When a substance undergoes fusion, it transitions from a solid state to a liquid state, typically due to an increase in temperature. This process occurs when the thermal energy of the substance overcomes the intermolecular forces holding its particles in a fixed position. As a result, the structure becomes more disordered, allowing the particles to move freely and flow. Fusion is commonly referred to as melting, and it is a key phase change in the study of thermodynamics.
What else can I help you with?
This is the rate at which a substance undergoes a chemical change?
This is called reaction rate.
What happens when a pure substance undergoes a chemical changes?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
What is the name of the celestial body that undergoes nuclear fusion?
The Sun is the celestial body that undergoes nuclear fusion, where hydrogen atoms combine to form helium, releasing energy in the process.
When does helium fusion begin in a star?
Hydrogen undergoes nuclear fusion to form helium at a temperature of 107 K
What is a substance that undergoes a chemical change produces a new substance with new?
This substance is called reactant.

What is wrong with this statement, "As a substance freezes, it absorbs energy equal to its enthalpy of fusion"?
There is nothing inherently wrong with the statement "As a substance freezes, it absorbs energy equal to its enthalpy of fusion." In fact, this statement is a well-established scientific principle known as the Enthalpy of Fusion. When a substance changes from a liquid phase to a solid phase (freezing), it undergoes a phase change that requires a specific amount of energy to overcome the intermolecular forces holding the substance together. This energy absorbed is known as the Enthalpy of Fusion, and it is dependent on the substance and specific conditions. Therefore, this statement accurately describes the process of freezing and provides important information about how substances behave during phase changes.
What is the substance that undergoes a chemical reaction?
A reactant.
