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.

How is stoichemetry used to calculate energy released when a mass of liquid freezes?
Stoichiometry is used to calculate the energy released when a mass of liquid freezes by applying the concept of heat transfer during phase changes. The heat released can be determined using the formula ( Q = m \cdot \Delta H_f ), where ( Q ) is the heat energy, ( m ) is the mass of the liquid, and ( \Delta H_f ) is the enthalpy of fusion (the amount of energy released when the substance freezes). By knowing the mass of the liquid and its enthalpy of fusion, one can calculate the total energy released during the freezing process.
What common substance freezes at room temperature?
One common substance that freezes at room temperature is water. At 0 degrees Celsius (32 degrees Fahrenheit), water freezes and turns into ice.
How is the triangle h fusion used to calculate the energy released when a mass of liquid freezes?
The triangle h fusion, often represented as ΔH_fus, refers to the enthalpy change associated with the phase transition from liquid to solid at a substance's melting/freezing point. When calculating the energy released when a mass of liquid freezes, you multiply the mass of the liquid by the specific enthalpy of fusion (ΔH_fus). This product gives the total energy released during the freezing process, as the liquid loses energy to transition into a solid state.
How is stoichiometry used to calculate energy released when I mass of liquid freezes?
Stoichiometry can be used to calculate the energy released during the freezing of a liquid by calculating the moles of the liquid that freeze and then using the enthalpy of fusion of the substance (given in kJ/mol) to determine the total energy released during the process. The energy released can be found by multiplying the moles of liquid that freeze by the enthalpy of fusion value.
What is a substance that boils at 100 degree and freezes at 0 degrees?
Water is a substance that boils at 100 degrees Celsius and freezes at 0 degrees Celsius.
How does the motion and arrangement of particles is a substance change as the substance freezes?
As a substance freezes, the particles slow down and move closer together, forming a more ordered arrangement. This results in a decrease in the substance's volume and a transition from a liquid to a solid state.
Does a substance gain energy when it freezes?
When a substance freezes, it releases energy as it changes from a higher-energy state (liquid) to a lower-energy state (solid). The energy is released as heat into the surroundings.
When water freezes it absorbs what?
When water freezes, it absorbs heat energy from its surroundings to undergo a phase change from a liquid to a solid. This absorbed heat energy is used to break the intermolecular bonds between water molecules, allowing them to form a more structured solid lattice arrangement.
What is the change in state when a substance freezes?
Type your answer here..the shape and volume
When a substance freezes does its thermal energy decrease?
Yes, when a substance freezes, its thermal energy decreases since the molecules lose kinetic energy and slow down as they transition from a liquid to a solid state.
Describe how the motion and arrangement of particles in a substance as the substance freezes?
The particles get attracted to each other, forming a solid.
Why does water as it freezes absorbs heat from the fruit in the cellar?
It dosent. The fruit will not be frozen because the sugar in it will be acting as an antifreze.
