How is the mass of a gaseous substance affected after it condenses?
The mass remain unchanged, only the density is variable.
Is a gaseous non-metal?
Gaseous chemical elements are nonmetals.
If an ice cube is placed in a pot that is heated what will happen after it has melted is it a chemical or physical change?
When ice melts and becomes a liquid it is a physical change. When the liquid boils and becomes gaseous it is a physical change. It is a chemical change when the molecular structure has been changed in some way, here it has not.
Is helium a gaseous mixture at room temperature?
Helium is gaseous but it is not a mixture - it is a chemical element.
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.
When ethanol condenses and goes from gaseous state to liquid state is this a physical change or chemical change?
Condensation is a physical change, as the chemical identity of the substance is not altered by condensation.
What state of matter condenses when cooled?
Gaseous matter.
Is water vapor a chemical or physical property or is it a change?
Water vapor is in the gaseous state.
Which reactions shows a physical change?
Burning coal is a chemical reaction, a chemical change; but the solid reactant is transformed in gaseous products (H2O and CO2) - this is a physical change.
Is sublimation of mothballs physical or chemical change?
Physical, since it's just changing the state of matter
Is smashing a pumpkin a physical or chemical change and why?
crushing a sugar cube is a physical change
Can a mixture of liquid and gaseous water be considered a pure substance?
Yes it can, the only difference between liquid and gaseous water is it's physical form, not it's chemical composition.
Which equation represents a physical change?
Burning coal is a chemical reaction, a chemical change; but the solid reactant is transformed in gaseous products (H2O and CO2) - this is a physical change.
How is the mass of a gaseous substance affected after it condenses?
The mass remain unchanged, only the density is variable.
Is bubbles fizzing a physical or chemical change?
Physical. If a substance releases bubbles, it is converting some of its liquid into a gaseous state. The chemical properties do not change, only its present state. A most common physical change is that of watching ice melt in glass of water.
Is water evbaporating from clothes on a washing line a chemical or phsical change?
Physical. The water changes its state of matter from liquid to gaseous. No chemical reaction (i.e. change) going on there.
Is a gaseous non-metal?
Gaseous chemical elements are nonmetals.
