Solution
Immersion heater: The purpose of the immersion heater in this experiment is to increase the temperature of the liquid. It does this by transferring energy to the liquid.
Polystyrene cup: The purpose of the polystyrene cup is to reduce thermal energy loss from the liquid to the container. Polystyrene is a good insulator, so it helps to keep the heat within the liquid and prevent it from escaping to the surroundings.
Joulemeter: The purpose of the joulemeter is to measure the energy being provided to the immersion heater. This allows you to keep track of how much energy is being used to heat the liquid.
Lid for the polystyrene cup: The purpose of the lid for the polystyrene cup is to reduce thermal energy loss to the surroundings. By placing a lid on the cup, it helps to prevent heat from escaping from the top of the cup.

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

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?
Which device is used to measure the heat energy transferred in a physical or chemical process?Options:A) ThermometerB) CalorimeterC) HygrometerD) Barometer
