Does waters polarity help it act as a universal solvent?
Yes. Its polarity allows it to dissolve other polar substances and many ionic compounds.
Why does heating up the solvent help dissolve the solute faster?
because the atoms expand causing it to evaporate
What energy and forces are used in the behavior of particles in each state?
plz someone help me for homework 'use energy and forces to explain the differences in behaviour of the particles in each state.' I don't get it so plz help soon :)
How does a thermometer help when comparing the energies of particles?
A thermometer measures the amount of thermal energy a material has. This thermal energy is related to the vibrational and rotational energy the particles in the material have. By using the thermometer to measure the temperature of a material you are, in effect, measuring the amount of energy the particles of that material have.
Does kinetic energy help sugar dissolve more quickly?
The kinetic energy is only very slightly involved in dissolving sugar. What is important is that stirring mixes the solution and the liquid close to the sugar will not get saturated because it is being mixed with all the other liquid. the grains of sugar will present more surface area to the solvent (they will be mixed up in it and not settle to the bottom of the mixing vessel) thus the grains will dissolve faster if they are stirred vigorously. The heat energy added to the solution from stirring plays a very minor role.
What is a strong liquid that can dissolve particles?
The most common solvent is water; the next-most common is ammonia. Often we add something to the solvent to help it dissolve things faster: * Any strong acid, such as HCl (hydrochloric acid), makes the solvent corrosive. * Any strong base, such as NaOH (sodium hydroxide), makes the solvent caustic. * a surfactant also helps the solvent dissolve particles faster.
Why grinding help a solution dissolve rapidly?
It increases the surface area of the solute that is exposed to the solvent.
How does a particle theory explain how a solute dissolves into a solvent?
You can use the particle theory to help explain what happens when solutes dissolve. The particle theory states that there are spaces between all particles. This means that, in a sample of water, there are many water particles, but also many empty spaces. When you look at sugar. The sugar dissolves, the sugar particles separate and mix with the water particles.
How does an increase in surface area help a solute dissolve more quickly?
Not necessarily just changing the surface area causes the rate to change. Changing the ratio of surface area volume changes the rate at which a solute dissolves in a solvent. If the surface area is larger and the volume of a solute is smaller or the same, then the rate at which the solute dissolves in a solvent increases. If the surface area is smaller and the volume of the solute is larger or the same, then the rate at which the solute dissolves in a solvent decreases.

Why do need to stir the water continuously during heating?
by heating we increase the inter moleculer space of the solvent so the solute particles get in the increased space and by stirring also the same purpoose is served . in short it is done so as to dissolve the solute in the solventHeating will help solutes dissolve in many solvents. For example salt will dissolve in hot water better than cold water.Many chemical reactions either require energy input to initiate a reaction, or they react better at higher energy levels.Endothermic reactions require energy to proceed.Even exothermic reactions may require activation energy to initiate the reactions.Or... many reactions won't run efficiently or completely at cold temperatures.

Energy is produced by the vibrations of electrically charged particles?
Light Energy. Happy to help you cheat ;)

What kind of household solvent will dissolve the adhesive from stickers and tape?
Nail polish remover will help in some casesANS 2 - Goo Gone or Lift -Off is best for that
