Before heating 4 qt. saucepan 8 qt. stockpot 24.5 °C Temp. 24.5 °C Temp. After heating for 5 minutes at a rate of 30 Joules per minute 4 qt. saucepan 8 qt. stockpot Temp. Temp. 1) In which container - the 4 qt. saucepan or the 8qt. stockpot – did the water gain more energy or did both gain the same amount? Explain your reasoning? 2) Is the temperature expected to increase, decrease or remain the same after heating? Explain your reasoning?

Please help me complete question 1 and 2

## Model 1 – A Pot of Water ### Before Heating - **4 qt. Saucepan** - Initial Temperature: 24.5°C - **8 qt. Stockpot** - Initial Temperature: 24.5°C ### After Heating for 5 Minutes at a Rate of 30 Joules per Minute - **4 qt. Saucepan** - Temperature: Not specified - **8 qt. Stockpot** - Temperature: Not specified ### Discussion Questions 1. **Energy Gain in Containers:** - In which container - the 4 qt. saucepan or the 8 qt. stockpot - did the water gain more energy, or did both gain the same amount? - **Explanation:** Since both containers were heated at the same rate (30 Joules per minute) for the same time period (5 minutes), both gained the same amount of energy, totaling 150 Joules. 2. **Temperature Change:** - Is the temperature expected to increase, decrease, or remain the same after heating? - **Explanation:** The temperature is expected to increase for both containers after heating since energy is added in the form of heat. The actual temperature change depends on the water volume and the capacity of each pot, but given the same energy input, the smaller volume in the saucepan may show a larger temperature increase than the stockpot.
