What is the random molecular of a substance is greatest when the substance is?
It is greater when the substance is at a higher temperature. This is because the mean square speed of the molecules of a system is proportional to thermodynamic temperature.
Is Boiling is the maximum temperature a substance can reach?
No. Once the substance crosses into steam the steam temperature can rise much higher than boiling.
A pure substance boils only at a certain temperature?
Each liquid boils at a different temperature, but the temperature it boils at is called the Boiling Point. For example, the boiling point of water is 212 Fahrenheit.This specific temprature is dependant on the pressureon the liquid at that time, as an example at ahigher temperatures the boiling point is higher.
What is the process where pollution levels increase through the food chain?
increase in concentration of a pollutant from one link in a food chain to another. Biomagnification is the bioaccumulation of a substance up the food chain by transfer of residues of the substance in smaller organisms that are food for larger organisms in the chain. It generally refers to the sequence of processes that results in higher concentrations in organisms at higher levels in Biomagnification: the food chain (at higher trophic levels). These processes result in an organism having higher concentrations of a substance than is present in the organism's food. Biomagnification can result in higher concentrations of the substance than would be expected if water were the only exposure mechanism. Accumulation of a substance only through contact with water is known as bioconcentration..
Does KCl have a higher boiling point than CO2?
KCl is an ionic substance (strong intermolecular forces) and CO2 is a non-polar covalent substance (weak intermolecular forces)
Materials of low mass are fused together to form a substance of higher mass during what?
Combining lighter atoms to produce heavier atoms is called fusion.
Materials of low mass are combined to form a substance of higher mass during what?
fusion
What is a Diffusion is the movement of a substance?
diffusion is the movement of materials into cell membranes when the outside of the cell has a higher density than the inside
Does an increase in pressure results in a higher melting temperature of a dry substance?
yes because it stays together
When using the particle model of matter to describe what happens to the density of a substance when it cools?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
What is the cell process called when a higher concentration of substance is outside the cell?
Exo-osmosis
What is the quality of substance that describes how it appears or behaves?
The measure is called 'electronegativity". The higher the electronegativity, the higher it's ability to react.
What does a substance gain or lose when its temperature changes?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
What is low pH and what happen to meat?
The lower the pH of a substance, the more acidic it is. Materials with higher pHs are more basic.I cannot answer the meat portion of this question.
What is the movement of a substance from an area of high concentration to an area of low concentration?
passive transport Movement down a concentration gradient is known as diffusion.
Substance present in smaller amount in a mixture?
The substance in a solution that is present in the smaller amount is called the solute. The substance that has a higher amount is called the solvent.
Does temperature have a higher amount of thermal energy in a substance?
The higher of the temperature of a substance, the more thermal energy it has.
