What must be present in order for asubstance to changev from one state of matter to another?
In order for a substance to change, a certain temperature or pressure must be reached.
What is the boiling point of matter?
When a substance is heated to its boiling point, the liquid begins to turn into a vapor. Thus, both phases of matter (liquid and vapor) will be present. Boiling point is the temperature at which atmospheric pressure equals the vapor pressure of the liquid. For this reason, the liquid is able to be released into the atmosphere as a gas.
Which substance is present in fluorescent tube?
Mercury and Phosphorous.
What substance should be present in dialysis solution?
urine
Substance present in smaller amount in a mixture?
The substance in a solution that is present in the smaller amount is called the solute. The substance that has a higher amount is called the solvent.
What substance present in your body balances the atmospheric pressure actin on us?
what substance present in your body balances the atmospheric pressure action on us
What is difference between extensive and intensive properties?
* Intensive - Properties that do not depend on the amount of the matter present. ** Color ** Odor ** Luster - How shiny a substance is. ** Malleability - The ability of a substance to be beaten into thin sheets. ** Ductility - The ability of a substance to be drawn into thin wires. ** Conductivity - The ability of a substance to allow the flow of energy or electricity. ** Hardness - How easily a substance can be scratched. ** Melting/Freezing Point - The temperature at which the solid and liquid phases of a substance are in equilibrium at atmospheric pressure. ** Boiling Point- The temperature at which the vapor pressure of a liquid is equal to the pressure on the liquid (generally atmospheric pressure). ** Density - The mass of a substance divided by its volume * Extensive - Properties that do depend on the amount of matter present. ** Mass - A measurement of the amount of matter in a object (grams). ** Weight - A measurement of the gravitational force of attraction of the earth acting on an object. ** Volume - A measurement of the amount of space a substance occupies. ** Length
What phase is present at room temperature and normal atmospheric pressure?
solid. *Sources: MasteringChemistry & college student
Explain the functional importance of the partial vacuum that exists in the intrapleural space?
If not present (and the intra-alveolar pressure equaled atmospheric pressure) the lungs would collapse.
What are the 5 external factors that must be present to sustain life?
oxygen,water,normal body temperature,appropriate atmospheric pressure,nutrients
What is the atmospheric pressure as you climb further up?
The atmospheric pressure DECREASES. That's why they supply emergency oxygen masks in planes and why mountain climbers also carry oxygen tanks just in case because it becomes tougher to breath as you ascend. The amount of oxygen present diminishes.
The temperature at which the vapor pressure of a liquid has an external pressure of 1 ATM is the?
The vapor pressure of a liquid is equal to 1 atmosphere at 100 degrees Celsius, or 212 degrees Fahrenheit. This is because for a liquid to boil, its vapor pressure must rise to reach standard atmospheric pressure, which is about 1 atmosphere. When enough heat is present to do this, the substance will boil.
What causes atmospheric pressure?
Amospheric pressure is caused by the weight of air molecules above it. As elevation increases, fewer air molecules are present. Therefore, atmospheric pressure always decreases with increasing height.
On a bright sunny day the average atmospheric pressure is what?
When it is bright and sunny outside, it is typically an indication that high air pressure is present. When pressure begins to drop, a disturbance can be near and weather conditions will begin to deteriorate.
What is the first atmospheric condition leads to the monsoon?
This would be moisture buildup present in the air. The high pressure from this would develop over the area, getting conditions ready for the monsoon.
What are the atmospheric gases present on the Moon's surface?
i have no clue
Why atmospheric components present in small quantities?
evaporation
