In the case of road tar, it is solidification (Liquid -> Solid). In the case of, say, gasoline or kerosine, it is evaporation (Liquid -> Gas).
Because petrol is volatile, some of it evaporates into the air and that's what you smell.You can smell petrol at a petrol station because sometimes people spill it as they put it into their cars.
Evaporation is when a liquid turns into a gas, like water drying up on the ground and disappearing into the air. It happens when the sun heats up the liquid and causes it to change into tiny, invisible particles that float away.
Petrol is a homogeneous mixture. It is made up of different hydrocarbon compounds that are evenly distributed throughout the mixture, giving it a uniform composition.
Evaporation of a pudle is a physical change,
No, sunlight speeding up the evaporation of water is not a chemical change. It is a physical process where the water molecules transition from liquid to vapor state without any change in their chemical composition.
Why are wells drying up now days
The drying up of the sahara force farmers to move away from what had once been lush green areas to other areas that did not suffer from such ecologicak change
demand of petrol are going up year by year and petrol is nonrenewable source of energy
It is a physical change, because it is still H20 when it evaporates and turns into vapor.
It is best not to speed up the drying time for plaster of Paris. If you speed up the drying time it will not set up as it should. If you still want to speed up the time, you could use a blow dryer.
in some places petrol prices have gone up but in some places they have kept the same
