Astudent notices that the saucer below a coffee cup becomes warmer after coffee is poured into the cup. energy was transferred from –

the cup to the saucer by conduction.

the saucer to the cup by conduction.

the cup to the saucer by convection.

the saucer to the cup by convection.

The correct option is A) the cup to the saucer by conduction

Explanation:

Conduction can be described as a process in which heat from an object that is warmer is transferred to an object which is cooler until both the objects have an equal amount of heat. When coffee is poured in a cup, the cup gets heat and its heat is greater than the saucer which is cooler. As a result of conduction, heat passed to the saucer from the cup until both have equal amounts of heat. Hence, the correct option is A.
