The process in which a substance changes from a gaseous state to a liquid state is?
condensation =)
What happens when a substance undergoes a physical change?
Physical changes refer to changes of state: solid to liquid or liquid to gas (or vice versa). The chemical structure of the substance does not change, only the amount of energy it contains.
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.
Are changes in the state of matter are physical chemical or neither?
changes in states of matter are physical changes, as they do not affect the chemical properties of the substance
What happens to the pH of an acid when an acid is added?
when acid is added to a substance in the pH, the substance rises in a pressurized state
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
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.
What happens to a substance as its thermal energy increases?
if temperature changes that means there is thermal energy in a substance
What happens when a substance changes state from a solid or liquid?
This change in the state of matter (liquid to solid) is called freezing.This change in the state of matter (solid to liquid) is called melting.They are physical change, the chemical nature of the molecules is not changed.
Which term is defined as the process by which a substance changes state from solid to liquid-?
melting
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
When a substance changes from one state of matter to another it is call?
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.
When a substance changes from one substance to another?
The "blank form" could be "state".
The process in which a substance changes from a gaseous state to a liquid state is?
condensation =)
What is the temperature at which a substance changes from a solid state to a liquid state?
The freezing point is when a liquid changes into a solid.
What happens to water as it changes state?
The density changes.
