What effects does an energy change have on the idenitity of a substance?
An energy change does not alter the identity of a substance. It may cause a physical change (like melting or boiling) or a chemical change (like reactions), but the substance itself remains the same at the molecular level. The energy change only affects the arrangement or movement of particles within the substance.
If enough energy is added to matter in the liquid state it will change into a different state during this change of state the particles would?
transition from a disordered arrangement in the liquid state to an ordered arrangement in the solid state, or to a more chaotic arrangement in the gas state. The particles gain or lose energy during this change, leading to alterations in their speed and spacing.
Which form of energy depends on both the motion and the arrangement of particles that make up matter?
Mechanical energy depend on motion and height. For example- a flying bird.
What causes a reaction in particles?
Particles can react with each other when they collide and exchange energy or change their arrangement of atoms. The nature of the reaction is often determined by the types of particles involved, their energy levels, and the conditions of the environment. Various factors, such as temperature, pressure, and concentration of particles, can influence the likelihood and outcome of reactions.
How would you describe the change in the arrangement of particle as heat energy and temperature decrease?
As heat energy decreases and temperature decreases, particles slow down and move closer together. This results in a decrease in the overall volume of the substance as the particles lose kinetic energy and exhibit less movement. The arrangement becomes more ordered and structured due to the reduced thermal agitation.
The addition or loss of thermal energy changes the arrangement of the particles during what?
a change of state
How would you describe the change in the arrangement of particles as heat energy and temperature increase?
When heat is added, the arrangement of the particle (the Entropy of the system) will become more disorganized and Entropy will increase. When heat is taken away, the arrangement of the particles will become more organized and Entropy will decrease.

What is energy mean?
Potential energy refers to the energy arising from the arrangement of a system of objects (particles), which interact with each other. Here, interaction means that objects apply force on each other. A change in the arrangement brings about a change in the forces interacting on the objects and the associated potential energy.
Where does the potential energy of the particles in an object come from?
The potential energy of particles in an object comes from the arrangement or configuration of these particles within the object. This energy is related to the forces of attraction and repulsion between particles, as well as the interactions between particles and their surroundings. As particles move within the object, their potential energy can change based on their position and the forces acting on them.
What type of energy is primarily associated with the random motion and arrangement of the particles in a substance?
Thermal energy is primarily associated with the random motion and arrangement of particles in a substance. It is a form of kinetic energy that results from the movement of particles at the microscopic level.

Why do material change size when they change temperature?
When materials change temperature, the kinetic energy of their particles changes, causing them to vibrate more or less vigorously. This vibration affects the spacing between particles, leading to expansion or contraction of the material. In solid materials, this change in spacing manifests as a change in size.

Mechanical energy depend on motion and height. For example- a flying bird.
What occures when particles in a gas lose enough thermal energy to form a liquid?
When particles in a gas lose enough thermal energy to form a liquid, they undergo a phase change called condensation. During condensation, the particles come closer together and transition from a disordered arrangement in the gas phase to a more ordered arrangement in the liquid phase. This process releases energy in the form of heat.
What changes is the arrangement of the particles and their energy?
Heat Capacity and Specific Heat CapacityThe amount of of temperature change, when thermal energy is added to the particles is another property that particles in different materials have. Different materials will increase or decrease their average energy depending on how much thermal energy is provided.Heat Capacity is the amount of thermal energy that warms or cools an object by 1oC (it depends on the mass and the type of particle the object is made of).Specific Heat Capacity is the amount of thermal energy that warms or cools 1 gram, of a specific type of particle, by 1oC.Changes of StateSome substances like water (or wax) can undergo observable changes through all three states of matter - solid liquid and gas.Some substances, like hydrogen, require high pressures and low temperatures (-253oC) to make the particles slow down enough for them to change their state from a gas to a liquid.Any pure substance can exist in all three states of matter.Melting and Boiling Points When heat is transferred in a space the average energy of the particles - the temperature of the substance - is affected, by increasing or decreasing. A substance will change it's state when it reaches certain temperatures - called boiling and melting points. Table 3 (p. 221) At everyday temperatures on Earth, most substances are either gases or solids.What Happens When A Liquid Evaporates? In a liquid, the particles are moving very quickly. At the surface, some of the particles are able to escape into the air, while others do not have enough energy to escape and remain in the liquid. As high energy particles escape, the average energy of the remaining particles is less and so the liquid cools. The cool liquid then cools the surface on which it is resting. This is called evaporative cooling. It is common and useful in many situations:Joggers cooling down as their sweaty clothes dry outWater cools down a roof on hot summer dayA wet cloth is placed on your forehead when you have a feverWhy The Temperature Stays The Same During a phase change, the average energy of the particles remains the same, but, the particles are rearranging themselves. Particles become less organized as their energy increases, so the substance changes from a solid to a liquid to a gas. As the energy of the particles becomes less, the particles rearrange themselves more orderly, so a gas changes to a liquid and then to a solid. The total energy of the particles changes - by increasing or decreasing, because the particles are not increasing or decreasing their speed, just their arrangement. The average energy doesn't change. The energy change is hidden from a thermometer and is called 'hidden heat' or 'latent heat'.
