Question 651 Deck Safety

The correct answer is A) The vapor pressure of a substance increases with the temperature. This is because the vapor pressure of a substance is directly related to the kinetic energy of the molecules at the surface of the liquid or solid. As the temperature increases, the kinetic energy of the molecules increases, leading to more molecules escaping the surface and entering the vapor phase, which results in a higher vapor pressure. The other options are incorrect because B) vapor pressure decreases as temperature increases, which is the opposite of the correct answer, C) vapor pressure is not affected by temperature, which is not accurate, and D) vapor pressure may increase or decrease as the temperature rises, which is too vague and does not specifically state the correct relationship between vapor pressure and temperature.
