Ice Cubes Melting in Lemonade On a sweltering hot summer day, two friends set up a lemonade stand in front of their house. They made the lemonade in the kitchen and take it outdoors to the stand. Their neighbor stops by, so one friend pours a cup of lemonade for them. The neighbor enjoys the refreshment, but says the lemonade would be even better if it was colder. The two friends have an idea that ice cubes could reduce the temperature of the lemonade. So, they dash into the house and bring a bowl of ice cubes out to the lemonade stand. They add the ice cubes to the pitcher of lemonade. 

When do the water molecules in the ice cubes have their lowest particle motion? 

A. After the ice cubes fully melted into the lemonade

B. Before Kim put the ice cubes into the pitcher of lemonade 

C. After William drank the lemonade 

D. While the ice cubes were melting in the lemonade

B. Before Kim put the ice cubes into the pitcher of lemonade
