What is the total kinetic energy of a substance atoms?
The total kinetic energy of a substance's atoms is the sum of the kinetic energies of all the individual atoms in the substance. It is a measure of the overall motion of the atoms within the substance.
What happens to a substance when the space between the substance's particles increases?
When atoms are separated the substance changes forms. Solid Liquid Gas Plasma These are a few of the forms. The substance becomes more fluid, more easily shaped and compressed. It is able to form new materials, and is easier to ignite.
What happens to the atoms in a liquid as it freezes?
As a liquid freezes, the atoms in the substance will slow down and come closer together, forming a crystalline structure. This process releases energy in the form of heat. As the temperature decreases further, the atoms become locked into fixed positions within the crystal lattice, resulting in the solidification of the substance.
A measure of the average kinetic energy of the atoms in a substance is?
Temperature is a measure of the average kinetic energy of atoms in a substance. The higher the temperature, the greater the average kinetic energy of the atoms.
How does energy changes as a substances?
Energy can change when a substance undergoes a phase change (such as melting or vaporization) or a chemical reaction. During these processes, energy is either absorbed (endothermic) or released (exothermic) as the internal structure of the substance changes. This energy change is due to the breaking or forming of bonds between atoms, resulting in a change in the overall energy content of the system.
What happens when a clear substnace undergoes a chemical change?
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
A substance that undergoes change in a chemical reaction is called a what?
A substance that undergoes change in a chemical reaction is called a reactant. Reactants are the starting materials in a chemical reaction that are transformed into products through the rearrangement of atoms.
What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
What does the composition of a substance does not change?
The composition of a substance remains constant if the chemical bonds that hold the atoms together are not broken. This means that the types and numbers of atoms present in the substance do not change, even if it undergoes physical changes like melting or boiling.
When a substance undergoes a physical change what does not a change?
The chemical make up of a substance does not change. It must remain the same combination of atoms or molecules to be considered only a physical change.
What happens to the energy content of a fuel as the number of carbon atoms increases?
In this case the heat of combustion decrease.
When the substance undergoes a chemical change its identity deos not change?
That's correct. In a chemical change, new substances are formed through rearrangement of atoms, but the identities of the original atoms remain the same. This is because atoms are not created or destroyed during chemical reactions, they simply rearrange into new combinations.
What process happens when a substance undergoes a chemical change?
During a chemical change, the substance's chemical composition is altered, resulting in the formation of new substances with different properties. Bonds between atoms are broken and rearranged to form new molecules. This process is typically accompanied by the release or absorption of energy.
What happens to the atoms of a substance that is negatively charged?
Because the sun is the center of the solar system.
What happens to atoms in fuel?
Atoms in fuel undergo chemical reactions such as combustion when exposed to heat, resulting in the release of energy in the form of heat and light. During combustion, bonds between atoms are broken and reformed, leading to the conversion of chemical potential energy in the fuel to thermal energy.
What happens when gain of oxygen takes place?
During gain of oxygen (oxidation), a substance loses electrons or gains oxygen atoms. This process typically results in an increase in oxidation state and a loss of hydrogen atoms. It is commonly associated with the production of energy in cellular respiration and combustion reactions.
What happens to the atoms or molecules of a substance when it boils?
the atoms and molecules will vibrate, causing the substance to heat up (friction causes heat, the molecules and atoms will rub together, causing friction). I hope this helped!!!!!n_n when a substance reaches its boiling point naturally the intermolecular force becomes weak and the substance gets converted from one form to another..
