What else can I help you with?
The energy involved in a phase change is called the?
Heat associated with phase change is called Latent Heat
How can you add heat to a substance without raising its temperature?
One way to add heat to a substance without raising its temperature is by changing its state of matter. This process, known as phase change, involves adding heat energy to a substance to change it from a solid to a liquid or from a liquid to a gas. During this phase change, the temperature of the substance remains constant until the phase change is complete.
What is the opposite of latent heat?
The opposite of latent heat is sensible heat. Sensible heat is the heat that causes a change in temperature of a substance without a change in phase.
What is the difference between specific heat and latent heat, and how do they affect the heat transfer process?
Specific heat refers to the amount of heat required to raise the temperature of a substance by one degree Celsius, while latent heat is the heat absorbed or released during a phase change without a change in temperature. Specific heat affects the temperature change of a substance, while latent heat affects the phase change process. Both specific heat and latent heat play a role in heat transfer processes by determining how much heat is needed to change the temperature or phase of a substance.
What is happening to a substance undergoing heat of fusion?
During the heat of fusion, a substance is transitioning from a solid phase to a liquid phase. The heat energy is being absorbed by the substance, causing the particles to break free from their fixed positions and begin to move more freely. This results in a change in the physical state of the substance without a change in temperature.
Why does temperature no change during energy phase change?
During a phase change, the heat transferred to a substance is used to break intermolecular forces (latent heat), and thus the temperature of the substance does not change. The opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.
Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase

What change phase is heat energy absorbed by a substance?
liquid to gas
Why does heat applied to a substance change its temperature or make it change its phase?
compound of iron
Sensible heat involves a change in a substance's?
Sensible heat involves a change in a substance's temperature without a change in its phase. It is the heat exchange that causes a change in the temperature of a substance but does not result in a change of state (solid, liquid, gas).
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
What has to be added to a substance to cause a phase change?
Adding or removing energy in the form of heat is needed to cause a substance to undergo a phase change. This extra energy helps break the intermolecular forces holding the particles together in their current phase, allowing them to rearrange into a new phase with different properties.
What is the opposite of latent heat?
The opposite of latent heat is sensible heat. Sensible heat is the heat that causes a change in temperature of a substance without a change in phase.
