Kinetic energy is the energy of a substance due to its motion. So, when we increase the temperature of substance then there will be increase in motion of particles.

Therefore, they will gain kinetic energy with increase in temperature.

Also, it is known that kinetic energy is directly proportional to temperature through the relation as follows.

You are watching: Which factor is defined as the average kinetic energy of a substance?

K.E = Thus, more is the temperature more will be kinetic energy of a substance. Hence, we can conclude that the temperature of the substance is the factor which is defined as the average kinetic energy of a substance.

What are the forces that create electromagnetism?
Maru <420>
The mslsec.com iselectromagnetic forces. They can beproduced by electromagnetic fields, electrostatic field, and magnetostaticfield. This force affects everything in the universe because it has an infiniterange just like gravity. The electromagneticforce is also a result of intermolecular forces between individual atoms andmolecules in matter.

A student weights out 635.94 g Na2CO3 and dissolved it in 2.0 L water. What is the molarity of his solution?
Mariulka <41>

You have to find out the number of moles of the substance.

I will use rounded numbers for the atomic weights because every periodic table is different.

2Ca = 2 * 40 = 80

1 C = 1 * 12 = 12

3O = 3 * 16 = 48

Atomic Mass = 140

moles = given mass / molar mass

moles = 635.94 / 140

moles = 4.54

=========

Now you need to find the concentration

C = moles / Volume in liters.

C = 4.54/ 2.0 L

C = 2.27 moles / L

Technically since the volume is only 2 significant digits, your mslsec.com should be 2.3 moles / L

If you do not have this as a choice, what are your choices.

A scientific theory is best defined as
olga55 <171>

mslsec.com:

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed, preferably using a written, pre-defined, protocol of observations and experiments.
