Assertion (A): Absolute humidity is defined as the total weight of water vapor present in the air per unit volume.
Reason (R): The relative humidity indicates the percentage of moisture in the air compared to its total capacity at a specific temperature.
Name the process by which liquid vapour changes into solid form
Which of the statements given above is/are correct?
i. Fog is a cloud that forms with its base at or very near to the ground, leading to poor visibility.
ii. Mist contains less moisture than fog and is primarily formed over mountains when warm air rises and meets cold surfaces.
iii. Nimbus clouds are thin, detached clouds that are always white in color.
iv. Cumulus clouds resemble cotton wool and are typically formed at altitudes between 4,000 - 7,000 meters.
Assertion (A): Dew forms when moisture is deposited on cooler surfaces under conditions of high relative humidity and clear skies.
Reason (R): Dew can only form when the temperature is at or below the freezing point.
Which of the statements given above is/are correct?
i. Water exists in the atmosphere in three forms: gaseous, liquid, and solid.
ii. Absolute humidity refers to the percentage of moisture in the atmosphere compared to its full capacity.
iii. The dew point is defined as the temperature at which air is saturated with moisture.
iv. Relative humidity is the weight of water vapor per unit volume of air.
Which of the statements given above is/are correct?
i. Evaporation is primarily caused by the loss of heat from water.
ii. Condensation occurs when the air temperature is lowered to the dew point.
iii. Sublimation refers to the direct transition of water vapor into liquid form.
iv. Hygroscopic condensation nuclei assist in the condensation process by absorbing water.
Assertion (A): The classification of clouds is primarily based on their altitude and appearance.
Reason (R): Different cloud types, such as cirrus and nimbus, indicate specific weather conditions and precipitation levels.
Which type of clouds are formed at a height of (4000-7000 m)?
Assertion (A): Evaporation of water increases when the temperature of the surrounding air rises.
Reason (R): Higher temperatures enhance the capacity of air to hold moisture, leading to increased evaporation.
Which of the given statement(s) is/are true?
Statement I: Condensation occurs when air is heated and expands.
Statement II: Condensation can lead to the formation of clouds, dew, frost, or fog.
The %age of moisture present in the atmosphere as compared to its full capacity is known as
