Why the specific heat capacity of a substance depends upon phase?
Wiki User
∙ 14y ago
The capacity for an object to be heated and retain heat is determined by its phase because of the way the different phases of matter move. The more freely the molecules are able to move around (like in a gas), the more likely the excited (or warmed up) molecules will leave the group, causing the heat to dispress more quickly.

Which phase always fills its container?
when a substance is in liquid phase
What does a phase diagram provide?
"A phase diagram is a graph of pressure versus temperature that shows in which phase a substance exists under different condition of temperature and pressure" -Glencoe Chemistry Book
Does volume change when substance changes states?
Yes. Usually when a substance freezes, or becomes a solid, it will decrease in volume, causing an increase in density. Water is an exception, which is less dense when it freezes/becomes solid.
Melting is an example of a?
Melting is an example of a phase change. The substance is going from the solid state to the liquid state.
What is the change of a substance from one physical state to another?
change of state
What does a phase diagram show for a substance?
A phase diagram shows if a substance is going to be a solid gas, or liquid at a combination of pressure and temperature. It states what phase of matter a substance is at a specific temperature.
In which temperature water has maximum specific heat capacity?
The specific heat capacity of water does not change much within-phase (ie, as a solid it has one specific heat capacity, as a liquid/gas it has another)
The phase of matter depends on what?
Heat and pressure are the two main factors that determine a substance's current phase.With high heat a substance's phase drifts toward the gaseous phase while freezing temperatures cause it to move toward its solid phase. With pressure it is the opposite. Higher pressures push the substance toward its solid phase, while lower pressures will encourage the substance to evaporate into its gaseous phase.
Thermal energy depends on what two factors?
I would say that an object's thermal energy depends on four factors: its mass, its temperature, its heat capacity, and any phase changes, for example from solid to liquid.I would say that an object's thermal energy depends on four factors: its mass, its temperature, its heat capacity, and any phase changes, for example from solid to liquid.I would say that an object's thermal energy depends on four factors: its mass, its temperature, its heat capacity, and any phase changes, for example from solid to liquid.I would say that an object's thermal energy depends on four factors: its mass, its temperature, its heat capacity, and any phase changes, for example from solid to liquid.
Are properties that can be observed or measured without changing a substance into a new substance?
Yes, these are thy physical properties of substances.
Which phase of a substance can exist when the pressure is less than the pressure of the triple point?
This depends on the temperature.
What is the phase of a substance at 2.0 ATM and 100 degrees Celsius?
The answer depends on the substance. Some substances will be solid, some liquid and some gas.
What do you call the combination of solid liquid and gas?
This only occurs at a specific point on the phase diagram of a substance called the "triple point." This point corresponds to a certain pressure and temperature for an individual substance, since these are the axis values for a phase diagram.
What do the lines on a phase diagram represent?
The lines show where a phase changes happens to a substance -
What is the phase relationship of load voltage to load current?
that depends on the circuit. as you have not described it, no specific answer can be given.
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.
