interconversion between solid to liquid to gas is physical change
Physical because a substance can be a solid, liquid, or gas and still have the properties of that element/compound
The state of matter (solid, liquid, gas, plasma) is a physical not a chemical property.
A change in density may accompany a Physical change. When liquid water becomes solid water, the solid water FLOATS; (is less dense) on top of its liquid form.Density itself is a physical property, not a change.
Solid, liquid, gas and plasma (fundamental states of matter) are physical properties.
Solid is a physical property.
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
Iodine is an element and its special property is sublimation, this is a physical change from solid iodine to gasous iodine with no liquid phase(or state) in between.
The density of solid gold is physical property
This is chemical property
chemical
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
It is both:It is a physical property because the solid salt becomes part of the liquid state of the water.It is a chemical property because the act of dissolving in water changes the salt (NaCl) into separate ions.
