What happen to the atom or molecules of a substance when it melts?
The intermolecular forces are weakened.
When are molecules of a substance in motion?
Molecules of a substance are in constant motion. Whether you have a solid, liquid, or gas, the particles are moving (but the speed and amount they move differs). Particles of a solid move the least (they basically vibrate), particles of a liquid can flow around one another, and particles of a gas have a lot of space between them because they move in random, constant motions.
What is the origin of the thermal expansion?
As a substance warms up, the molecules within it become more energetic - vibrational, rotational and translational energies increase and the molecules push apart as they are able to exert more force on each other as they bang around faster and harder.
When a substance changes from a solid to a gas what happens to the speed of the molecules?
The speed doesn't change, it's just that the molecules are free to move around, rather than being restricted to a shape.
How do molecules expand?
Air expands due to high temperature water. And nothing happens to the molecules. As they move faster usually from increased temperature, they become farther apart.
How heating a substance affect that substance?
Heating a substance can result in a chemical reaction, which usually results in a simple combustion reaction. This is because Oxygen, or O2, is added to the substance, which can dramatically alter the substance.
What happens to the molecules of a substance when it is charring?
Normally, when substance burns, the molecules undergo a rapid oxidation, which excites the molecules greatly. The heat that is input into the substance, and the oxidation process, causes the molecules to move around very quickly. As the molecules return to their lower energy resting state, they shed the excess energy in the form of heat. When the goal is to char, instead of burn, the molecules are exposed to the same heat as for burning, but they are denied oxygen. Since the materials do not have access to oxygen, they do not burn (rapidly oxidize). All of the molecules still get excited, and move and bump into each other, but the fuel is not consumed, as that requires oxygen. Once the molecules of the substance get hot enough, any molecules of water or other liquids change state to a gas and are driven out of the substance being heated, because of the expansion of the gas. Charring is most commonly used to dry wood completely, without using up the wood's potential energy as fuel.
How does water change from one state to other?
As the heat is lost from the water substance, the H2O molecules lose energy and move around less. This makes the state change. It is also inversely true for when heat is gained. It adds energy to the molecules and they move around more.
When does a substance change from a solid to a liquid?
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
What happen to the atom or molecules of a substance when it melts?
The intermolecular forces are weakened.
What number do these decimals cluster around?
78.638
What will happen to the molecules or atoms of a substance when it melts?
the atoms will begin to giggle around more as they gain thermal energy.
How do you replace the cluster on a Toyota Echo?
you pull out the fram around the cluster then there are 2 screws you unscrew them and unhook from the wiring harness

Why does diffusion occur faster in hot water than in cold water?
This happens because the hotter a substance is, the faster its atoms or molecules are moving. They have more mobility and can get around faster.
How do you remove a 2001 Mercedes Benz S430 instrument cluster?
Purchase or borrow the Mercedes cluster removal keys 9 bucks on eBay, and place them in the slots on the side of the cluster and pull the cluster straight out. Takes 2 minutes Get the cluster repaired in the USA for around $250
What happens as the molecules in a liquid move around?
the molecules will go slowly around in the glass
