When a substance changes from one state to another do the chemical properties change?
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
Which is the only planet where the same substance can exist in gaseous and liquid and solid form?
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
When a substance changes from a liquid to a gas energy is . When a substance changes from a gas to a liquid energy is .?
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
Is there a difference between the gaseous and liquid state of the same substance?
yes
What is the energy needed for a substance to change from a liquid state to a gaseous state?
thermol
Which change in state requires that energy be added to the substance?
A phase change from solid to liquid requires energy .likewise a liquid will vaporise into the gaseous state after appropriate increase in energy.
Can a liquid substance diffuse in another liquid substance a gaseous in liquid a gaseous in gaseous?
Yes, all of them.
When a substance changes from one state to another do the chemical properties change?
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
What Heat of is the energy needed for a substance to change from liquid state to a gaseous state?
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
What is the process by which molecules at the surface of a liquid absorb enough energy to change to a gaseous state?
Evaporation is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
How does kinetic energy change with each state of matter?
When any substance goes from solid to liquid to gas, the kinetic energy of the molecules increases.Molecules in the gaseous state have the most kinetic energy.Molecules in the solid state have the least kinetic energy.
Solid ice will change to liquid water and then to gaseous steam when you add what?
Energy because energy can be used as heat.
What is a change of substance from one state of matter to another called?
Phase change. Liquid phase to gaseous phase (evaporation) Liquid phase to solid phase (solidification, freezing) Solid phase to gaseous phase (sublimation9 Etc...
What is the general term used to identify transitions between the solid liquid and gaseous forms of a substance?
phase change
Why does water get cooled in evaporation?
It takes energy to boost a liquid or solid into a gaseous state, so an evaporating substance must aborsb thermal energy.
