What else can I help you with?
Is the liquid propane in a barbeque ignites upon contact with a spark a chemical or physical change?
Propane burning is a chemical change. The propane reacts with oxygen. New compounds are the result of the process.Let me add a little more information to this. Propane stored in the tank is in liquid form under pressure (actually an equilibrium of propane gas in the top of the tank, and liquid propane in the bottom). When you open the valve, the gas escapes into the hose and goes to the burners.As the gas escapes, some of the liquid propane evaporates into gas form.The change from liquid to gas is a physical change.
Are there any gases that can turn into a liquid?
Many gasses will turn to liquid when compressed, as in Propane, when compressed becomes liquid propane gas LPG
Why do propane tanks stay cool when the burner is on?
Because the propane in the tank is mostly liquid and as the propane gas at the top of the tank is removed to be burned the liquid propane must evaporate to replace it. Evaporating a liquid requires heat, which the liquid takes from things around it. The tank is in closest contact with the liquid propane, so it cools fastest.
How much liquid gas in a 100 ln propane tank?
23.6 gallons. That's the volume of 100 lbs of propane, however, they only fill to about 80% (to allow room for expansion with temperature; otherwise you'd blow out liquid propane!).
Which of these liquid will evaporate the quickest water propanol or hexanol?
Water is evaporated first.

What is a liquid that starts with a?
alcohol (at least if you are talking about ethanol, methanol, propanol, or iso-propanol)
Does propane dissolve in hexane?
Propanol and water are miscible in all proportions.

Is propane a liquid or a solid or gas?
gas and liquid

Does glycerol have a higher viscosity than propanol?
Yes, glycerol has a higher viscosity than propanol. Glycerol is a more viscous liquid due to its larger and more polar molecule structure compared to propanol.

What is patio gas?
LP, Liquid propane, Propane. All the same thing.
Which of these liquid will evaporate the quickest water propanol or hexanol?
Water is evaporated first.
What is liquid petrolium gas?
Propane
At what temperature is the liquid and solid 1-propanol in equilibrium?
The equilibrium temperature at which liquid and solid 1-propanol coexist is its melting point, which is -126 degrees Celsius. At this temperature, the solid and liquid phases are in equilibrium, with the rate of melting equal to the rate of freezing.
