Why does the temperature of a substace remain constant even though energy is being added?

As a liquid is heated that energy is translated into kinetic energy of the molecules. At boiling point the kinetic energy of the hottest molecules is sufficient to drive them off into the gaseous state.
As more energy is added, more molecules are driven off. This carries large amounts of energy away, leaving the temperature of the liquid unchanged.
The temperature will not rise until all liquid has entered the gaseous state.

What happens to temperature as energy is added to a substance that is changing state?
The temperature remain constant during the phase changing.
What is the constant and the variables in Boyles law?
The constant k is a...constant specific for the system considered.
Does the frequency of a wave remain constant if the medium temperature and pressure do not change?
no
Why does temperature remain constant when wax solidifies?
the breaking of intermolecular bonds
Which thermodynamic process takes place at a constant temperature so that the internal energy of a system remains unchanged?
If a thermodynamic process takes place at a constant temperature it is called "isothermal". A word of caution however: the internal energy of a system may not remain the same in an isothermal process if the composition or phase changes; e.g. melting ice can be an isodthermal process but there is certainly a change in internal energy when it happens.
What happens to temperature as energy is added to a substance that is changing state?
The temperature remain constant during the phase changing.
What must remain constant for Boyle's law to be true?
1. A more correct name is Boyle-Mariotte law. 2. Only the temperature must remain constant.
The variable that Boyles law holds constant is?
Temperature remain constant.
Why does the temperature remain constant in the highlighted portion of the graph even thermal energy is being added?
the extra energy goes into breaking the bonds in the solid
When heating wax why does the temperature stay fairly constant?
When there is a change of state occuring (in this case from solid to liquid), temperature will remain constant. Energy is absorbed to weaken the intermolecular forces between the wax particles.
Why does the temperature remain constant in the highlighted portion of the graph even though thermal energy is being added?
the extra energy goes into breaking the bonds in the solid
What happen to the temperature during phase change?
The temperature remain constant.
Why does the temperature of any substance remain constant during the change of a state?
because energy is required to break the intermolecular forces in the molecule
Which variables must be kept constant for Boyle's law to hold?
The temperature must remain constant.
What is the constant and the variables in Boyles law?
The constant k is a...constant specific for the system considered.
What happens to the thermal energy of a substance during a physical change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
What happens to the temperature and the speed of the molecules when gas is compressed?
The temperature and speed remain constant.
