What pressure for a chemical or solution is considered an explosive hazard?
when the vapor pressure is greater than 5 mm
Water to form a gas physical or chemical property?
water forming water vapor is physical change
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
Is liquid water a water vapor?
No: Vapor is defined as the gas phase of a substance that is mostly solid or liquid at equilibrium at standard temperature and pressure. Therefore, a liquid itself is never a vapor, but the liquid is in equilibrium with a vapor phase that contains the same chemical substance.
What happens to vapor pressure if sugar is added to a solution?
When you add a teaspoon of honey to water with vapor pressure, it will reduce the vapor pressure. The sugar in the honey leads to the pressure going down.
Is increase of vapor pressure a colligative property?
The lowering of the vapor pressure is a colligative property.
Is evaporation a chemical property?
It is not a property it is the process of turning a liquid into a gas. The enthalpy change of evaporation would be a chemical property.
A banana browning in the air is an example of state physical property vapor or chemical property?
chemical
Is water vapor a chemical or physical property or is it a change?
Water vapor is in the gaseous state.
What chemical does an airplane exert into the air?
Carbon dioxide, water vapor, and traces of other chemicals.
What type of chemical pollutant are responsible for the ozone depletion and where do these chemicals come from?
water vapor, oxidized
What pressure for a chemical or solution is considered an explosive hazard?
when the vapor pressure is greater than 5 mm
What is the vapor pressure considered a chemical or solution considered an explosive hazard?
ho2
What physical property makes acetone so dangerous?
It has a high vapor pressure (it is volatile).
Which property is not important when selecting a material to use as a light bulb?
High vapor pressure
How does a solution containing a chemical with a high vapor pressure be low in volatility?
Well vapor pressure also depends on the mole fraction of a substance. Vapor pressure= Mole fraction* Total pressure of the solution. If the Mole fraction of a volatile substance in the solution is decreased its vapor pressure increases. Thus the volatility of the substance barely plays the role. Of course, if the solution has no volatile substance there cannot be any vapor pressure in the container.
Which property is not important when selecting a material to use as a light bulb filament?
High vapor pressure
