no
temp and pressure
It has no effect. Only mass and volume have an effect on density.
from the equation of state pressure = density * gas constant * temperature
Temparature effect on density
yes
With increase in temperature , the density of fluids decreases and their vapour pressure increases. There's no direct relationship for temp-density of HYdrocarbons. But temperature and density are inversely proportional and the constant of proportionality varies from fluid to fluid. For hydrocarbons that constant can be calculated keeping in mind its VP, boiling point at ambient conditions and its constituents.
Temperature, pressure, and common ion effect
By heating the density is lowered.
it does becuz temp it the speed particles are moving so it eects by how spread out the atoms are for the density
The effect of decreasing incubation time on optical density is that optical density decreases. Incubation time and optical density have a proportional relationship.
it has no effect. density of a substance is the same no matter the size or shape of the sample.
