The dry adiabatic lapse rate (La)* on Venus is about 10.47K/km, and is similar to that of Earth. This is because the La is governed specific heat (Cp) of the atmospheric gasses and the planet's gravity (g). Specific heat (Cp) is the amount of heat energy in Joules required to raise the temperature of 1 kg of substance by 1 Kelvin. The equation is quite simple. La = g/Cp For Earth: Cp = 1.004 J/kg/K, g = 9.8 m/s2 Earth La = 9.76 K/km For Venus: Cp = 0.85 J/kg/K, g = 8.9 m/s2 Venus La = 10.47 K/km For Mars: Cp = 0.83 J/kg/K, g = 3.7 m/s2 Mars La = 4.50 K/km http://pds-atmospheres.nmsu.edu/education_and_outreach/encyclopedia/adiabatic_lapse_rate.htm The symbol for lapse rate is actually an upside-down L, but I don't know how to do scientific symbols on this browser.
What else can I help you with?
Why is saturated adiabatic lapse rate a lesser than dry adiabatic lapse rate?
The saturated adiabatic lapse rate is lower than the dry adiabatic lapse rate because during the process of condensation, heat is released into the atmosphere, which partially offsets the cooling effect of rising air. This release of heat makes the cooling rate of saturated air less than that of dry air as it ascends through the atmosphere.
Is the adiabatic lapse rate higher when its cloudy or not?
There are two types of adiabatic lapse rates...wet and dry. (wet is also referred to as saturated or moist) To the extent that the cloudiness your question refers to represents saturated air, then no, the wet adiabatic lapse rate would be lower (approximately 1.5C/1000') than the dry adiabatic lapse rate (approximately 3C/1000').
What is an adiabatic lapse rate?
The adiabatic lapse rate refers to the rate at which temperature changes with altitude in a parcel of dry or moist air when there is no exchange of heat with the surroundings. The dry adiabatic lapse rate is approximately 10°C per 1000 meters for dry air, while the moist adiabatic lapse rate varies with humidity but is generally lower due to the release of latent heat during condensation.
Why is the saturated adiabatic lapse rate lower than the unsaturated adiabatic lapse rate?
The saturated adiabatic lapse rate is lower than the unsaturated adiabatic lapse rate because when air is saturated with moisture, the release of latent heat from condensation offsets some of the cooling that would normally occur as the air rises. This results in a slower rate of temperature decrease with height compared to unsaturated air.
When the environmental lapse rate is less than the dry adiabatic rate a parcel of air will be?
Then the air is called "stable" because a parcel of air from the surface lifted upward will drop in temperature at the dry adiabatic lapse rate. If the environmental lapse rate is less, then the lifted air will be cooler and more dense than the surrounding air, and thus stop moving upward through the atmosphere.

Stability prevails when the environmental lapse rate is?
Stability prevails when the environmental lapse rate is less than the adiabatic lapse rate. This means that the temperature of the surrounding air decreases at a slower rate with altitude compared to the dry or moist adiabatic lapse rates, resulting in a more stable atmosphere.
What is an adiabatic lapse rate?
The adiabatic lapse rate refers to the rate at which temperature changes with altitude in a parcel of dry or moist air when there is no exchange of heat with the surroundings. The dry adiabatic lapse rate is approximately 10°C per 1000 meters for dry air, while the moist adiabatic lapse rate varies with humidity but is generally lower due to the release of latent heat during condensation.
How does the moist adiabatic lapse rate compare with the dry-adiabatic lapse rate?
environmental lapse rate involves the actual temperature of the atmosphere at various heights. adiabatic cooling is the cooling of air caused when air is not allowed to expand or compress.
What is the rate of adiabatic temperature change in saturated air?
The rate of adiabatic temperature change in saturated air is approximately 0.55°C per 100 meters of elevation gain, known as the dry adiabatic lapse rate. If the air is saturated and undergoing adiabatic cooling, the rate is around 0.5°C per 100 meters, referred to as the saturated adiabatic lapse rate.
What is the rate of cooling as you increase in elevation?
The rate at which adiabatic cooling occurs with increasing altitude for wet air (air containing clouds or other visible forms of moisture) is called the wet adiabatic lapse rate, the moist adiabatic lapse rate, or the saturated adiabatic lapse rate.
When the environmental lapse rate is between the dry and moist adiabatic lapse rates conditions are described as what?
When the environmental lapse rate is between the dry and moist adiabatic lapse rates, conditions are described as conditionally unstable. This means that the atmosphere is stable when unsaturated and unstable when saturated, indicating the potential for convective storms to develop under the right conditions.
Why is the saturated adiabatic lapse rate lower than the unsaturated adiabatic lapse rate?
The saturated adiabatic lapse rate is lower than the unsaturated adiabatic lapse rate because when air is saturated with moisture, the release of latent heat from condensation offsets some of the cooling that would normally occur as the air rises. This results in a slower rate of temperature decrease with height compared to unsaturated air.
When the environmental lapse rate is less than the dry adiabatic rate a parcel of air will be?
Then the air is called "stable" because a parcel of air from the surface lifted upward will drop in temperature at the dry adiabatic lapse rate. If the environmental lapse rate is less, then the lifted air will be cooler and more dense than the surrounding air, and thus stop moving upward through the atmosphere.
Why is there a difference between the dry and moist adiabatic lapse rates?
Air that is rising at the dry adiabatic rate can simply cool at the rate at which the decreasing pressure forces it to. Once it cools to its dew point at the lifting condensation level, it must condense some of its moisture in order to cool anymore (it is already saturated at this point). Condensation is a process that releases latent heat into the atmosphere, warming the air. Therefore, this heat released counteracts some of the adiabatic cooling that continues to take place as the air rises, and the net effect is a rate of cooling that is reduced. This is the saturated (or moist) adiabatic lapse rate.
The rate of temperature change 0.6 degrees C for every 100 m of saturated air as it rises or falls is the moist adiabatic?
That statement describes the environmental lapse rate of saturated air, also known as the moist adiabatic lapse rate. This rate signifies how quickly the temperature of saturated air changes as it ascends or descends through the atmosphere under adiabatic conditions. The specific value of 0.6 degrees Celsius per 100 meters is a typical approximation for the moist adiabatic lapse rate.
