(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 21 °C After Shaking Unknown What best predicts the unknown temperature? Group of answer choices Less than 21 °C because heat energy is formed from the energy used in shaking Greater than 21 °C because heat energy is formed from the energy used in shaking Less than 21 °C, because the total energy of the system after shaking is higher than before shaking Greater than 21 °C, because the total energy of the system after shaking is higher than before shaking
