When an object is changing state form liquid to a gas the object is absorbing energy to allow its molecules to expand. it cant increase in temperature because it is using the energy that it is absorbing.

What else can I help you with?
A gas is most likely to change to the liquid phase when the pressure on the gas?
A gas is most likely to change to the liquid phase when the pressure on the gas is increased. This is because the same number of molecules will have less space to occupy.
When a solid melts its temperature remains constant So where does the heat energy go?
During the phase change from solid to liquid, the heat energy is used to break the intermolecular bonds holding the solid together, rather than increasing the temperature. This energy is absorbed as latent heat, allowing the solid to change its state while maintaining a constant temperature.
What one degree change in temperature on the Celsius temperature scale is equal to a one unit temperature change on the what temperature scale?
No, the "degrees" have the same name but are different sizes. (Celsius degrees are larger intervals than Fahrenheit degrees.) A change of 1 degree Celsius is the same as a change of 1.8 degrees Fahrenheit.
Melting point of water?
The melting point of a substance is the temperature at which solid state of a substance co exist in equilibrium with its liquid state. It is also called the freezing point (melting is the same process as freezing, just in the opposite direction, and so the temperature is identical).See Web LinksSee the Web Links for "Answers.com: Melting point" below for more information.The melting point is a point where a solid begins to heat and lose mass. It generally changes from a solid state to a liquid state.
At what temperature C and K are the same?
Both cannot be same.. Bcoz, *c and K scale have arithmetic relation... so it cant be same..
Does the temperature change while a phase chage is occurring?
No, the temperature does not change during a phase change. It remains constant until all the substance has undergone the phase change.
What happens to a substances temperature during a phase change?
stays the same
Could a phase graph with little temperature increase and a lot of heat be the same as latent heat?
Yes. Strictly speaking there should be no temperature change during a phase change.
Can molecules change phase and increase temperature at the same time?
Yes, it is possible.
Which stays the same when a substance switches from liquid to gas?
During the phase change, the temperature stays the same.
What rule can you state about the relationship between phase changes and temperature?
As the temperature increases, the phases change from having the slowest amount of molecules to having the fastest amount of molecules (solid-liquid-gas)
What phase change mean?
changes from one state to another without a change in chemical composition
What happens to energy added during a phase change?
The added energy is used in the phase change to break intermolecular bonds.It is used for the phase change. ~ APEX
What happens when heat is added to a system?
When heat is added to a system, the temperature increases, unless there is a phase change taking place. In that case, temperature remains the same, and the only observable difference is the phase change.
How can the temperature of a substance remain the same even if the substance is absorbing thermal enerrgy?
The temperature of a substance can remain the same during absorbing thermal energy if the substance is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed thermal energy goes into breaking intermolecular bonds rather than increasing the temperature. Once the phase change is complete, the temperature will resume rising as the substance absorbs more thermal energy.
Which phase change temperatures are identical on the phase diagram?
The temperature for melting and freezing is the same. The temperature for vaporization (boiling) and condensation is also identical. Refer to the related link for a diagram that illustrates phase changes.
How can a matter change from solid state to liquid state and reverse the process?
At a unique temperature, called the "freezing point", for each pure substance at a constant pressure, a solid form of the substance can change from solid to liquid phase by absorbing heat energy from its environment without raising the temperature of the substance, and, at the same temperature and pressure, a liquid phase of the same substance, can solidify without changing its temperature if it can transfer heat energy to the external environment.
