What is the energy needed for a substance to change from liquid state to a gaseous state?
thermol
When a substances is heated what happens?
When a substance is heated, its temperature increases and the kinetic energy of its particles also increases. This causes the particles to move faster, leading to increased collisions and interactions among them. Eventually, the substance may undergo physical or chemical changes depending on the temperature and nature of the substance.
What happens to a substance as its thermal energy increases?
As thermal energy increases, the substance's particles move faster, leading to an increase in temperature. Eventually, the substance may undergo a phase change (e.g., melting or boiling) or undergo chemical reactions if the increase in energy is significant enough.
What happens to the kinetic energy of the particles in the substance during process condensation?
The average kinetic energy of the particles falls.
What happens to molecular energy when a substance changes states?
The molecular energy will usually increase or decrease, depending on the exact situation.
How is the temperature of a gaseous substance related to the average kinetic energy of the particles in the substance?
if the temperature of the substance is raised then the kinetic energy of the gaseous particles will also increase....
What happens to the particles of a substance as you take energy away?
As energy is taken away from a substance, the particles within the substance slow down and lose kinetic energy. Eventually, the particles may form a solid structure as they come closer together due to the reduction of thermal energy.
What is the energy needed for a substance to change from a liquid state to a gaseous state?
thermol
What happens to substance during changed between liquid and gas?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
What happens to substance during changes between gas to liquid?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
When freezing happens is energy added?
No, in freezing, energy is actually removed from a substance. As the temperature drops, the molecules within the substance slow down and come closer together, eventually forming a solid state. This process releases energy in the form of heat.
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.
Does a substance gain o lose thermal energy when it evaporates?
A substance gains thermal energy when it evaporates, as energy is required to break the intermolecular forces holding the molecules together and allow them to escape into the gaseous phase.
How much energy released by dihydrogen in gaseous state?
The energy released by dihydrogen in its gaseous state would depend on the reaction it undergoes. When dihydrogen reacts with another substance, such as oxygen, the energy released is a result of the bond formation in the products. This energy can be calculated using methods like calorimetry.
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
What is the energy needed for a substance to change from liquid state to a gaseous state?

What change of state happens when something vaporizes?
what change of state happens when something melts
