What is the volume percent of Toluene in room temperature?
percent volume of toluene at room temperature is 31.84%.
Which is more effective single extraction with a large volume of solvent or several small volume extraction?
Several small volumes is more effective.
What is controlled and uncontrolled extraction in double extraction steam turbine?
The extraction of steam can either be controlled or uncontrolled. In an uncontrolled extraction the pressure of the extracted steam will decrease with an increase in extraction flow from the turbine. In a controlled extraction the extraction pressure is kept constant as extraction flow is increased or decreased.
What will happen to pressure when gas expands and volume increases?
As the pressure increases, the volume wil decrease.
How does temperature affect the volume of substance?
An increase in temperature will cause an increase in volume, while a decrease in temperature will cause a decrease in volume.
What causes density to decrease?
an increase in volume and/or a decrease in mass
Does a decrease in temperature results in a decrease or in crease in the volume of gas?
Temperature is directly proportional to volume i.e. as temperature increases volume of gas also increases and as it decreases, the volume also decreases
What happens to the volume of the gas if the pressure increased?
Volume decrease.
What is happening to the substances mass and volume to cause this decrease in density?
A decrease in density would indicate a reduction in mass relative to the volume. If the mass decreases but the volume remains the same or increases, then the density would decrease.
What happens to density if the volume increase?
must decrease
What law of gas decrease in temperature and decrease in volume?
Charles's Law
Are there any isomers of toluene?
Yes. Two isomers of toluene are known as toluene-2,4-diisocyanate and toluene-2,6-diisocyanate
