What else can I help you with?
Why can you smell the scent of perfume across the room?
The molecules of perfume are in a gaseous state and mixing with the molecules of air in the room. All of them undergo random motion at all times as a result of the internal ("heat") energy that they have absorbed.
Can a gas diffuse to gas?
It can. If you put an open bottle of perfume on the table, you'll be able to smell it at a distance after some time, because the perfume vapors--a gas--have diffused into the air.
Is the smell of alcohol a physical change?
The smell of alcohol is not a physical change; rather, it is the result of the volatile compounds in alcohol evaporating into the air. When alcohol evaporates, it changes from a liquid to a gas, which can be detected by our sense of smell. This process is a physical change, as it involves a change in state without altering the chemical composition of the alcohol itself.
How fusion change state of matter?
Because melting is a change of state: from solid to liquid.
How do solids and liquids change state?
they change their state by absorbing heat known as latent heat. There is no temperature change in a substance she they change their state because the heat is used to break the intermolecular bonds between the molecule.
What is the change of state when a person opens perfume and you can smell it on the other side of the room?
because you can
Why can you smell the scent of perfume across the room?

Which state of matter has properties that are responsible for your smelling the perfume of someone across the room?
The gaseous state of matter is responsible for you smelling the perfume of someone across the room. The perfume molecules evaporate into the air as gas particles and travel through the air to reach your nose. This is how you are able to smell the perfume from a distance.
Which state must be a material be in to be smelt?
Gas, for example perfume may be sprayed on fabric to make it smell nicer.
How a perfume bottle change its state?
A perfume bottle changes its state from liquid to gas when the liquid perfume inside is sprayed out and comes into contact with the air. The liquid perfume evaporates quickly due to its volatile components, leaving behind a lingering scent in the air.
Is perfume evaporating on your skin a chemical change or physical change?
The evaporation of perfume is a physical change. The chemical constitution of the perfume has not changed, it is still exactly the same chemical, but it has changed from a liquid phase to a gas phase.
Can a gas diffuse to gas?
It can. If you put an open bottle of perfume on the table, you'll be able to smell it at a distance after some time, because the perfume vapors--a gas--have diffused into the air.
Why is ice cream melting a physical change?
Melting is a change of state. Technically you could chill it again and change it back to icecream. You'd just have to have it churning to keep it mixed correctly. Now, if it spoils, then that is a chemical change! You can tell by a change in color, smell and inability to change it back to its original state.
Why is a change in state a physical change rather than chemical change?
Because it can change from one state to another.
Is diffusion a chemical reaction or a change of state?
Diffusion is a change of state. A good example of diffusion is when you can smell something cooking that is in another room. Moisture in the food evaaporates and the gas formed is diffused and you can smell it. I'm not sure that I'm right but i learnt about diffusion in science recently ;-)
How fusion change state of matter?
Because melting is a change of state: from solid to liquid.
The change in which ice absorbs energy and melts is?
An endothermic change; or a change of state. Endothermic because it absorbs energy. Change of state because ti changes from a solid to a liquid.
