Gasoline use contributes to air pollution
Gasoline is a toxic and highly flammable liquid. The vapors given off when gasoline evaporates and the substances produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.
Answer: Option (B) is the correct answer.
Explanation:
Thermal energy is defined as the energy present within the molecules of a substance.
Also, when two objects that have different temperature and they are in contact with each other then heat will always flow from hot object to cold object.
For example, if a metal spoon is placed in a hot cup of coffee then heat will flow from hot coffee to the metal spoon.
Therefore, we can conclude that during heat transfer, thermal energy always moves in the same direction: HOT COLD.
