What is a substance that will change from a soild into a liquid?
A substance that will change from a solid to a liquid is called a melting substance. This process is known as melting, where the solid substance absorbs heat energy and transitions into a liquid state.
When does a substance change from a solid to a liquid?
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
Is sublimation physical change?
Yes, sublimation is a physical change in which a substance transitions directly from a solid to a gas without passing through the liquid phase.
What is the change of a phase from a vapor to a liquid called?
The change of phase from a vapor to a liquid is called condensation. This process occurs when a substance loses heat energy and transitions from its gaseous state to its liquid state.
What is a physical property that tells you when a liquid would change into a solid?
The melting point is a physical property that indicates when a liquid will change into a solid. It is the specific temperature at which a substance transitions from a liquid state to a solid state.
How do the molecular energy molecular motion and overall mass of a substance change when matter changes state?
When matter changes state, the molecular energy generally increases as heat is added or decreases as heat is removed. Molecular motion increases as the substance transitions from a solid to a liquid to a gas. The overall mass of the substance remains the same throughout the phase change process, as no particles are added or removed.
What is a substance that will change from a soild into a liquid?
A substance that will change from a solid to a liquid is called a melting substance. This process is known as melting, where the solid substance absorbs heat energy and transitions into a liquid state.
What is the phase change in which substance changes from a gas to a liquid?
The phase change in which a substance changes from a gas to a liquid is called condensation. This occurs when the gas loses energy, typically through cooling, and transitions to a liquid state.
How molecular motion changes as a substance changes from one state to another?
As a substance changes from a solid to a liquid, the molecular motion increases as the intermolecular bonds break and the molecules can move past each other more freely. When a substance transitions from a liquid to a gas, the molecular motion increases further as the molecules have enough energy to overcome intermolecular forces entirely and move independently.
What is the general term used to identify transitions between the solid liquid and gaseous forms of a substance?
phase change

Which type of property is a phase change?
A phase change is a physical property where a substance transitions from one state of matter to another, such as from solid to liquid, liquid to gas, etc.
What happens to density when it changes state?
When a substance changes state, its density can change. For example, when a substance transitions from a solid to a liquid state, its density usually decreases. Conversely, when a substance transitions from a gas to a liquid state, its density typically increases.
Is liquid to gas chemical change?
No, the change from liquid to gas is a physical change, not a chemical change. In this process, the substance's molecular structure remains the same, only its physical state changes from liquid to gas.
Is sublimation physical change?
Yes, sublimation is a physical change in which a substance transitions directly from a solid to a gas without passing through the liquid phase.
What is the change of a phase from a vapor to a liquid called?
The change of phase from a vapor to a liquid is called condensation. This process occurs when a substance loses heat energy and transitions from its gaseous state to its liquid state.
Is the specific gravity of substance the same when the substance is in the solid state?
No. Roughly speaking, "specific gravity" is equivalent to density, i.e., mass divided by volume. If a substance changes its state, its volume will change, but its mass won't change - therefore, the density - the result of the division - will also change.
