What is low air density?
= What is low air density? = well, high or low are relative concepts. Normally the standard air density of the air is defined as the density of the air at 15ºC and at sea level pressure (standard conditions), what give a value of 1,225kg/m3. This way, we can talk about high or low air density related to the standard value. Air density depends on temperature and pressure. The colder the temperature the higher the density is, and the higher the height in the atmosphere the lower the density becomes. In the Everest peak, e.g., air density can be lower than 0,5. Meanwhile in the Antarctica (at sea level) the density could reach values higher than 1,5.
What is the definition of low density in chemistry?
A definition doesn't exist for low density. The values depends on the application or material.
What is the density of a solid object that has a mass of 15.0 g and displaces 11.6mL of water when placed into a graduated cylinder initially containing 20.0 mL of water?
density of object = 15.7g/15.9 ml = 0.987 g/ml. At 4ºC the density of water is 1.0 g/ml so this object will FLOAT in water at that temperature. Even at room temperature, the density of water is slightly greater than 0.987, so this item will still "probably" float.
What is laititude?
Latitude is measured from the equator, with positive values going north and negative values going south.
Which stellar properties has the greatest range in values?
The property that has the greatest variation is a star's density.
What are four types of measurement are?
According to Stanley Smith Stevens, the four levels of measurement are:nominal - for example counting balls of different colorsordinal - where the measured values have an order - for example small, medium, largeinterval - where a distance is defined between the measured values - for example, Celsius temperatureratio - where we can divide values and get a meaningful answer - for example length and weightthe 4 types of measurements are mass,volume,distance,and temperature-ZOEY
When Measured properties that have different values at different times are?

What is the rackett equation?
The Rackett equation is used to predict the density of a pure liquid vs temperature based on its critical properties. One density value is required to calculate the Rackett constant in the equation, then the critical properties Tc, Vc, and Pc are used to estimate new density values as the temperature changes.

What is the temperature of distilled at room temperature?
This depends greatly upon the temperature the water. At 4oC the density is approximately 1000 kg/m3 (or 1 g/cm3) - more acurately though the density would be 999.97 kg/m3 (or 0.9997 g/cm3). Values for the density of pure water (H2O) have been calculated over a wide range of temperatures. At room temperature (22oC) The density of water is 997.77 kg/m3 (or 0.99777 g/cm3)
What is the difference if any of volume to mass ratio of warm and cold water?
The volume to mass ratio you speak of is usually called density, "density = mass / volume"The density of water does change a little bit depending on the temperature. According to Wikipedia, the density decreases as temperature increases, meaning that the same mass of water takes up less space at a higher temperature. Check out the details and values on Wikipedia for more information.
What do density values mean?
density is the mass of unit volume of the substance.
What are values that have been measured or counted?
They are data.
