What is the energy needed for a substance to change from liquid state to a gaseous state?
thermol
Which substance in the gaseous state should be calleda vapour?
A substance in the gaseous state that is typically a liquid or solid at room temperature can be referred to as a vapor. Examples include water vapor or steam, which is the gaseous state of water.
Which is the only planet where the same substance can exist in gaseous and liquid and solid form?
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
Can you regard the gaseous state of alcohol as vapours?
Yes, the gaseous state of alcohol can be regarded as vapors. Vapors are defined as the gaseous phase of a substance that is typically found in a liquid or solid state at room temperature and pressure. When alcohol evaporates, it transitions from its liquid form to a gaseous state, forming vapor that can be observed in the air. This vaporization occurs due to the heat energy that enables alcohol molecules to overcome intermolecular forces and enter the gaseous phase.
Is there a difference between the gaseous and liquid state of the same substance?
yes
How is the temperature of a gaseous substance related to the average kinetic energy of the particles in the substance?
if the temperature of the substance is raised then the kinetic energy of the gaseous particles will also increase....
What is the energy needed for a substance to change from a liquid state to a gaseous state?
thermol
Can a liquid substance diffuse in another liquid substance a gaseous in liquid a gaseous in gaseous?
Yes, all of them.
Does a substance gain o lose thermal energy when it evaporates?
A substance gains thermal energy when it evaporates, as energy is required to break the intermolecular forces holding the molecules together and allow them to escape into the gaseous phase.
How much energy released by dihydrogen in gaseous state?
The energy released by dihydrogen in its gaseous state would depend on the reaction it undergoes. When dihydrogen reacts with another substance, such as oxygen, the energy released is a result of the bond formation in the products. This energy can be calculated using methods like calorimetry.
What is the energy needed for a substance to change from liquid state to a gaseous state?
thermol
Which change in state requires that energy be added to the substance?
Melting solid into liquid requires energy to be added to the substance.
Why does water get cooled in evaporation?
It takes energy to boost a liquid or solid into a gaseous state, so an evaporating substance must aborsb thermal energy.
Does it mean that substance at a gaseous state does not have attraction forces?
NO it does not mean that substance at a gaseous state does not have attraction forces . It simply means that they have very very very weak forces of attraction . Therefore they have very high kinetic energy as compared to other physical states.
What is the gaseous form of a substance which exist as a liquid at room temperature known as?
The gaseous form of a substance that exists as a liquid at room temperature is known as vapor.
The process in which a substance changes from a gaseous state to a liquid state is?
Condensation is the process in which a substance changes from a gaseous state to a liquid state. This occurs when the gas loses energy (usually in the form of heat) and becomes more tightly packed together, forming liquid droplets.
Which substance in the gaseous state should be calleda vapour?
A substance in the gaseous state that is typically a liquid or solid at room temperature can be referred to as a vapor. Examples include water vapor or steam, which is the gaseous state of water.
