What two changes of state release energy?
There are actually three changes of state that release energy. Liquid to solid, gas to liquid, gas to solid.
What happens to the thermal energy of a substance during a physical change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
What happens to molecular energy when a substance changes states?
The molecular energy will usually increase or decrease, depending on the exact situation.
What is sublimaton?
Submilation is when you change something directly from a gas to a liquid, with out changing it into a liquid first.
What physical states is present when a substance melts?
what state of matter is present at the melting point of a substance
What change is melting consider because energy is gained by the substance as it changes states?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Changing phases is also a physical change.
What happens when a substance change states?
When a substance changes state, Energy within the substance is gained or lost, but the composition is unchanged.
When a solid changes to a liquid energy it is?
Melting. States of mater: Solid > Liquid > Gas > Plasma Low energy -----> High energy
How are states of matter and changes in energy related?
When thermal energy is added or removed, the state of matter changes to another eg. solid becomes liquid and liquid becomes gas.
What two changes of state release energy?
There are actually three changes of state that release energy. Liquid to solid, gas to liquid, gas to solid.

What happens to molecular energy when a substance changes states?
The molecular energy will usually increase or decrease, depending on the exact situation.
What are the Changes of state?
There are three main states that a substance can exist as: solid, liquid and gas. The transition between these states occur when a substance is heated or cooled past their freezing/melting or boiling/condensing points. Solid -> Liquid = Melting Liquid -> Gas = Boiling Gas -> Liquid = Condensing Liquid -> Solid = Freezing
What happens to the thermal energy of a substance during a change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing

Submilation is when you change something directly from a gas to a liquid, with out changing it into a liquid first.
What physical states is present when a substance melts?
what state of matter is present at the melting point of a substance
When does solid change to gas?
Remember, the three states of matter are solid, liquid and gas. Matter is solid, when it has the least amount of energy because its atoms and molecules are least active. As the energy level increases, the energized atoms and molecules need more room to bounce around, so the substance becomes less dense and changes from a solid to a liquid. More energy leads to more expansion, and the matter changes once again from a liquid to a gas. It changes by Being so hot. That's why when you boil a pot of water, it bubbles and steams.
