Why is it necessary to state the temperature with a density value?

It is necessary to indicate the temperature when giving the density of liquids because temperature effects the density of many liquids. For example, water increases in density as it becomes colder.

The volume of an object changes in different temperature, so therefor it's density changes with it's volume. Volume is size, and size is dependant on temperature.

∙ 13y agoDensity and volume are temperature dependent variables. For example, under normal conditions in which the external pressure of a body is held constant and the body's volume is not constricted, as its temperature increases, so will its volume, while its density will decrease. this is due, generally speaking, to the added kinetic energy gained by the atoms, ions, and/ or molecules that make up the body in question.

∙ 12y agothat is because density varies with temperature. Most objects expand as temperature increases, thereby increasing in volume. Because density is mass divided by volume, density usually decreases with increasing temperature

What is the value for water density?
1 gram per cubic centimeter
How hot is tepid in Fahrenheit?
Tepid is just a description of temperature not an actual temperature so there is no actual value for it.
What does density of water mean?
The density of anything is the ratio of the weight (really the mass) to the volume that the material occupies. Water was involved in the original definition of units of mass and volume, so it has a rather special value of density. To a good approximation, the density of water is 1 gram per milliliter.
Temperature related to saponification value?
Heat the flask on a steam bath.
What is the best definition of temperature?
Temperature is a measure of the motion of particles in a substance.
What condition is pressure altitude and density altitude the same value?
At standard temperature.
What is the density of h20?
The density of H2O is 0.9982g/mL at 20°C. Usually a value of 1 is used at room temperature.
Under what condition is pressure altitude and density altitude the same value?
at standard temperature
What is the density of petrol?
737.22 kg/m^3 The density depends on a whole range of factors including purity and Temperature. Use the above as a guide though but in situations where the value of density is critical, take a sample to the lab for them to determine the correct value.
Is density a solid or gas?
Density isn't a state, it's a value.
1 liter of hydrogen is equal to how many kg?
It depends on the temperature and pressure of hydrogen or to have the hydrogen density value.
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 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.
Why is mercury used in calibration of blaine permeability apparatus?
i think mercury has high value density and its density depend on temperature for small size volumes, it is suitable (little change of mercury volume result significant mass value & easy Measurable) saeedhoseini
Why is it necessary to specify the temperature when giving a value for k?
The rate constant, k, varies with temperature, so the temperature at which it has been determined must be given. In general a 10 oC temperature increase will double the rate of a chemical reaction.
What value is needed to convert mass to volume in stoichiometry problem?
Density (at a given temperature) is the parameter that relates the mass to the volume of any substance.
What is temperature and density?
Temperature is a physical property that gives a quantitative value for how cold or hot something is. Density is a bit easier, just look at its formula D=M/V, it's essentially the amount of stuff taking up a certain area. (the mass per unit of volume.)
