If ambient room temperature is a constant 22 degrees celsius how much of a liter of water would evaporate in 12 hours and is the size of the exposed surface area of 1 liter relevant to evaporation?

-- the area of the exposed surface
-- the airflow over the exposed surface
-- the temperature of the liter of water
-- the air pressure at the exposed surface
-- the relative humidity of the air in the room
-- the transparency of the liter container
are all relevant to the rate of evaporation.

What is the volume of a gas is reduced from 4 L to 0.5 L while the temperature is held constant. What does the pressure of the gas do?
The gas pressure increases by a factor of 8. The relevant equation is pV = nRT. Since nothing on the right side of this equation changes, the product on the left side must remain constant. The volume is stated to decrease by a factor of 4/0.5 or 8; therefore the pressure must increase by the same factor.
What are relevant measurable characteristics of water?
Some relevant measurable characteristics of water include pH levels, temperature, turbidity (clarity), dissolved oxygen levels, and levels of contaminants such as heavy metals or pesticides. These characteristics are important for assessing water quality and its suitability for various uses.
Why do tables of densities always include the temperature for which the listed values hold?
Densities of substances can change with temperature due to thermal expansion or contraction. Including the temperature at which the listed density values hold helps provide accurate and relevant information for various applications and calculations.
ASTM for shaw dew point meter?
The ASTM standard relevant to Shaw dew point meters is ASTM D1143, which covers the procedure for estimating the dew point temperature of a constant-volume, open-cup apparatus. This standard provides guidelines for the test method and apparatus used to determine the dew point temperature of a gas. Make sure to check the specific version of the standard for the most accurate and up-to-date information.
Does the shape of container affect the time it takes for water to evaperate?
Yes, the shape of the container can affect the rate of evaporation. A container with a larger surface area will typically allow for faster evaporation compared to a container with a smaller surface area. This is because more water molecules are exposed to the air in a larger container, leading to increased evaporation.

What does k correspond to in a direct variation function?
k is the constant of variation and is the gradient (slope) of the relevant graph.
Why is melting of butter is reversible whereas curdling of milk is irreversible?
Melting is a phase change, which is entirely controlled by temperature (pressure is also relevant but under normal circumstances, air pressure is approximately constant). Curdling is a chemical change. The process that leads to a particular chemical is much more complicated than a change in temperature.
Why different fractions of crude oil are collected at different temperatures?
Because crude oil is a mixture of different chemicals - mainly hydrocarbons - that have different evaporation temperatures. Roughly speaking, when the crude is heated, its temperature rises until it reaches the lowest vaporisation temperature. The temperature then remains more or less steady as the heat input is used as the latent heat of vaporisation for the relevant compound. When [almost] all of that compound has evaporated, the temperature starts rising again until it reaches the next varorisation temperature, and so on.
What does water have to do with measuring temperature?
The fixed points on the Celsius scale, for measuring temperature are based on the freezing and boiling points of water and, to that extent water is relevant to the measurement of temperature.
What is the point at in which a graph intersects the y-axis.?
It is called the y-intercept and is the constant term in the relevant equation.
Define relevant range in accounting?
an increase or decrease on a company's fixed costs is however not only dependent on the relevant period but also on the relevant production range. The total fixed costs will remain constant if the relevant production range can be handled by the same number of production units, producing fewer steps. If a certain step ( certain cost level) encompasses the entire relevant range of activity, the costs are entirely fixed.
Variable cost fluctuates in total as activity changes but remains constant on a per unit basis over the relevant range true or false?
true
Is the ambient temperature in a 1300 petrol engine high or low?
The ambient temperature in this case refers to the temperature outside the engine. This is relevant for calculations related to heat engine. The ambient temperature will of course vary, but it is usually somewhere around 300 K.
What is a relevant constant?
A relevant constant is a fixed value in a mathematical or scientific equation that does not change. It is typically represented by a symbol and serves as a factor or parameter in the equation. Constants help define relationships between variables and provide consistency in calculations.
What services does Constant Contact provide?
Constant Contact is an email service that allows a person or business/group to email multitudes of patrons/customers with information that they deem relevant. It can be used for work such as event announcements, newsletters, or even simple reminders.
