Explain in terms of particles why energy must be given to a liquid if it is to be changed to a gas?

Well, basically, a gas is a lot less dense than a liquid. The particles spread out more freely and move a lot faster. It obviously takes energy for this occur.

Heat is removed from a gas and the substance becomes a liquld how can you explain this?
The particles in a liquid have less kinetic energy than the particles in a gas.
Which are the first particles to evaporate from a liquid?
The particles that evaporate from a liquid are on the surface of the liquid.
How does sound travel in solid liquid and in gas . explain?
Sound travels by particles (such as atoms or molecules) bumping into other particles, thus transferring the energy, in form of a sound.
What has to be overcome for a solid to change to a liquid and a liquid to a gas?
The energy between particles. The particles must be heated so that there is no forces of attraction, therefore the solids particles can loosen into liquid particles and the liquids particles can loosen into gas, the heat energy is used to make the particles move faster
Which answer lists the subtances in order from greatest energy of particles to least energy of particles?
Gas, Liquid, Solid

What happens to substance during changed between liquid and gas?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
Which are the first particles to evaporate from a liquid?
The particles that evaporate from a liquid are on the surface of the liquid.
What happens to particles of a liquid as the liquid boils?
the particles are given more energy.
Use the particle theory to explain the expansion and contraction of a solid when temperature is changed?
The expansion and contraction using particles is when a liquid melts because the particles get more energy and move around so making the substance appear less then there is and when the particles cool down they loose energy and move around slower so making them appear bigger than when they were warmer.
How does sound travel in solid liquid and in gas . explain?
Sound travels by particles (such as atoms or molecules) bumping into other particles, thus transferring the energy, in form of a sound.
When comparing a solid with a liquid which has particles with more energy?
Liquid
How is the energy in a liquid?
The energy is slow ; particles are close together
What has to be overcome for a solid to change to a liquid and a liquid to a gas?
The energy between particles. The particles must be heated so that there is no forces of attraction, therefore the solids particles can loosen into liquid particles and the liquids particles can loosen into gas, the heat energy is used to make the particles move faster
How does the movement of particles in a liquid help to explain the shape and volume in a liquid?
Because its particles are free to move, a liquid has no definite shape. However, it does have a definite volume.
Which answer lists the substances in order from greatest energy of particles to least energy of particles?
Gas, liquid, soil
Which answer lists the subtances in order from greatest energy of particles to least energy of particles?
Gas, Liquid, Solid
