature again. She repeats this experiment with two different types of insulating material: newspaper and bubble wrap. Her results are below. If she repeated this investigation with no lids on the beakers, would the beakers transfer more or less energy to the surroundings?
Question
Look at the image below. Molly boils some water and pours it into a beaker. She records its temperature, covers it for 5 minutes, and then records its temperature again. She repeats this experiment with two different types of insulating material: newspaper and bubble wrap. Her results are below. If she repeated this investigation with no lids on the beakers, would the beakers transfer more or less energy to the surroundings?
Solution
Without the lids on the beakers, the beakers would transfer more energy to the surroundings. This is because the lids act as insulators, reducing the amount of heat energy that can escape from the beaker to the surroundings. Without the lids, there would be more heat energy lost to the surroundings, thus increasing the energy transfer.

Cathy hypothesizes that plastic foam insulates cold drinks better than metal or ceramic materials do. To testthe hypothesis, she fills cups made from these materials with equal amounts of cold water. She records thetemperature of the water in each cup, using scientific thermometers, every 10 minutes until the waterreaches room temperature. Which of these conditions must be the same for this experiment to be valid?Group of answer choicesThe thermometer that is in each cupThe material of each cupThe ending temperature of the water in each cupThe starting temperature of the water in each cup PreviousNext
