All the molecules of a substance possess the average kinetic energy value?
This is false not all the molecules of a substance possess the average kinetic energy value. Temperature increases as the average kinetic energy of a gas increases.
How does the kinetic theory explain Brownian motion?
The molecules are in a state of constant motion. The particles exert attractive force on one another. The particles possess kinetic energy due to their motion.
When does an object possess kinetic energy?
When it is moving.
What form of energy is flowing water possess?
Kinetic energy. What form of grammar do you possess?
What form of energy does wind possess?
kinetic Possibly heat if it's warm out

This is false not all the molecules of a substance possess the average kinetic energy value. Temperature increases as the average kinetic energy of a gas increases.
Are all the molecules of a substance possess the average kinetic energy value?
No. Some will randomly move faster, some slower. That's why the term "average" is used.
What is diffusion pushed by?
The kinetic energy that all molecules naturally possess.
What is push diffusion?
The kinetic energy that all molecules naturally possess.
Difference between threshold energy and activation energy?
THRESHOLD ENERGY(T.E) You consider any particular reaction. the molecules of the reactants must necessarily possess certain minimum value of kinetic energy for the collision with other reactant and to from product . this minimum energy that the reactant molecules should possess is known as threshold energy (T.E) ACTIVATION ENERGY (A.E) Do you think all the molecules will possess this particular minimum kinetic energy required to form products? obviously not. if you take the graph of no of molecules vs their kinetic energy graph, you will see that only few molecules possess this minimum kinetic energy. so for other molecules also to participate in the reaction you need to provide certain extra energy to them by some means which is known as the activation energy. (A.E) Now the question arises ,how to calculate the activation energy. suppose in a reaction the average kinetic energy of the molecules of reactant be 10Joules , threshold energy is 50Joules. so what energy should be supplied for all the molecules to react. this is nothing but T.E - Average kinetic energy i.e.,50-10=40Joules. this is what is known as activation energy so ACTIVATION ENERGY (A.E) THRESHOLD ENERGY (T.E) AND AVERAGE KINETIC ENERGY (K.E) ARE RELATED AS A.E=T.E - K.E
How does evaporation?
Evaporation is a spontaneous phenomenon. The molecules in the liquid possess kinetic energy. All the molecules donot possess the same kinetic energy. The molecules with higher kinetic energy are on the surface of liquids. They can readily overcome the intermolecular attractions and escape into the atmosphere. This phenomenon is known as evaporation. As the molecules with higher kinetic energy keep on escaping the whole kinetic energy of the liquid is lowered. Since energy is directly proportional to temperature. Thus evaporation causes cooling effect.
What us ways in which atoms ions or molecules move?
they are attracted to each other opposites attract in tight spaces

When is a body said to possess kinetic energy?
A body is said to possess kinetic energy when it is in motion.
Can liquids flow and why?
All the states of matter possess two things: kinetic energy and force of attraction. This is experienced between their molecules. Liquids possess high kinetic energy which enables them to flow, while the force attraction between their molecules is weak so their molecules are free to move which enable liquids to flow. ----- Edit ----- Yes, liquids can flow because they don't have strong intermolecular bonds.
When you run around a trak do you possess kinetic or potential energy?
kinetic energy
