What happens to particles in a substance whe the sustance's temperature increase?
When the temperature of a substance increases, the particles within the substance gain energy and move more quickly. This increased movement causes the particles to spread out and the substance to expand. Additionally, the increased kinetic energy may lead to changes in the substance's state, such as melting or vaporization.
Why do substances expand when temperature is increased?
When the temperature of a substance is increased, its molecules or atoms jiggle faster and move farther apart, on the average. The result is an expansion of the substance. With a few exceptions, all forms of matter--solids, liquids, gases, and plasmas--generally expand when they are heated and contract when they are cooled.
What happens to the motion of an object's particles as their thermal energy increases?
They start to move faster, therefore, the reaction will happen quicker. This is because there is more chance of a collision between the particles.
Is celsius in reference to heat?
Celsius is a unit of temperature measurement based on the Celsius scale, which is commonly used in many countries around the world. It is not specific to heat alone but can be used to measure the temperature of any substance or environment.
How does temperature relate to the motion of particles?
as temperature increases the so does the motion of particles (meaning, they move faster when hotter) and also move slower when colder until they stop moving at negative -471 degrees aka absolute zero which has never actually been done.Temperature is the average kinetic energy of all the particles in an object. So yes, not only is it related to the motion of the molecules, but it is entirely determined by their average speed.
What is the name of the condition when the average velocity of atmospheric molecules around you is not zero?
The condition you are referring to is called temperature. Temperature is a measure of the average kinetic energy of the particles in a substance, such as air. When the average velocity of atmospheric molecules is not zero, it indicates that the substance has a non-zero temperature.

Does a change in temperature cause a change volume?
Temperature can be used as an indication of the energy that particles in a substance have. When the temperature is higher, particles have more energy and "bounce" around harder and in a bigger space. When the temperature is lower, the opposite happens.
Do temperatures mesure how fast the particles of a substance are moving around?
True... Technically, yes. The faster the particles move, the more heat they give off. So therefore, when we actually take a temperature, it is in theory, the measrue of the speed of the particles. Improvement: Temperature is defined as the average kinetic energy of the particles in a particular substance. Kinetic energy is associated with the speed of particles by KE=(1/2)mv2. Particles do not technically 'give off heat' when they move since by laws of thermodynamics heat is a transfer of energy between substances and the term does not apply in this circumstance.
When the particles of a substance move around faster what do they cause the substance to do?

How can a substance flow?
A substance can flow when its particles are able to move past one another. This typically occurs when the substance is in a liquid or gas state, allowing the particles to freely slide or flow around each other. Factors such as temperature, pressure, and molecular structure can influence how readily a substance can flow.
What happens to particles in a substance when its heated or cooled?
In a solid, the particles start to vibrate a lot.In a liquid, the particles begin to move around faster and faster.In a gas, the particles move extremely fast through the air.

Molecule of a substance are in a 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 happens to the motion of an object's particles as their thermal energy increases?
They start to move faster, therefore, the reaction will happen quicker. This is because there is more chance of a collision between the particles.
How would you describe the arrangement of particles as heat energy and temperature increase?
When you add energy to a substance in the form of heat, the energy is used to increase the motion of its particles. The more heat energy you add, the higher the temperature of the substance is, and the more the particles move around (vibrate, rotate, translate). In a solid, the particles have a relatively low amount of stored energy, and are arranged pretty close together in some kind of ordered fashion. As you add more heat and the temperature increases, the particles vibrate in place more and more, transferring this energy to one another as the collide. At some point, you may add enough energy so that the particles move enough to escape the forces keeping them together (mainly attractive forces between the particles). Escaped particles will then likely form a liquid, able to move around much more freely. Think ice melting into liquid water. These liquid particles can move around and rotate, bumping into one another. They are still fairly tightly packed, and the density of the substance is still quite high. If you keep adding heat and increasing the temperature of the liquid, the particles may have enough energy to move so fast that they can overcome the atmospheric pressure and change into a gas. Think liquid water boiling into water vapour (steam). These gas particles are now fairly far apart from one another (meaning a lower density substance), and move very quickly around in space. Their motion is pretty random, and it is these many random collisions that exerts pressure on surrounding surfaces. When you blow up a balloon, for example, it is the air particles constantly bumping into the inside of the balloon that keep it inflated.
Why does evaporation lowers the temperature of liquid?
In any liquid the particles are moving around at various different speeds. The temperature is a measure of the average speed. When a liquid starts to evaporate, it is because the most energetic particles leave the liquid and move away into the air. This means that the average speed of particles in the liquid is less and so the temperature is lowered. However, energy is soon absorbed from the surroundings.
