Different substances have different boiling points. Distillation is the chemical process created to take advantage of this property. Cooling one side, the top of the column and applying a heat source to the bottom ensures lighter or more volatile substances accumulated at the top end of the column, assuming there is a constant flow with relative constant composition feeding the Distillation column, and an accumulation of less volatile material in the bottom.

Why does the substance in the column of the thermometer go up when it is heated?
When the substance in the column of a thermometer is heated, its temperature increases. As the temperature increases, the particles in the substance move more energetically and spread out, causing the substance to expand and rise up the column. This expansion is what causes the fluid to rise and indicate a higher temperature reading on the thermometer.
What has a effect on water density?
Temperature, salinity, and pressure have significant effects on water density. As temperature increases, water density decreases because warmer water molecules are more spread out. Higher salinity increases water density since dissolved ions make the water heavier. Pressure also impacts density, with deeper water being denser due to the weight of the overlying water column.
What is the difference between single column and column suppressor ion chromatography?
Single column depends upon small differences in conductivity between sample ions and elutent ions. Suppressor based ion exchange has a second ion exchange column, (suppressor) after the original ion exchanger that converts ions to a limited charged product.
Joule Thomson effect is temperature dependent or not?
The Joule-Thomson effect is temperature dependent. It describes the change in temperature of a gas as it expands or is compressed without doing external work. If the gas undergoes adiabatic expansion (no heat exchange with surroundings), its temperature will change depending on its initial temperature, pressure, and the nature of the gas.
What is mean by isothermal in gas chromatography?
Isothermal in gas chromatography means that the temperature of the column is kept constant during the analysis. This helps to maintain consistent separation of the analytes as they pass through the column, allowing for accurate and reproducible results.
In windows the number of pixcels in row and column is called?
resolution
How increase the resolution between two peaks in high pressure chromatography?
Resolution indicates the actual degree of separation of two compounds. - It can be increased by;- increasing column length ( diffusion will increase proportionally , opposing resolution) - altering selectivity of the column, (mobile and stationary phases). also gradient elution.
What is the effect of detector temperature on retention time?
Compounds injected onto a column interact with the column material. Some compounds "stick" to the column more than others. These compounds then have a long retention time. Heating increases the kinetic energy of the compounds on the column. This increased energy allows the molecules to wiggle free from the column more easily. So heating reduces the "stickiness" of the molecules. Since molecules will "stick" less, they will move more quickly through the column, and their retention times will decrease.

What is resolution of a thermometer?
The resolution of a thermometer refers to the smallest interval or increment between temperature readings that the thermometer is capable of measuring. It indicates the level of detail or precision with which temperature can be recorded. A higher resolution thermometer will be able to detect smaller changes in temperature compared to a lower resolution thermometer.
Which part of the water column is the saltiest?
Surface water has the highest salinity, however it is also the warmest, and because temperature has more effect on the density than the salinity, it rises to the top.
What are synonyms for backbone?
spinal column, spine, vertebrae, strength of character, resolution, nerve, daring, courage, determination
Why does the substance in the column of the thermometer go up when it is heated?
When the substance in the column of a thermometer is heated, its temperature increases.

This expansion is what causes the fluid to rise and indicate a higher temperature reading on the thermometer.
Is a higher resolution on a thermometer better?
A higher resolution on a thermometer means that it can measure smaller changes in temperature, which can be useful in certain situations where precise temperature readings are needed. However, for general household use, a standard resolution thermometer would be sufficient.
Does temperature effect plastic?
yes, temperature does effect plastic if it gets to hot it can melt it.
What is the effect of temperature on the effect of evaporation?
Rapid evaporation helps reduce the temperature of water.
How does the temperature change as you go up the fractionating column?
it goes up in 3's
