What is the amount of energy can change a solid phase to a liquid phase?
The amount of energy required to change a solid phase to a liquid phase is known as the heat of fusion. It is the amount of heat energy needed to overcome the intermolecular forces holding the solid molecules together and allow them to transition into a liquid state. This energy varies depending on the substance and is usually expressed in joules per gram (J/g).
When you add 100 joules of heat to a glass of water the temperature goes up When you add 100 joules of heat to water with ice cubes in it the temperature stays the same Why?
When 100 joules of heat is added to a glass of water, the energy increases the kinetic energy of the water molecules, raising the temperature. However, when adding the same amount of heat to water containing ice cubes, the energy goes into melting the ice rather than increasing the temperature of the water. This process, called latent heat, absorbs energy without a change in temperature until all the ice has melted. Thus, the temperature remains constant while the phase change occurs.
When liquid water evaporates to water vapor it?
This change of phase is called evaporation.
When you boil water on stove until it turns to steam you are witnessing a?
physical change called vaporization where the liquid water changes to steam (water vapor) due to the heat energy supplied. This process involves a phase change from liquid to gas without altering the chemical composition of the water molecules.
Water changing to steam is an example of what kind of change?
Water changing to steam is an example of a physical change, specifically a phase change from liquid to gas. This change is reversible as the steam can condense back into water under certain conditions.

The amount of energy required to change a solid phase to a liquid phase is known as the heat of fusion. It is the amount of heat energy needed to overcome the intermolecular forces holding the solid molecules together and allow them to transition into a liquid state. This energy varies depending on the substance and is usually expressed in joules per gram (J/g).
What is a phase change example of?
When ice melts and becomes water, that is a phase change. Same when water boils and becomes steam (a gas) that is also a phase change.
How many joules are needed to change the temperature of 1 gram of water by 1C?
It takes 4.184 joules of energy to change the temperature of 1 gram of water by 1 degree Celsius.
What phase change causes water to evaporate?
This phase change is called evaporation.
What phase does water change to when boiled?
Water changes from a liquid phase to a gaseous phase when it is boiled.
If water is evaporated what is the change of state?
The change of state when water is evaporated is from liquid to gas. Evaporation is a phase transition from the liquid phase to the gas phase.
What happens when water releases 334 joules of latent heat?
When water releases 334 joules of latent heat, it transitions from a gas to a liquid state or from a liquid to a solid state without a change in temperature. This energy is used to break the intermolecular bonds between water molecules during the phase change process.
Which of the following is an example of a phase change from liquid to solid?
Frost is a phase change of a gas to a solid (deposition). Water vapor turns directly to ice.
What is the temperature of a substance does not change before the?
The Phase Change is complete, e.g water melting from ice phase to liquid phase or water evaporating from liquid to gas. Save
If heat is released from water what phase change occurs?
If heat is released from water, the phase change that occurs is from gas (water vapor) to liquid (water). This is known as condensation.
Is water condensing a physical or chemical change?
Water condensing is a physical change. It is a change in state from the gaseous phase (water vapor) to the liquid phase (liquid water) without any change in the chemical composition of water molecules.
What happen when water vapor from the hot water cools?
A change of phase; from gas phase (water vapors) to liquid phase; the phenomenon is called condensation.
