2. Two students are setting up a demonstration to show different ways that heat can be transferred from a hot plate to a thermometer. They are provided with the following materials: Beakers, Thermometers, Water, Sand, and Hot Plates. The procedure is as follows. 1. Fill beaker #1 with water, and beaker #2 with sand. 2. Put a thermometer in the beaker with water and a thermometer in the beaker with sand. 3. Record the temperature of the sand and the water. What are the next steps and which description accurately represents the transfer of heat? A. Step 4: Place each beaker on a separate hot plate and tums on the hot plate. Step 5: Record the temperature every minute. Explanation: Beaker #1 demonstrates heat transfer by convection and beaker #2 demonstrates heat transfer by conduction B. Step 4: Place each beaker on the lab bench. Step 5: Record the temperature every hour. Explanation: Both beakers demonstrate heat transfer by convection. C. Step 4: Place each beaker in the window. Step 5: Record the temperature every 5 minutes. Explanation: Beaker #1 demonstrates heat transfer by radiation and beaker #2 demonstrates heat transfer by conduction. D. Step 4: Place each beaker on a separate hot plate and turns on the hot plate. Step 5: Record the temperature every minute. Explanation: Beaker #1 demonstrates heat transfer by both conduction and convection and beaker #2 demonstrates heat transfer by conduction
