Why do you need to specify the temperature when reporting a density?

Density changes with temperature because volume changes with temperature. Density is mass divided by volume. As you heat something up, the volume usually increases because the faster moving molecules are further apart. Since volume is in the denominator, increasing the volume decreases the density.

What is effect of temperature on density?

Density of a substance decreases with increase in temperature because increases the volume.

What is the importance of measuring temperature?

The measurement of body temperature can help detect illness. It can also monitor whether or not treatment is working. A high temperature is a fever.

Why do you need to measure and record the temperature of the water after making measurements?

In many of the experiments we do in Chemistry it is required that we measure the actual temperature of a liquid. When temperature changes are being measured, one can reduce the error by taking both temperatures with the same thermometer.

How does temperature affect density of gas?

Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density.

Does density increase with temperature?

Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.

What is the effect of temperature on density Brainly?

Answer: Density decreases with increase in temperature and increases with decrease in temperature..

What is temperature and importance of temperature?

Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).

Why is temperature important in water quality testing?

Temperature is a critical water quality and environmental parameter because it governs the kinds and types of aquatic life, regulates the maximum dissolved oxygen concentration of the water, and influences the rate of chemical and biological reactions.

What is the importance of recording water temperature in the laboratory for this experiment?

It is important to measure water temperature. By doing so, we can see the characteristics of the water such as the chemical, biological, and physical properties of the water, as well as the possible health effects.

Why is the temperature and pressure important when giving the density of oxygen and nitrogen?

Density of gases changes with pressure and temperature because gases are compressible fluid and because they are compressible, when pressure increases molecules come closer to each other which means increase in density and when pressure drops molecules of gases become free to expand and get away from each other which …
