Question

everybody who lives in arizona knows that if you park your car outside during the day in the summer the interior becomes very hot. the air conditioning can cool the air inside the car fairly quickly, but it still feels uncomfortable inside because the metal and glass of the car is still hot. the air conditioning cant cool these parts very well, even though the air, glass and metal all start at the same temperature when you turn the air conditioning on. why is this?

Explanation:

Heat capacity is the amount of heat energy required to change the temperature of a substance. Substances with smaller heat capacities heat up and cool down more quickly. Since the car still feels uncomfortable inside, it implies that the air (with a larger heat capacity) cools down faster than the glass and metal (with smaller heat capacities). So the heat capacity of the air is larger than that of the glass and the metal.

Answer:

The heat capacity of the air is larger than that of the glass and the metal.
