Lucy is making a cup of hot chocolate. She puts the chocolate and hot water into a cup, and stirs the mixture.
A few minutes later, she notices the cup and the spoon have gotten hot. What made Lucy’s cup and spoon get hot?

Heat was transferred through conduction to the cup and spoon when the hot water molecules collided frequently with the cooler molecules in the cup and spoon and transferred heat.
Heat was transferred through conduction to the cup and spoon when the hot water molecules collided frequently with the cooler molecules in the cup and spoon and transferred heat.
Heat was transferred through conduction to the cup and spoon when the hot water molecules flowed in currents through the cooler molecules of the hot chocolate mix and transferred heat.

The correct answer is:
Heat was transferred through conduction to the cup and spoon when the hot water molecules collided frequently with the cooler molecules in the cup and spoon and transferred heat.
Heat was transferred through conduction to the cup and spoon when the hot water molecules collided frequently with the cooler molecules in the cup and spoon and transferred heat.
The correct response is:
Heat was transferred through conduction to the cup and spoon when the hot water molecules collided frequently with the cooler molecules in the cup and spoon and transferred heat.
Explanation:
In this scenario, heat transfer occurs through conduction. Conduction is the process by which heat energy is transferred between objects or substances in direct contact with each other. When the hot water molecules come into contact with the cooler molecules of the cup and spoon, they collide and transfer heat energy to them. This causes the cup and spoon to become hot.
