When ice is added to lemonade, the lemonade becomes colder due to the heat moving from the lemonade to the ice. This process is based on the principle of heat transfer known as thermal equilibrium.
Here's how it works:
1. Heat naturally moves from a warmer object to a colder object until both reach the same temperature.
2. In this case, the lemonade is at a higher temperature than the ice.
3. When the ice is added to the lemonade, the heat from the lemonade transfers to the ice in an attempt to equalize temperatures.
4. As the heat moves from the lemonade to the ice, it causes the lemonade to lose heat energy, thereby making it colder.
5. The ice absorbs this heat energy and begins to melt, further illustrating the transfer of heat.
Therefore, the correct answer to the question is:
C. Heat moves from the lemonade to the ice.
