Which one of the following is NOT produced by condensation?
Dew, smog, fog, clouds
.
Which process would result in the release of 600 calories of latent heat per gram of water?
Condensation
. In the process of condensation, water vapor is converted to liquid water. This process, which releases 600 calories of heat (the latent heat of condensation), is an important source of energy for our storms.
Which of the following will not cause air to become unstable?
Question Answer | Which of the following will NOT cause air to become more unstable? subsidence of an air column | Which of the following would NOT be associated with stable atmospheric conditions? afternoon thunder showers |

Which of the following is not a physical mechanism that causes air to rise?
Which of the following is NOT a physical mechanism that causes air to rise?
Adiabatic cooling
. The opposite of sublimation is deposition.
Which one of the following refers to the energy that is stored or released during a change of state of water?
latent heat
, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.
Which of the following is an example of condensation?
Clouds
are a large-scale example of condensation, and generally form when water vapor in warm air rises to meet cold air higher in the atmosphere. As the warm air cools and the molecules coalesce and stick together, drops of water or ice crystals form and surround dust particles in the air.
Which event is an example of condensation?
Condensation is the process of water vapor turning back into liquid water, with the best example being those
big, fluffy clouds floating over your head
. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
Does condensation need heat?
Latent heat is the heat energy required to change a substance from one state to another. … Energy is required to change from solid to liquid, liquid to gas (evaporation), or solid to gas (sublimation). Energy will be released to change from liquid to solid (fusion), gas to liquid (condensation), or gas to solid.
Is heat released during evaporation?
In the case of evaporation,
the energy is absorbed by the substance
, whereas in condensation heat is released by the substance. For example, as moist air is lifted and cooled, water vapor eventually condenses, which then allows for huge amounts of latent heat energy to be released, feeding the storm.
Is energy released or absorbed during melting?
Note that melting and vaporization are
endothermic processes
in that they absorb or require energy, while freezing and condensation are exothermic process as they release energy.
What are 4 ways that air can be forced upward?
– There are four lifting mechanisms that form clouds:
Orographic Lifting, Convection, Convergence, and Updraft
. – Orographic lifting is when air cannot go through a mountain, and so it flows over it. – Frontal Lifting is when less dense warm air is forced to rise over cooler, denser air as a weather fronts move.
What weather does each front bring?
When a front passes over an area, it means a change in the weather. Many fronts cause weather events such as
rain, thunderstorms, gusty winds, and tornadoes
. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds.
What two factors affect relative humidity?
Humidity depends on
the temperature and pressure of the system of interest
. The same amount of water vapor results in higher humidity in cool air than warm air. A related parameter is the dew point.
Which gas is most important for understanding the processes that take place in the atmosphere?
Oxygen
is the most active and is continually changing, but may be considered to impact terrestrial processes more than atmospheric ones.
What is latent heat of vaporisation Class 9?
The term latent heat of vaporisation can be defined as
the amount of heat needed for the conversion of 1kg of liquid at its boiling point to gas at same temperature
. It differs among different liquids.
What is the reverse process of condensation?
Condensation
is the
process
where water vapor becomes liquid. It is the
reverse
of evaporation, where liquid water becomes a vapor.
