→ Vaporization is a process which occurs when a element or a chemical is converted from a liquid or solid to a gas.
What is vaporization in chemistry class 8?
The process of change of liquid to vapours on heating is called vaporization.
What is latent heat of vaporization Class 9 short answer?
Latent heat of vaporization is the heat consumed or discharged when matter disintegrates, changing stage from fluid to gas stage at a consistent temperature.
Is condensation a vaporization or fusion?
Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization.
What happens to particles before during and after vaporization?
If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.
How do liquid particles move?
In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.
What process occurs when the heat of vaporization of water is reached?
Water is converted from its liquid form to its gaseous form (steam) when the heat of vaporization is reached.
What is vaporization that takes place below and at the surface of a liquid?
Vaporization that takes place below the surface of a liquid is called boiling. When a liq- uid boils, bubbles form within the liquid and rise to the surface, as shown in Figure 12. The temperature at which a liquid boils is called the boiling point.
What does heat of vaporization depend on?
point and a high latent heat of vaporization compared with other liquids; that is, it takes considerable heat to turn liquid water into steam, which is available when the steam is condensed. The boiling point and the heat of vaporization both depend on ambient pressure.
What is the difference between gas and Vapour?
Vapour is a substance that is a combination of gaseous and liquid phase in ordinary conditions. Gas is a substance that has a single thermodynamic state in ordinary conditions.
Which will evaporate faster water or petrol give reason?
Petrol, or gasoline, evaporates faster than most liquids because of its weak intermolecular attractions. … In comparison, water evaporates more slowly than petrol. That’s because water molecules have hydrogen bonding which is a strong intermolecular attraction.
What is the difference between vaporization and boiling quizlet?
Distinguish between evaporation and boiling. Evaporation happens at a liquid surface, whereas boiling occurs in the bulk of the liquid. … Boiling is a cooling process, so energy is removed as quickly as it is added.
