Water at 293K =20 oC Liquid at room temperature, density = 0.998 kg/L
Water at 277K = 4 oC Liquid near freezing to ice, density = 1.000 kg/L
Water at 268K =-5 oC Ice near melting to water, density = 0.917 kg/L
yes
There is no chemical difference, the only difference is the speed in which the molecules of the substances move. Slower molecules can be solid or liquid and very high speed molecules can be gas.
The transition state
Mercury is the only metal that is a liquid at room temperature, despite it's high density.
Heat is the speed of the particles the higher the speed the higher the heat. Density or state of matter is the distance between the particles the closer the particles the higher the density, the density of the particles determines the state of matter here they are from most dense to least dense; Solid, Liquid, Gas, and Plasma. the temperature (heat) of a substance can also determine the state of matter a substance is with higher heat at lower densities. PS the density/state list does not apply to water. PS Quantum state is not currently an official state yet, it would be the most dense and at the lowest temperature.
yes
The density of water is 1 and it is a liquid.
Any chemical difference exist.
Phase has nothing to do with chemical composition.
Boiling Point Elevation
Liquid state, nearest to freezing.
Vaporization is the conversion of a solid or liquid into a gaseous state. Evaporation is a type of vaporization, where liquid is converted to a gaseous state where the environment is not saturated.
Yes.It is because, distance between atoms in liquids is less than that in the gases.density is inversely proportional to the distance between the atoms.
Matter has more density when solid than when in a liquid state. The atoms are closer together.
as density is equal to mass per unit volume. for any substance, volume does not remain same in its three(solid, liquid and gas) state. so density vary when volume changes for different states of a substance
liquefaction-change from solid to liquid state condensation-change from gas to liquid-just opposite of evaporation
The difference will be in their physical state i.e., solid and liquid state and in their chemical composition. Solid fuels that are used are the filling inside bombs i.e,. gun powder. Liquid fuels used are RDX etc.
