What is the state of matter just before a substance melts?
The state of matter just before a substance melts is typically solid. As heat is applied, the solid absorbs energy and its particles begin to vibrate more rapidly until the intermolecular forces are overcome, leading to the melting phase transition.
Does a substance change mass if it changes physically?
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
During which state of matter does thermal energy of a substance increase?
The thermal energy of a substance increases when it changes from a solid state to a liquid state, or from a liquid state to a gas state. This is because the molecules in the substance gain more kinetic energy and move more freely as the substance transitions between states of matter.
Is anger matter or non matter?
Anger is a psychological and emotional response, so it is considered non-matter. It is a feeling or state of mind that does not have physical substance.
What state of matter describes a substance that has a definite volume and definite shape?
The state of matter that describes a substance with a definite volume and shape is "solid." In a solid, particles are closely packed and have strong forces holding them together, preventing them from moving freely.
What was liquid before liquid?
If a substance that exists in liquid state was not in liquid state then it was in its other states of matter namely solid, gaseous.
What state of matter is the substance in?
Solid
What happens at the molecular level when a substance boils?
When a substance boils, the intermolecular forces holding the molecules together are overcome by the heat energy. This allows the molecules to move more freely and escape as a gas. The temperature at which this occurs is the boiling point of the substance.
What is the state of matter just before a substance melts?
The state of matter just before a substance melts is typically solid. As heat is applied, the solid absorbs energy and its particles begin to vibrate more rapidly until the intermolecular forces are overcome, leading to the melting phase transition.
What state of matter is This Substance that boils at -123 degrees celsius and melts at -150 degrees celsius?
The substance is a gas because its boiling point is lower than its melting point, indicating that it transitions from solid to gas without passing through the liquid phase.
What are freezing?
The temperature at which a substance that is in a liquid state of matter turns into the solid state of matter.
Is the state of matter of a substance a chracteristic property?
There are three basic substance characteristics for matter and they are solid, liquid, and gas.
What is the state of matter in which the volume and shape of a substance are fixed?
the solid state
What is a state of matter in which the volume and shape of a substance are fixed?
the solid state
What is the state of matter in which the volume and the shape of a substance are fixed?
the solid state
When a substance from one state of matter to another it is called?
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
Does a substance change mass if it changes physically?
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
