Question

julie was ironing her clothes for school and noticed when she hung up the ironed clothes they were still hot from being ironed. she decided to investigate the heat - change that occurred when the clothes were being ironed. which of the following best explains how the heat was transferred to increase the temperature of the clothing?

a the temperature of the clothing increased because the thermal energy of the iron was transferred to the clothing by the collision of the atoms in the iron and the clothes.

b the temperature of clothing increased because the thermal energy of the iron was transferred to the clothing by the thermal energy that traveled through space to heat the clothing.

c the temperature of clothing increased because the thermal energy of the iron was transferred to the clothing by the thermal energy rising to the clothing causing the clothes to be heated.

d the temperature of clothing increased because the thermal energy of the iron was transferred to the clothing by electrical energy traveling to the clothes through the iron causing the temperature of the clothes to increase.

Explanation:

Heat transfer from the iron to the clothing occurs by conduction. Conduction is the transfer of heat energy through direct contact and the collision of atoms. When the hot iron touches the clothes, the atoms in the iron collide with the atoms in the clothes, transferring thermal energy. Option A describes this conduction - based heat transfer process. Option B describes radiation (thermal energy traveling through space), Option C describes convection (thermal energy rising), and Option D has an incorrect description as electrical energy is not directly involved in the heat transfer from iron to clothes in this context.

Answer:

A. The temperature of the clothing increased because the thermal energy of the iron was transferred to the clothing by the collision of the atoms in the iron and the clothes.
