What is the total amount of energy a substance contains?
it is thermal energy
What does a mole measure?
An instrument can not be used to measure moles because moles is the amount of grams of a substance divided by the molar mass of the substance. This can not be measured and has to be calculated.
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 is the unit for the amount of chemical?
The SI unit for "amount of matter" is the mole, defined as that quantity of a substance that contains as many elementary units (atoms or molecules, depending on what the substance is) as there are atoms in precisely 12 grams of carbon-12.
Measurement of average amount of motion of molecules is?
The average amount of motion can be determined by the average speed or velocity of an object. The average speed can be calculated by the total distance divided by the total time. Speed is a scalar quantity. The average velocity can be calculated by the total displacement divided by the total time. Velocity is a vector.
What is the amount of particles in a substance?
semi-permeable
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 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.
The si base unit used to measure the amount of a substance whose number of particles is the same as the number of atoms of carbon in exactly 12 g of carbon-12?
Mole
Is the average amount of energy of motion in the particles of a substance?
Thermal Energy
What is the total amount of energy a substance contains?
it is 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.
How is temperature differ from thermal energy?
Thermal Energy is theTOTAL Ek of atoms in a substance.Temperature is the measure of the AVERAGE Ek of the atoms in a substance.Thermal energy: The total amount of kinetic energy contained in all the particles of a substance. The greater the kinetic energy of the particles in the substance, the more thermal energy the substance has. But thermal energy also depends on the number of particles in a substance. The more particles a substance contains, the greater its thermal energy.Temperature vs. Heat :When you think of temperature, you probably think "hot" or "cold." To scientists, temperature is a measure of the average kinetic energy of the particles in a substance. The more kinetic energy the particles have, the higher the temperature of the substance. Unlike thermal energy, however, temperature is not affected by the number of particles the substance contains.(Taken from: Sciencesaurus A Student Handbook Pp. 301-302)
Define internal energy?
Total amount of kinetic energy and potential energy of all the particles in a substance.
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 :)
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.
