As discussed earlier the change in temperature has different effects on a substance when applied in different phases viz. solid, liquid or gas. Therefore, there are specific formulas for expressing the relation between the temperature and density of the substance in different phases. For ideal gas: P = ρRT Where, P = … See more Density is the measure of the number of molecules of a substance present in a specific volume. It is the characteristic property of a … See more The temperature of a substance is the measure of its heat i.e. it is the property used to explain how hot or cold a substance is using a number of scales viz. Fahrenheit, Kelvin, Celsius, etc. It is an illustration of the … See more The density of a substance decreases as the temperature increases and vice versa. This indicates that these two physical properties of a substance are inversely related to each other. When a density vs. temperature graph is … See more Relative density is also known as specific gravity. It is actually the density of a substance relative to another substance that is being used as reference material. It is used to check … See more WebApr 8, 2024 · The density of air depends on many factors and can vary in different places. It mainly changes with temperature, relative humidity, pressure and hence with altitude (take a look on the air density table …
