Does air weighs less than an equal amount of solid or a liquid?

Particles come in many, many shapes and sizes, and can be solid particles or liquid droplets. The size of particles is directly linked to their potential for causing heath problems. Traditionally, the environmental sciences have divided particles into two main groups and these two groups are different in many ways. PM10 is particles between 2.5 and 10 microns (micrometers) in diameter (a human hair is about 60 micron in diameter). PM2.5 is particles smaller than 2.5 microns. The PM10 and PM2.5 measurements you might have seen reported, by the EPA for example, refer to the total weight of the particle found. This is a holdover from when the available technology had difficulty detecting individual particles. More modern monitoring equipment, such as that used in clean room monitoring, count and size individual particles. The Dylos DC1100 is this more modern type of device and counts individual particles in two size ranges which will roughly correlate to PM2.5 and PM10.
There is more than size that is different in these types of particles. Each type of particle has different material compositions and can come from different places. The smaller the particle the longer it can remain suspended in the air before settling. PM2.5 can stay in the air from hours to weeks and travel very long distances because it is smaller and lighter. PM10 can stay in the air for minutes to hours and can travel shorter distances from hundreds of yards to many mile because it is larger and heavier ...

How can you tell if the rate of evaporation equals the rate of condensation?
When the rate of condensation of the gas becomes equal to the rate of evaporation of the liquid or solid, they are said to be in an equilibrium state. The amount of gas, liquid or solid no longer changes in this state.
What is the difference between solid liquid gases in mass?
Nothing, if it is the same amount of material in all three phases.If however it is the same volume and pressure then solid and liquid phases will have about equal mass but the gas phase will have much less mass.
What does the latent heat of fusion represent?
The energy required to melt a substance. (Apex)
When a substance freezes what causes the liquid phase to change into the solid phase?
When a liquid is cooled, the average energy of the molecules decreases. At some point, the amount of heat removed is great enough that the attractive forces between molecules draw the molecules close together, and the liquid freezes to a solid. Microscopic view of a liquid. Microscopic view of a solid. The temperature of a freezing liquid remains constant, even when more heat is removed. The freezing point of a liquid or the melting point of a solid is the temperature at which the solid and liquid phases are in equilibrium. The rate of freezing of the liquid is equal to the rate of melting of the solid and the quantities of solid and liquid remain constant.
When solid and liquid phases are in equilibrium which phase solid or liquid contain the greater amount of energy?
The answer depends on the specifics of the question. The idea though, is that when they are in equilibrium, both the solid and the liquid should have the same amount of energy PER MOLECULE. The fact that there is a solid component and a liquid component means that either the solid is melting or the liquid is freezing. In most situations, that means that the temperature of the whole mixture is constant. Another idea is that the energy in the molecules can either be kinetic or potential energy. Basically, the more kinetic energy PER MOLECULE an object has, the higher the object's temperature. Furthermore, the more potential energy PER MOLECULE that the object has, the further apart the molecules are from each other. Combining these ideas, here are a few possible answers to your question. 1. There is more solid than liquid. On average, the solid's molecules have the same kinetic energy as the liquid. The solid, having more molecules, has more kinetic energy total. The liquid has more potential energy in total. The solid has more overall energy. 2. There is more liquid than solid. On average, the liquid's molecules have the same kinetic energy as the solid. The liquid, having more molecules, has more kinetic energy total. The liquid also has more potential energy in total. The liquid has more overall energy. 3. There are equal amounts of liquid and solid. On average, the liquid's molecules have the same kinetic energy as the solid. The liquid has equal kinetic energy as the solid due to the even split. The liquid also has more potential energy in total. The liquid has more overall energy. These three are the main possibilities, and as can be seen in the details, the answer depends on the relative amounts of liquid and solid.
What is the amount of heat to change liquid into solid at constant temperature?
To change a liquid into solid at constant temperature, an amount of heat is released equal to the latent heat of that liquid. For water it is about 80 calories per gram.
Does 1 pound of liquid equal 1 pound of solid?
The pound is a unit of weight, so anything that weighs one pound, regardless of whether it is a solid, a liquid, or anything else, has the same weight.
What is the difference in mass between a solid and a liquid?
A solid and liquid have the same mass if the amount is the same.
Why does solid body weigh more in air than when immersed in a liquid?
the buoyant force of the liquid on the solid is more than the buoyant force of the air on the solid.

What does the latent heat of fusion represent?

What weighs more a pound of solid or a pound of liquid?
they both weigh one pound
A measure of how much of a solid will dissolve?
A measure of how much solid will dissolve in a given amount of liquid is known as the "solubility" of that compound in that liquid.

What does latent heat of fusion represents?
The amount of heat energy required to solid substance solid into a liquid state without any changes in temperature ______________________ Apex: The amount of energy required to turn a mole of a solid into a liquid
Why is it that when a solid dissolves in a liquid the mass of the solution that is made is the same as the mass of the solid added to the liquid?
this is because the amount of solute in the solution will have the same number of moles as that of the solid.
