Is heat added or taken away in solid to gas?

When a solid transitions to a gas, heat is added to the solid. This process, called sublimation, involves the solid absorbing energy, which allows its particles to overcome intermolecular forces and disperse into the gas phase. Therefore, heat is required for this transformation.


Heat being added or taken away from a substance may cause?

more or less heat


What must be added or taken away for a change in the state of matter to occur?

I believe "heat"To change from one state of matter to another state of matter heat is added or taken away.I think that makes sense!


Is heat taken away or added in evaporation?

Heat is taken away during evaporation. As the liquid absorbs heat from its surroundings and gains energy, some of the molecules at the surface of the liquid gain enough energy to overcome the intermolecular forces holding them together, and they escape into the gas phase. This process removes heat from the remaining liquid, causing it to cool down.


What is solid to a gas and is heat added or removed?

Of course heat is added because you are turning solid which is like ice to gas which is water vapour !!


Is heat added or removed during sublimation?

During sublimation, heat is added to the substance. This process involves a solid transforming directly into a gas without passing through the liquid phase, which requires energy in the form of heat to overcome the intermolecular forces holding the solid together. As a result, the temperature of the solid decreases while it absorbs heat, enabling the transition to the gaseous state.


What has to be taken away to turn ice into water?

What are affected by an increase in intermolecular forces?

What happens to water when heat is taken away?

It becomes cold.


When heat is taken away what happens to the speed of the molecule?

It slows.


Do you add heat or remove heat to turn a solid into a gas?

To turn a solid into a gas, you need to add heat. This process is known as sublimation, where the added heat provides the energy necessary for the molecules in the solid to overcome intermolecular forces and transition directly into the gaseous state.


When heat is taken away from something what happens to the mercury in the thermometer?

It contracts.
