What is the energy needed for a substance to change from liquid state to a gaseous state?
thermol
When a substance changes from liquid to solid what is the energy?
The energy released is called the latent heat of fusion. This energy is needed to overcome the attractive forces between the particles of the substance to allow them to transition from a liquid to a solid state.
Draw and discuss the relationship of heat of fusion and heat of vaporization?
The heat of fusion is the energy required to change a substance from solid to liquid at its melting point, while the heat of vaporization is the energy required to change a substance from liquid to gas at its boiling point. Both values are specific to each substance and represent the amount of energy needed to break intermolecular forces during phase changes, with vaporization requiring more energy than fusion due to the additional change in state.
What energy needed to change 1 kg of liquid into gas at boiling point?
Thermal Energy
How is the H fusion used to calculate the energy needed to melt a mass of solid?
The heat fusion (H fusion) is the amount of energy required to change a substance from solid to liquid at its melting point. To calculate the energy needed to melt a mass of solid, you multiply the mass of the substance by its heat of fusion. The formula used is ( Q = m \cdot H_f ), where ( Q ) is the energy required, ( m ) is the mass, and ( H_f ) is the heat of fusion. This calculation provides the total energy needed to completely melt the solid into a liquid at its melting temperature.

What is the engery required to go from liquid to gas called?
The energy needed to go from a liquid to a gas is referred to as heat of vaporization.
Is energy flow involved in a change in state?
Yes, energy flow is involved in a change in state. When a substance changes state, such as from solid to liquid, energy is either absorbed or released. This energy is needed to break the bonds between molecules in the solid state or to form new bonds in the liquid state.
What energy is needed to change a material from a liquid to a solid?
energy
What is the difference between the heat of fusion and the heat of vaporization in terms of their effects on phase changes?
The heat of fusion is the energy required to change a substance from a solid to a liquid, while the heat of vaporization is the energy needed to change a substance from a liquid to a gas. Both are types of phase changes that require specific amounts of energy to occur.
What is the energy required to go from liquid to gas called?
The latent heat of vaporization
What is the heat energy needed to change a liquid to gas while the temperature stays the same?
The heat energy needed to change a liquid to gas while the temperature stays the same is called the heat of vaporization. This energy is used to overcome the intermolecular forces holding the liquid molecules together and convert them into a gas. It is a phase change process that occurs at the boiling point of the substance.
What Heat of is the energy needed for a substance to change from liquid state to a gaseous state?
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
What is the relationship between the heat of vaporization and boiling point of a substance?
The heat of vaporization is the amount of energy needed to change a substance from a liquid to a gas at its boiling point. The higher the heat of vaporization, the higher the boiling point of the substance.
