What else can I help you with?
What are 3 different chemical changes?
-Irreversible -Gas is produced -A Precipitate (solid leftover) is formed -Energy (light, heat, etc..) is given off -A change in colour
What is unique about temperature during phase changes?
It doesn't change notwithstanding heat energy changes.
The addition or loss of thermal energy changes the arrangement of the particles during what?
a change of state
During an energy change?
During an energy change, the energy of a system is converted from one form to another, such as from potential to kinetic energy. This transformation can occur through various processes, including work done by external forces or heat transfer between the system and its surroundings. The conservation of energy principle states that the total energy of a closed system remains constant during these changes.
What happens during state of change?
Kinetic Energy is gained in the foward changes and lost in the reverse changes of state
What are he cHANGES THAT PLACE INSIDE THE MATTER DURING THE CHANGE OF STATE?
The thing that changes during a change of state is the intermolecular forces are disrupted. The temperature will not change because all of the energy is going into disrupting or organizing the intermolecular forces.
In a chemical change energy does what?
In a chemical change, energy is either absorbed or released. This can result in changes in temperature, light production, or other forms of energy transfer during the reaction.
During which three changes of state is energy absorbed?
cchemical change and energy change also the change of a gas to a liquid
Why are some things reversible and irreversible?
Some physical and chemical processes are reversible, meaning they can occur in both directions, while others are irreversible because they involve a change that cannot easily be undone. Reversibility is influenced by factors such as energy input, enthalpy changes, entropy changes, and the presence of catalysts that can facilitate reversibility. Irreversible processes often involve a substantial increase in entropy or the formation of stable products that are difficult to break down.
Is chemical energy related to chemical change?
Yes it is released/ absorbed during chemical changes.
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.
Do physical changes involve change in energy?
Yes, physical changes involve a small change in energy.
