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?
Group of answer choices
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
