What was the difference in relative humidity between noon and 5 pm how was the relative humidity affected by air temperature?
Relative humidity typically decreases from noon to 5 PM due to rising air temperatures, which increase the air's capacity to hold moisture. As temperatures rise, the relative humidity can drop even if the absolute amount of moisture in the air remains constant. This results in a lower relative humidity reading in the afternoon compared to midday. The specific difference in relative humidity would depend on the actual temperature and moisture content at those times.
A parcel of air is at 20 and has a saturation vapor pressure at 24 mb If the water vapor content actually exerts a vapor pressure of only 12mb in 20 air the relative is What would the ap?
To calculate the relative humidity, you can use the formula: [ \text{Relative Humidity} = \left( \frac{\text{Actual Vapor Pressure}}{\text{Saturation Vapor Pressure}} \right) \times 100 ] In this case, the actual vapor pressure is 12 mb, and the saturation vapor pressure is 24 mb. Thus, the relative humidity is: [ \text{Relative Humidity} = \left( \frac{12 \text{ mb}}{24 \text{ mb}} \right) \times 100 = 50% ] Therefore, the relative humidity of the air parcel is 50%.
What is the relative humidity of 25c air that contains 10gm of water vapor show work?
To find the relative humidity of air at 25°C containing 10 grams of water vapor, we first need to determine the saturation vapor pressure at that temperature. At 25°C, the saturation vapor pressure is approximately 23.8 grams per cubic meter (g/m³). Assuming we have a volume of 1 cubic meter of air, the relative humidity can be calculated using the formula: [ \text{Relative Humidity (%)} = \left( \frac{\text{Actual Vapor Content}}{\text{Saturation Vapor Content}} \right) \times 100 ] Substituting the values: [ \text{Relative Humidity} = \left( \frac{10 , \text{g/m}^3}{23.8 , \text{g/m}^3} \right) \times 100 \approx 42.02% ] Thus, the relative humidity of the air is approximately 42%.
Oxygen has three different isotopes that occur naturally in different amounts if 99 is oxygen- 16 0.04 is oxygen- 17 and 0.20 is oxygen-18 calculate the relative atomic mass of oxygen?
To calculate the relative atomic mass of oxygen, you multiply the mass of each isotope by its natural abundance (in decimal form), and then sum these values. The calculation is as follows: [ \text{Relative atomic mass} = (16 \times 0.990) + (17 \times 0.0004) + (18 \times 0.0020) = 15.84 + 0.0068 + 0.036 = 15.8868 ] Thus, the relative atomic mass of oxygen is approximately 15.88 amu.
Why relative retention time used for related substances?
Relative retention time is used for related substances in chromatography because it allows for easy comparison of retention times between different compounds on the same chromatographic system. By expressing retention times relative to a reference compound, such as the main peak of interest, it helps in identifying and quantifying related substances accurately and efficiently.
How a device to measure relative humidity was made in BC times?
A device to measure relative humidity in BC times was done with a simple twig placed parallel to the ground and mounted several feet up. When relative humidity increases, the twig points down, and when it decreases, the twig points up.

What humidity is required to paint acrylic latex?
everything you want....acrylic is great...just use your medium knowing there is no right or wrong....not ever...one love...... Actually, in these type of things, there is a right and wrong. Acrylic house paint should not be applied if the humidity is higher than 85%. Drying times are normally calculated at 50% relative humidity.
How do you calculate dry bulb temperature and wet bulb temperature to get relative humidity?
To calculate relative humidity, you first need to determine the dry bulb temperature (DBT) and the wet bulb temperature (WBT) using a psychrometer. Once you have these temperatures, you can use a psychrometric chart or a formula that incorporates both temperatures. Relative humidity (RH) can be calculated using the equation: ( RH = \frac{E}{E_s} \times 100 ), where ( E ) is the actual vapor pressure derived from the WBT and ( E_s ) is the saturation vapor pressure derived from the DBT. Alternatively, many online calculators can compute RH directly when provided with DBT and WBT.
How do you use relative ferquency in a sentence?
You wouldn't. First of all, frequency is spelled wrong precluding its use. Second frequency is not relative; it is a constant in time (events/sec). There are not relatively more waves /sec in blue light than in red, there are more, period. Similarly, there are not relatively more of less of anything since this is an exact constant that is relative only if time changes.
Why are constellations seen at different places and time?
Constellations appear to be in different places at different times due to the Earth's rotation on its axis. As the Earth rotates, the position of the observer relative to the stars changes, causing different constellations to become visible. This is why different constellations can be seen in the night sky at different times and in different locations on Earth.
How do you compare King Lear with The Homecoming?
They are very different plays that were written at very different times by very different playwrights and so are virtually incomparable. I think the thing that does compare is the power struggle. I hope this helps but if you added a little more detail in the question and context then I could help more.
