Answer:
This question is incomplete
Explanation:
The question is incomplete without the options. However, when a metal (in this case what the pennies are made of) is left in direct contact with the heat from the sun, it conducts this heat and becomes hot. This process is called thermal conduction. The thermal energy is readily accepted by the material in which the pennies are made of thereby increasing the thermal energy of the penny coin which then makes the pennies hot after being left under the sun.
Answer:
C. Heat flowed from the surrounding hot air to the cooler jar and transferred heat to the pennies by conduction.
