Why does lowering pressure cause a liquid to boil?
it becomes easier for the molecules to escape
When the vapor pressure of a liquid equals the air pressure in the room what will the liquid do?
The liquid starts boiling
Energy need to change a material from liquid to gas?
You can add heat and cause liquid to gasify. Or you can decrease the pressure in the system and cause liquid to gasify. Note that you may gasify liquid and leave suspended or dissolved solids behind. More heat or pressure may be required to convert these remnants to liquid and then gas.
Does the constant motion of the particles in a liquid cause the liquid to take the shape of its container?
Yes, pressure in the liquid caused by its molecules constantly being in motion force it to take on the shape of its container (within limits).
Upon what factors does liquid pressure depend?
Atmospheric pressure Density of the liquid Gravitional field strength in the area the liquid is in The distance from the surface of the liquid i.e. depth Pressure in a liquid=Atmospheric pressure +(Depth X Gravity strength X Density) There might be more I don't know about
Why does raising the temperature cause liquid to boil?
Decreasing the pressure -APEX
What are the causes of high suction pressure?
Suction is caused by an are of negative pressure.
How do you change hydrogen gas to a liquid?
Hydrogen is a gas. The only method that can cause this gas to become liquid is pressure.
How does a valve cause a pressure drop in terms of the individual molecules in the liquid?
Soo

What is mean by saturated liquid and vapor?
Any addition of thermal energy to a saturated liquid will cause it to vaporize. Any subtraction of thermal energy from a saturated vapor will cause it to condense.
When the vapor pressure of a liquid is equal to the atmospheric pressure the liquid .?
it begins to boil - Monsy
A decrease in vapor pressure will cause?
It will result in a decrease in the boiling point of a liquid, among other things.
What is the relationship between liquid pressure and the depth of a liquid between liquid pressure and density?
pressure of liquid on bottom=density*gravitational force*depth :)
When the vapor pressure of a liquid equals the air pressure in the room what will the liquid do?
The liquid starts boiling
Why is it not always easy to cause phase changes changing a liquid to a gas f?
In order to change a liquid to a gas, it has to reach its boiling point, which depends on the pressure.
