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 convection to the cup and spoon when the hot water molecules moved through the cooler molecules in the surrounding air and transferred heat.
Heat was transferred through convection to the cup and spoon when the hot water molecules moved through the cooler molecules in the surrounding air 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 collided frequently with the cooler molecules in the cup and spoon and transferred heat.
Heat was transferred through convection to the cup and spoon when the hot water molecules radiated into 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.
The correct answer is:

When Lucy added hot water to the cup, the hot water molecules had a higher temperature compared to the cup and spoon. Through the process of conduction, heat energy transferred from the hot water molecules to the cooler molecules in the cup and spoon. This transfer of heat occurred as the hot water molecules collided frequently with the cup and spoon molecules, causing them to vibrate and increase in temperature. Consequently, the cup and spoon became hot as a result of the conduction of heat from the hot water to the cooler materials.
