# Is the temperature in which a substance goes from the liquid phase to the gas phase?

## Is the temperature in which a substance goes from the liquid phase to the gas phase?

The boiling point is the temperature at which a substance goes from a liquid to a gas (or from a gas to a liquid). The nature of the phase change depends on the direction of the heat transfer. On the Celsius scale, H2O has a melting point of 0°C and a boiling point of 100°C.

Which term represents the change of a substance from the liquid phase to the gaseous phase?

Vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling. Direct conversion from solid to vapour is called sublimation.

What phase change is involved when liquid turns to gaseous state?

Evaporation
Evaporation is a phase transition from the liquid phase to the gas phase that occurs at temperatures below the boiling point at a given pressure.

### Which of the following refers to the temperature at which a substance turns from liquid to gas?

The process by which a substance moves from the liquid state to the gaseous state is called boiling. The temperature at which a liquid begins to boil is called the boiling point (bp). The bp is dependent on atmospheric pressure, but for water at sea level, it’s 212°F, or 100°C.

What is it called when liquids boil at a specific temperature?

The boiling point is the temperature at which boiling occurs for a specific liquid. For example, for water, the boiling point is 100ºC at a pressure of 1 atm.

What are the 6 types of phase changes?

Sublimation, deposition, condensation, evaporation, freezing, and melting represent phase changes of matter.

#### What are the six phase changes?

Melting, freezing, vaporization, condensation, sublimation, and deposition are six common phase changes.

What eventually happens if energy is continually removed from a liquid?

If energy is continually removed from a liquid, the liquid freezes to become a solid.

What is solid to gas called?

Sublimation is the conversion of a substance from the solid to the gaseous state without its becoming liquid. It occurs more frequently among substances that are close to their freezing point.

## Can two liquids have the same boiling point?

Answer: They cannot be separated by distillation because distillation uses the property of liquids to boil at a certain temperature, if you have to liquid with the same boiling points then the vapour phase will be about 50% of each, thus not separating them.

When does a substance cannot be in a liquid phase?

At pressures below the triple point, a substance cannot exist in the liquid state, regardless of its temperature. The terminus of the liquid-gas curve represents the substance’s critical point, the pressure and temperature above which a liquid phase cannot exist.

How is the temperature of a substance related to its density?

The temperature at which a substance in the liquid phase transforms to the gaseous phase refers to the substance’s _______. Density refers to a physical property that is measured using a ratio of _________ divided by _______ so that two objects of the same size can still have very different density.

### How does temperature affect the phase of water?

At a temperature of 374 °C, the vapor pressure has risen to 218 atm, and any further increase in temperature results in the disappearance of the boundary between liquid and vapor phases. All of the water in the container is now present in a single phase whose physical properties are intermediate between those of the gaseous and liquid states.

How are the phases of a substance determined?

These diagrams indicate the physical states that exist under specific conditions of pressure and temperature, and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). A typical phase diagram for a pure substance is shown in [link].
