What type of energy makes up most of the internal energy of a solid substance?
The internal energy of a solid substance is primarily made up of kinetic energy of its atoms and molecules due to their motion and vibrations within the solid structure.
What is true for a substance that absorbs energy?
When a substance absorbs energy, its internal energy increases, which can lead to a rise in temperature, a change in phase (e.g., from solid to liquid), or chemical reactions. Absorbing energy typically causes the substance's particles to move more quickly or rearrange themselves in a way that stores the additional energy.
When heat is supplied to a solid substance what happens to the energy?
When heat is supplied to a solid substance, the energy is absorbed by the molecules, causing them to vibrate faster and thus increasing their kinetic energy. This increase in kinetic energy allows the solid to eventually change phase into a liquid or gas, depending on the substance and the amount of heat supplied.
In which state of matter would a substance have the least thermal energy?
The solid state.
Which change in state requires that energy be added to the substance?
Melting solid into liquid requires energy to be added to the substance.

Why heat is released by the particles of a liquid substance when it becomes a solid?
temperature has to be low so it can freeze. it has to release internal energy so it can be stable
What is the energy of a substance has from the movement of its particles?
solid
What type of phase change does a substance absorb energy from its surroundings?
When a substance absorbs energy from its surroundings, it undergoes a phase change known as endothermic. This results in an increase in the substance's internal energy, allowing it to transition from one state to another (e.g., from solid to liquid or from liquid to gas) by absorbing heat from its surroundings.

Why does solid sodium chloride melt when heated highly?
During heating the internal energy is increased, the ordering of the chemical entities in the crystal lattice is destroyed and the substance is melted.
In which state of matter would a substance have the least thermal energy?
The solid state.
What cause a substance to melt?
When a substance is heated, its internal energy increases and causes the particles to move more rapidly, breaking the bonds holding them in a solid state. This results in the substance transitioning from a solid to a liquid state, known as melting. The melting point is the specific temperature at which this transition occurs for a particular substance.
A solid form of a substance that has an orderly internal arrangement?
A crystal is a solid form of a substance that has an orderly internal arrangement. Crystals display a repeating pattern of atoms or molecules that extends in all directions, creating a geometric structure.
When a substance changes from a solid to a gas it needs to what energy?
gain heat energy.
How do you turn a liquid into a solid?
You freeze the substance! (You remove energy from the system.)
