When a substance undergoes a phase change it still has a definite A mass B shape C volume D temperature?
mass - the mass does not change
Does iron undergo change when it is moist?
when a substance undergoes changes in its phase,its physical properties change.physical properties are properties you can observe without changing the material into another substances.
What is phase change in light of wavelength 600-NM incident in a material with index of refraction n equals 1.38 when it reflects from a material with index of refraction n equals 1.40?
When a light ray is incident on a boundary of greater density than the current medium, the reflected ray undergoes a 180 degree phase change
Evaporton is a phase change form?
Evaporation is not a phase change form i is a process by which phase change.
What is volatile solvent?
A solid that can easily tranform into a gas.
What happens to gas when it contracts?
It undergoes phase change and becomes a liquid.
What happens to a gas when it reaches the condensing point?
It undergoes a phase change, and turns to liquid.
What happens to a gas when it reaches it condensation point?
It undergoes a phase change, and turns to liquid.
Why butane is easy to undergo a change in phase?
Because its Boiling point is closer to normal room temperature.
What is a gas to a liquid?
Liquid to a solid is: freezingLiquid to a gas is: condensationSolid to a liquid : is meltingGas to a liquid is: evaporation
When a substance undergoes a phase change it still has a definite A mass B shape C volume D temperature?
mass - the mass does not change
Describe refrigerant properties of density?
A refrigerant is a compound use in a heat cycle that undergoes a phase change from a gas to a liquid and black
What doe condensing mean?
Condensing is when a substance undergoes a phase transition from the gas phase to the liquid phase.
Which statement describes the phase change that occurs when dry ice is placed in an open container at room temperature?
Dry ice undergoes sublimation, an exothermic change, at room temperature.
Can a physical change occur without the matter changing chemically?
Absolutely. When water, for example, undergoes a phase change from solid ice to liquid water, the chemical form remains unchanged.
Why is a phase change only a physical change?
See "Related Questions". Phase changes are reversible by adding or subtracting heat. In many cases chemical changes are not easily reversed.
What do matter undergoes?
The most important are changes of phase: melting, boiling, freezing.
