The solid molecules are tightly packed and have the strongest intermolecular forces.The gases are not at all tightly packed and have the weakest intermolecular force.

Is the density of gaseous substance likely to be larger or smaller then the density of liquid or solid substance at the same temperature and why?
Temperature in this instance will not affect density, but rather pressure. The density of the gas will be much smaller than the density of a liquid or solid of the same chemical because it is a gas. The formula for density is mass over volume, and a gas has no measurable mass, making the gas always less dense than the liquid and the solid.
Why does temperature remain constant during melting and boiling?
because of phase transtion i.e. from solid to liquid during melting and from liquid to vapour during boiling. so just to change over from one phase to the other heat is totally utilized.
What is a simple definition of evaporation?
evaporation is when a solid turns into a liquid at one definite temperature (the melting point) but a liquid turns into a gas over a range of temperature. the process by which liquid turns into a gas over a range of temperature is called evaporation
Phase of matter with definite shape and volume in which the particles are arranged in a regular repeating pattern?
No, a phase is a physical characteristic. The substance may or may not have definite shape and volume.
What happens to a substance during changes between a solid and a gas?
The molecules of the substance gain thermal energy as a result of which they vibrate more energetically. When the molecules have acquired enough energy they escape from the solid and enter the gaseous phase. Incidentally, there is no requirement for there to be a liquid phase between the solid and gas.
What makes a gas a gas and its not a liquid or a solid?
the particles bounce all over unlike a liquid or solid
Is diphenylmethane solid or liquid at room temperature?
Diphenylmethane is a liquid over 22 oC.
Is diphenylmethane a liquid or solid at room temperature?
Diphenylmethane is a liquid over 22 oC.
Is a snowman liquid solid or gas?
A snowman is a solid when it's done being built, and is a liquid when it melts away. The only time that it would turn gas was if you poured boiling water over it.
What do you do when you remove solid partickles from liquid?
vghfuso it does not boil over Save
What is the temperature at which a solid changes into a liqiud?
It depends on the solid. Solid ice turns to liquid water at 0 degrees Celsius. Solid Tungsten doesn't turn to liquid until it's over 3000 degrees Celsius.
What are the 4 phases that changes solid liquid gas and plasma?
There are five common state changes between the three common states of matter. They are melting (solid to liquid), freezing (liquid to solid), condensation (gas to liquid), evaporation (gas to liquid) and sublimation (solid to gas, gas to solid).
How can liquid change to solid?
Matter changes from a solid to a liquid at its melting point temperature. For water .i.e @ > 32°F ice melts to water. At this temperature there is enough energy in the molecule that the bonds that hold water as ice are broken. The atom's movement can no longer be restrained and this increase in motion results in a solid, ice becoming a liquid, water.
Why do you think does the atmosphere contain over half of all the air in the atmosphere?
solid and liquid
What advantages does mass spectrometry have over infrared spectrometry?
Mass spectrometry provides more structural information about the molecule.
Is coffee a solid liquid or a gas?
yes
Is mercury solid at room temp?
When Mercury is at any temp. Over -47 it will stay a liquid
