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?

Responses
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.
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.
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.
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.
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.
You sure
Yes, I am sure. Conduction is the transfer of heat between objects that are in direct contact with each other, and in this case, the hot water molecules are in direct contact with the cup and spoon. When the hot water molecules collide with the cooler molecules in the cup and spoon, they transfer heat to them. Therefore, heat is transferred through conduction.
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.
The correct response would be:
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:
Conduction is the transfer of heat energy between objects in direct contact. In this case, when Lucy poured the hot water into the cup, the hot water molecules started colliding with the cooler molecules in the cup and spoon. These frequent collisions resulted in the transfer of heat from the hot water to the cup and spoon, causing them to get hot.
