Question 1372 Deck General

The correct answer is A) dew point. The dew point is the temperature at which a vapor mixture, at a given pressure, begins to condense. When the temperature of a vapor mixture drops to the dew point, the vapor starts to condense into a liquid. This is an important concept in marine engineering, as it helps determine the conditions at which condensation can occur on surfaces, which is relevant for equipment and system design. The other options are incorrect because: B) critical point refers to the combination of temperature and pressure at which a substance changes from a liquid to a gas, or vice versa. C) boiling point is the temperature at which a liquid transitions to a gas at a given pressure. D) bubble point is the pressure at which the first bubble of vapor forms in a liquid at a given temperature.
