Why do we find it useful to have two units of the amount of substance the kilogram and mole?
When we are concerned with the number of particles than we use Mole as the unit of amount of substance because one mole of a substance contains the equal number of particles (i.e., 6.022×10^-23)Butin case when we are concerned quantity of matter we use the unit Kilogram.
What becomes bigger in size due to movement of particles in a solid?
If the particles in a substance are moving, the volume of that substance becomes larger because the particles move faster and spread farther appart. the mass of the object stays the same because it is the same amount of particles, just in a format in which the volume is larger. hope i helped :)
Does each substance has particles?
tiny particles
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 happens to the particles when the substance changes shape?
yes! particles of a substance assume different shapes and sizes
What is the average amount energy of motion in the particles of a substance?
temperature
Is the average amount of energy of motion in the particles of substance?
The average amount of energy of motion (also known as kinetic energy) in the particles of a substance (atoms and molecules) is measured by the temperature of that substance. More energy will produce a higher temperature.
Is the average amount of energy of motion in the particles of a substance?
Thermal Energy
How does temperature happen?
Temperature is a measure of the kinetic energy of the particles in a substance. Temperature in Kelvin is proportional to kinetic energy of particles. Heat on the other hand depends on the amount of substance present.
Define internal energy?
Total amount of kinetic energy and potential energy of all the particles in a substance.

What is the average amount energy of motion in the particles of a substance called?
A measure of the average kinetic energy of the molecules of a substance or object is simply it's Temperature! Hope that helps.
What is the average speed of the particles of a substance?
The average speed of the particles in a substance is the definition of temperature.
Does each substance has particles?
tiny particles
What is an attraction between particles of the same substance called?
An attraction between particles of the SAME substance is called cohesion.
Which term is defined as a measure of the energy of motion of particles in a substance?
Heat is a measure of the amount of energy due to the motion of the particles in a gas, liquid, or solid. Temperature is a measure of the average amount of heat energy in a given body.
