What kind of changes are melting and boiling?
Melting is a phase change where solid becomes a liquid. The latent heat of fusion must be supplied to produce phase change from solid to liquid. About 144 Btu must be supplied to change 1.000 pound of ice at 32 degrees F to 1.000 pound of liquid water at 32 degrees F. Boiling is a phase change where a liquid becomes a vapor. The latent heat of vaporization must be supplied to change a boiling liquid to a vapor. For water boiling at 14.7 psia ,970.3 Btu of heat must be supplied to change 1.000 pound of boiling liquid water to vapor.
Bubbles begin to form in a sample of liquid but the temperature did not change What must happened to cause the change?
There may have been some gas in the liquid, or maybe there was a decrease in pressure.
Can oxygen exist as a liquid?
Yes, but under atmospheric pressure it must be cooled to 90 Kelvin, about -183 Celsius.
Why must welder immediately change clothing if the clothing becomes saturated with oxygen?
Pure oxygen is extremely flammable (the air we breathe is only about 21% oxygen).
How do intermolecular forces affect the boiling of a liquid?
The stronger the forces, the more heat that must be added to boil the liquid
What must be done to oxygen and hydrogen to change them to liquid?
If you mean the individual gases you will need to apply pressure and or reduce the temperature to liquefy the gases. If you mean by forming a compound react them together. The end product is water which is liquid at room temperature and pressure.
Is oxygen liquid?
Can you breathe liquid? No, so oxygen must be a gas because that's what everyone breathes.

How do you change a gas into a liquid give an example?
To change from a gas into a liquid you must cool the substance. For example: water vapour to water.

Is there loss of heat during change of state of matter from liquid to gas?
Yes there must be achange;but heat is required to change liquid state into gaseous state.

When an aircraft is being serviced with liquid oxygen (LOX) a vehicle operator must maintain from the aircraft?
25 feet
How do you change liquid to gas?
To change the phase of a system from liquid to gas, the total system energy must be increased (heat added) to the point where every atom or molecule has sufficient energy to escape the liquid system.
What must be done to change the way we elect our president?
make them eat cake
