When a substance changes from a solid to a liquid and vice versa, its density changes.
What else can I help you with?
How does what happens to the particles in a substance during melting differ from what happens in freezing?
Its the degree of attachment between the molecules of the substance: frozen (solid) the arrangement is fixed. melted (liquid) the arrangement is loose enough to be modified by gravity. evaporated: (gas) the attachment becomes insignificant.
What is the procces of of substances changing into a new substance?
The process of substances changing into a new substance is called a chemical reaction. During a chemical reaction, bonds between atoms are broken and reformed to create new substances with different properties. This process involves the rearrangement of atoms to form new molecules.
What happens when a pure substance undergoes a chemical change?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
What is the difference between latent heat of fusion and latent heat of vapourization?
the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization
What happens when substances goes through a phase change?
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
What happens to a substance during between solid and liquid?
It can melt into a liquid, it can be juiced,
What happens to a substance during changes between solid and liquid?
It can melt into a liquid, it can be juiced,
What happens to substance during changes between solid and liquid?
It can melt into a liquid, it can be juiced,
What happens to a substance during chenges between solid and liguid?
Substances changing between soild and liquid undergo Phase Transition and solids absorb energy at constasnt tempertature to phase change solids to liquid. The reverse happens when the liquid turns to solid, energy is given off.
What happens to a substance during changes between solid and I gas?
When a substance changes from a solid to a gas, called sublimation, it quickly becomes less dense.
What happens to temperature as energy is added to a substance that is changing state?
The temperature remains constant during a change of state as the energy is used to break intermolecular bonds rather than increase molecular motion. Once the substance has completely changed state, the temperature will start to rise again as the added energy increases the molecular motion.
How does what happens to the particles in a substance during melting differ from what happens in freezing?
Its the degree of attachment between the molecules of the substance: frozen (solid) the arrangement is fixed. melted (liquid) the arrangement is loose enough to be modified by gravity. evaporated: (gas) the attachment becomes insignificant.
What happens to the original substance during a chemical reaction?
The original substances are transformed during a chemical reaction a new substance (compound) is obtained.
How can a physical property can without the substance changing?
During a physical change the chemical formula is not changed.
