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 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.

r u sure
I apologize for the confusion. 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.
are you sure this time
Yes, I am sure this time. Heat transfer through conduction occurs when there is direct contact between two objects or substances, resulting in the transfer of heat energy from one to the other. In this case, the hot water molecules coming into contact with the cup and spoon would transfer heat to them through conduction.
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 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, transferring heat.
Explanation:
When Lucy poured hot water into the cup of hot chocolate, the hot water molecules had higher kinetic energy than the cooler molecules in the cup and spoon. As a result, the hot water molecules collided with the cooler molecules in the cup and spoon, transferring some of their kinetic energy to them. This transfer of thermal energy from the hot water to the cup and spoon is known as conduction. As a result, the cup and spoon became hot as the heat from the hot water spread to them through these collisions.
