Why potential temperature constant during dry adiabatic?
Potential temperature remains constant during a dry adiabatic process because no heat is exchanged with the environment; the system is insulated. As an air parcel rises or descends, it expands or compresses adiabatically, causing changes in temperature while maintaining the same potential temperature. This is due to the conservation of energy in the absence of heat transfer, allowing the potential temperature to remain unchanged.
Why the temperature in a flask tha contains dry peas doesn't change at the room temperature?
The temperature in the flask remains constant because the peas act as insulation, limiting heat transfer between the inside and outside of the flask. This insulation effect prevents the temperature from changing easily.
When a sling psychrometer is slung around why does the wet bulb become colder than the dry bulb?
The wet bulb cools down because as it is swung in the air, the water on the wick evaporates, which requires energy and heat, leading to a drop in temperature. The dry bulb temperature remains constant as it is not affected by the evaporation process.
What is the heat capacity of dry air and how does it affect the temperature changes in the atmosphere?
The heat capacity of dry air is the amount of heat needed to raise the temperature of a given amount of air by 1 degree Celsius. Dry air has a lower heat capacity compared to water vapor, meaning it heats up and cools down more quickly. This affects temperature changes in the atmosphere by causing rapid temperature fluctuations, especially in dry regions where there is less water vapor to moderate temperature changes.
What is the specific heat of dry air and how does it affect the temperature changes in a system?
The specific heat of dry air is approximately 1.005 kJ/kgC. This means that it takes 1.005 kilojoules of energy to raise the temperature of 1 kilogram of dry air by 1 degree Celsius. The specific heat of dry air affects temperature changes in a system by determining how much energy is needed to raise or lower the temperature of the air. Higher specific heat means it takes more energy to change the temperature, while lower specific heat means it takes less energy.
What characteristics greatly added to vertebrate success in relatively dry environments?
A constant body temperature.
What is difference between dry heat and moist heat?
Dry heat is the absolute substance temperature without accounting for the modulating effects of water vapor in the substance. Moist heat is the relative substance temperature when accounting for the modulating effects of water vapor.
Why did the wet-bulb temperature record a lower temperature then a dry-bulb temperature?
the evaporation off the moisture on the wet bulb absorbs the heat.
Why does when you first step out of the shower you feel cold but as you are dry you feel warmer even though the room temperature does not change?
When you step out of the shower, your wet skin evaporates water, which absorbs heat from your body, making you feel cold. As you dry off, less water evaporates, so less heat is lost, causing you to feel warmer. Even though the room temperature remains the same, your body's heat loss changes due to the wetness of your skin.
When heat drying fruit what temperature will heat affect vitamins?
Two minutes after you dry it, it will burn. But it will taste better than properly drying it.
Why is temperature lower on a wet bulb the a dry bulb?
Because the process of evaporation absorbs heat from the bulb.
What is cT cP mT mT?
cT= continental Tropical cP=continental Polar mT=maritime Tropical there is also : mP=maritime Polar cA=continental Arctic c(continental)=dry/not very humid m(maritime)=wet/humid T(Tropical=warm P(Polar)=cold A(Arctic)=very cold these are all terms used during a weather topic
