What happens to the kinetic energy of molecules as you go from a gas to solid?
As you go from a gas to a solid, the kinetic energy of the molecules decreases significantly. In a gas, molecules move freely and possess high kinetic energy, allowing them to collide and spread apart. As the substance cools and transitions to a solid, the molecular motion slows down, leading to a reduction in kinetic energy. In a solid, molecules are closely packed and vibrate in fixed positions, resulting in much lower kinetic energy compared to their gaseous state.
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. Kinetic energy is the energy an object has due to its motion and is dependent on both its mass and velocity.
Do molecules move or possess motion?
Yes, molecules possess motion due to their thermal energy. This motion can manifest as vibration, rotation, or translation within the substance. The extent and type of motion vary depending on factors like temperature and molecular structure.
Does mind have kinetic energy?
No, the mind does not possess kinetic energy. Kinetic energy is energy that is created by a force or motion.
All the molecules of a substance possess the average kinetic energy value. True False?
True. In a substance, all molecules possess the average kinetic energy value because temperature is a measure of the average kinetic energy of the particles in a substance.
All the molecules of a substance possess the average kinetic energy value?
This statement is correct according to the kinetic theory of gases. The average kinetic energy of gas molecules is directly proportional to the temperature of the gas. This means that at a given temperature, all gas molecules will have the same average kinetic energy.
This is the measure of intensity of heat in degress reflecting the average kinetic energy of the moleness?
Temperature is the measure of intensity of heat in degrees, reflecting the average kinetic energy of the molecules in a substance. The higher the temperature, the faster the molecules move, and the more kinetic energy they possess. Temperature is typically measured in degrees Celsius or Fahrenheit.
What form of energy do molecules possess?
Molecules possess kinetic energy, which is the energy of motion.
What does temperature have to do with energy?
Temperature is a measure of the average kinetic energy of molecules in a substance. As temperature increases, the molecules move faster and possess more energy. This connection between temperature and energy is fundamental to understanding how heat flows and how thermal processes occur in various systems.
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.
Measure of the kinetic energy of the atoms of an object?
Temperature is a measure of the average kinetic energy of the atoms or molecules in an object. It reflects how fast the particles are moving and the amount of thermal energy they 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.
