Why does air pressure decrease as altitude increases? Why is evaporation a cooling process? Why is evaporation called a surface phenomenon? How does the movement of air masses affect weather? What does the rate of evaporation depend on?
On a warm or hot summer day, the ground, sidewalks and streets become very warm and if it begins to rain on this warm or hot surface, the water will evaporate which becomes vapor and rises. This evaporation fog, or steam fog, is named because it resembles steam rising from the surface....
If water evaporates, that means it's become vapor, and vapor should be at 100C or more at normal pressure, right? Individual particles do not have a temperature, they have a kinetic energy. To have a temperature, you need a very large number of particles acting as a single system. ...
When liquid water evaporates, it becomes water vapor and enters the atmosphere. This process is essential to kickstart the water cycle, a continuous movement of water on, above and below the surface of the Earth. Evaporation occurs when heat from the sun causes water from oceans, rivers, ...
It is possible that extracellular freezing took place on those nights, which then changed the electrolyte balance in the cells. It is known that due to vapor pressure difference, there is drift of symplastic water to apoplastic ice, which then leads to intracellular desiccation (Sakai and Larcher...
(ms−1),esis the saturation vapor pressure (kPa),eais the actual vapor pressure (kPa),es − eais the saturation vapor pressure deficit (kPa), Δ is the slope of the saturated vapor pressure in relation to air temperature (kPa °C −1) and γ is the psychrometric constant (...
What effect will the following change have on the rate of the reaction between these gases? The temperature is decreased at a constant volume. Explain how the vapor pressure of a compound is related to the liquid-vapor equilibrium and its equilibrium constant. How would it vary w...
Water vapor has a high concentration in the atmosphere as well, but its concentration is a bit lower than that of carbon dioxide. The greenhouse gas methane is a very potent greenhouse gas, as it combines with other elements to form thole gases, which trap heat in the atmosphere. ...
Influenza virus survival vs humidity as measured by water vapor pressure. From Shaman & Kohn, PNAS 2009. [3] Scale is loge; 4.5 = 90% survival, 1.5 = 4.5% survival Scientists warn that blasting a hair dryer up your nose should be left to professionals. Their research shows that low abso...
The odours were distributed in air-conditioned rooms by means of vaporizers (Iscent, Zeewolde, The Netherlands). Pilot studies were conducted in order to determine the proper odours to be used and their concentrations. We aimed to achieve a perceived intensity of 35–50 mm on a visual ...
