What else can I help you with?
What do you call when lava beneath the crust?
Magma; they are both the same substance, but lava has been exposed to the surface.
True or False The less surface area the faster a substance will change from a solid to a liquid?
When a substance goes from a solid to a liquid, it is melting. Generally, it is easier to heat an object that has more surface area because it has more area being exposed to heat.
What is effloroscent?
Efflorescent refers to a substance that loses moisture and forms a powdery deposit on its surface. This phenomenon often occurs in salts and minerals when they are exposed to air.
Will a substance dissolve faster if it is ground into powder first?
The dissolution rate of a substance is affected by the surface area that can react with the liquid it is dissolving in. Powdering it increases the surface area so it increases the dissolving rate.
If ambient room temperature is a constant 22 degrees celsius how much of a liter of water would evaporate in 12 hours and is the size of the exposed surface area of 1 liter relevant to evaporation?
-- the area of the exposed surface -- the airflow over the exposed surface -- the temperature of the liter of water -- the air pressure at the exposed surface -- the relative humidity of the air in the room -- the transparency of the liter container are all relevant to the rate of evaporation.

What substance changes color when exposed to an acid or base?
An indicator is a substance that changes color when exposed to an acid or base.

What does SA in surface finish SA 2.5 stand for?
The SA mentioned here refers to Surface Area, or how much surface the substance will cover
How does the area of exposed surface affect evaporation?
The larger the exposed surface area, the faster the rate of evaporation, as there is more surface area for the liquid molecules to escape into the air. This is because more molecules are exposed to the air, increasing the likelihood of evaporation occurring. Conversely, a smaller exposed surface area will result in slower evaporation.
An example of evaporation is faster when the exposed surface of water is large?
When the exposed surface of water is larger the evaporation is faster.
yes if you use a substance then the surface will be cleaner?
If you clean with a cleaning substance and use appropriate cloths and rags your much more likely to have a cleaner surface. It also depends on the type of surface that is being cleaned. For example your more likely to be successful with a cleaning substance on linoleum than water.
Why is surface area important to burning?
Burning is a chemical process - oxidation - that usually takes place where oxygen from the air reacts with the substance that is burning. The surface area determines how much oxygen is in contact with the substance.
What is size of solute?
It is the amount of surface of a solute that is exposed to the solvent. The smaller the pieces of the solute are, the larger the surface area that is exposed to the solvent.
