Question 8 Multiple Choice Worth 3 points)
(01.04 HC)
A group of students performed an experiment to prove the law of conservation of energy in the experiment, a flask containing water at room temperature was shaken vigorously for a few minutes
The table shows a partial record of the temperature of the water before and after shaking
Experimental Record
Temperature
Before Shaking 19 °C
After Shaking
Unknown
What best predicts the unknown temperature?
Less than 19 °C, because the total energy of the system after shaking will be lower
• Greater than 19 °C, because the total energy of the system after shaking will be higher
Less than 19 C, because the energy used for shaking raises the kinetic energy of the water molecules
Greater than 19 °C, because the energy used for shaking raises the kinetic energy of the water molecules
