Why does the temp of water not increase during a phase change?
These are phase changes - All the energy that is added at this time is used to change the phase of the substance.
Sometimes heat energy is added but the temperature stays the same when is this?
During a phase change.
What has to be added to a substance to cause a phase change?
Heat energy must be added to or subtracted from a substance to cause a phase change.
What must occur to the heat energy of an object in order of a phase change of the state of matter?
heat is added
How do you change liquid to gas?
To change the phase of a system from liquid to gas, the total system energy must be increased (heat added) to the point where every atom or molecule has sufficient energy to escape the liquid system.
What happens to the 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 to the energy added during the phase change?
When energy is added during a phase change the energy is used to break molecular bonds.

How does the the energy of a system change during a phase change?
energy is either absorbed or released during a phase change

As heat is added to a substance undergoing a phase change. why does the temperature remain?
Basically what it comes down to is the substance that is left behind during the phase change (say the liquid when it is changing to a vapor) has a lower internal energy than it had before the phase change started. To maintain the substance at its original temperature, an equivalent amount of energy must be added to make up for the loss of internal energy due to the phase change. (Conservation of Energy)The energy added in this case is heat, which in turn causes more molecules of the substance to change phases and lowers the internal energy & the process repeats. This is why the temperature remains constant as you add heat to a substance during a phase change. Once the phase change is completed the added heat will eventually cause the temperature to rise in the new phase of the substance. Hope this explanation helps. It's kind of hard to explain without a basic knowledge of thermodynamics.
What happens to a substances temperature during a phase change?
stays the same
Does the energy content of a substance change during a phase change?
Yes, but not the temperature.
