Responses
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 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.
