Temperature where some of a liquid begins to enter the gaseous state?

All substances can have a gaseous state, however, below the triple point (the temperature and pressure at which solid, liquid and gas can co-exist in equilibrium), the equilibrium is between the solid state and the gaseous state. Once you get above the triple point, you can get a gaseous state as long as you are above the melting point of the substance and below the critical point (the temperature at which the gas and liquid states have the same density - above the critical point you get a single "supercritical" phase). Between the triple point pressure and the critical point pressure, the temperature at which some liquids begin to get a gaseous state is know as the "boiling point". For water at sea level, that happens around 100 °C (212 °F) - although anyone who has been camping at high altitudes can attest to the fact that with the lower pressure at high altitudes, the boiling point of water can drop to something barely luke warm.

What is the change when the state of liquid begins to enter the gaseous state?
vaporization There are two types of vaporization - evaporation and boiling.
Liquid changing to gas only at surface is called?
When vaporization takes place only on a liquid's surface, the process is called evaporization.
Is salt and sugar a gas?
Salt and sugar are generally known as crystals but if you increase the temperature enough (1413 degrees for table salt) they will pass the boiling point and enter the gaseous phase where they become gasses (or strictly speaking a plasma)
How does adding fluids to hot rock cause magma to form?
The lithosphere primarily comprises of volcanic rocks and sediments that contain fluids and water. These fluids contact the rocks surrounding as the lithosphere moves into the mantle in the downward direction. The rock's melting temperature decreases when the fluid begins the enter the hot rock. This melts it to form magma.
Does refrigerant enter the compressor as a low temperature low pressure gas?
Yes. The basic components of the refrigeration system are the refrigerant, compressor, condenser and receiver, expansion device and the evaporator. One cycle: Refrigerant travels to Compressor (A) to Condenser (B) to Expansion device (C) to evaporator (D). The refrigerant gas at low pressure and temperature is drawn into the compressor. The gas is compressed to a higher pressure, which causes an increase in the temperature. The refrigerant gas at a high pressure and temperature passes to the condenser (point B), where it is cooled (the refrigerant gives up its latent heat) and then condenses to a liquid. The high pressure, low temperature liquid is collected in the receiver. The high pressure liquid is routed through an expansion valve (point C), where it undergoes an abrupt reduction in pressure. That pressure reduction causes part of the liquid to immediately vaporize or flash. The vapor and remaining liquid are cooled to the saturation temperature (boiling point) of the liquid at the reduced pressure. At this point most of the refrigerant is a liquid. The boiling point of the liquid is low, due to the low pressure. When the liquid refrigerant enters the evaporator (point D), it absorbs heat from the process and boils. The refrigerant gas is now at low pressure and temperature, and enters the suction side of the compressor, completing the cycle.

What state will most likely result if heat is added to a liquid?
It will change into a gas.Adding heat to or removing heat from a system may result in a temperature change and possibly a change of state. A liquid substance needs heat added to it in order to enter a gaseous state. If enough heat is added to a liquid substance it will change into a gas.
When does water enter a gaseous state?
When it evaporates.
Why is the bioling point of hexane greater than that of pentane?
Higher molecular weight, so needs more kinetic energy (higher temperature) to enter the gaseous phase.
Why do you use clinical thermometer to measure the temperature of boiling water?
There's actually no need to measure the temperature boiling water. If water is boiling, it will always be 100°. This is because boiling is a cooling process. As you apply heat, water molecules who want to boil, breaking free and enter the gaseous phase. When this happens, they take some of the energy that you imported into the liquid with them. Thus once the liquid reaches the boiling temperature water will continue to evaporate until there is no more water left. During this time, it will remain 100°.
Liquid changing to gas only at surface is called?
When vaporization takes place only on a liquid's surface, the process is called evaporization.
What is vaporization throughout a liquid?
You may be referring to boiling. First a little background.Vaporization is a phase change from the liquid state to the gaseous (or vapor) state. When a liquid vaporizes or evaporates, the more energetic molecules in the liquid leave the surface and enter the vapor phase in the air above the liquid. Because its the more energetic molecules that leave the liquid, and the kinetic energy of a molecules is related to the temperature, vaporization is a cooling process. Another term for this is endothermic, meaning it takes in heat.When a liquid is below its boiling point, not all molecules uniformly have enough energy to enter the vapor state. Some molecules have more energy and go into the vapor, others don't and stay behind in the liquid state. As an average, the liquid exhibits a vapor pressure less than that of the atmosphere. The vapor pressure of a liquid is a function of its temperature.When a liquid reaches its boiling temperature, however, that means the liquid's vapor pressure (as a whole) equals that of the atmosphere. So instead of evaporation just from the surface, now you see bubble of water vapor forming throughout the liquid and rising to the surface.
What is the kinetic energy level necessary for a molecule to enter the gaseous phase is known as?
Emin
How does the addition to fluid relate to the formation of magma?
When the fluids enter the already hot mantle rock, the melting temperature of the hot rock decreases. As a result, the rock begins to melt.
Is salt and sugar a gas?

What are the elements that are liquid?
There are only a few elements that officially classed as liquids. To be classed as a liquid, an element must be in liquid state at room temperature. There are only two known elements that are liquids at room temperature. They are:Mercury (Hg) - Atomic Number 80 - Transition MetalBromine (Br) - Atomic Number 35 - Group 17(7) Halogen
