C) the coldness and heat moved back and forth until the lemonade cold off
Explain your thinking Describe the "rule" or reasoning you used for your answer.
The answer is B) the heat from the lemonade moved into the ice
Explanation: Heat is the energy transferred as a result of temperature difference between two system. It always flow from the higher temperature to the lower temperature. It never flows the other way. In this case the lemonade has the higher temperature than the ice, so heat flowed from the lemonade to the ice. As a result the lemonade is said to lose heat while the ice gained heat.
When heat is applied to a solid substance, for example ice, the bonds which holds it breaks and it undergoes a change in phase to become a liquid. This change in phase from solid to liquid is called melting.
The ice melted into water in the question given.
