During boiling all the heat supplied to the liquid is used up in overcoming the intermolecular forces present among the molecules of the liquid. That is why the temperature of the liquid does not change.

Why doesn't the temperature of water change during melting?
The melting and freezing temperature of water are the same: 0o C; thus, both water and ice can exist at this temperature. Lets say a block of ice is starting at a temperature below the melting point. As the temperature of the ice rises, the heat energy being transfered into it goes to raising its temperature, but when the temperature reaches the melting point, the heat energy introduced does not go into raising the temperature but instead into breaking the bonds holding it as a solid. The ice-water mixture will remain at 0o until all of the ice has fully melted. Only after all of the ice has melted does the heat energy go into heating the water.
What is the energy required to go from liquid to gas called?
The latent heat of vaporization
Why temperature remains constant during the process of melting or boiling?
This is because of latent heat. When a substance is being melted, heat is supplied to the solid until its melting point is reached. When the solid reaches that temperature, any additional heat energy is used - not to raise its temperature - but to cause the phase to change from solid to liquid. The amount of energy required (per unit mass) is the latent heat of melting (or freezing, when the process is reversed) for that substance. When the phase change is complete, any further heat energy supplied will, once again, go towards raising the temperature.The same thing happens at the boiling point except that this time it is the latent heat of evaporation/condensation.
Where does the heat energy from a hot cup of tea go?
ah doi of course by losing heat tothe surrounding lah omg
When the Kelvin temperature of an enclosed gas doubles what do the particles of the gas do?
Temperature is proportional to energy and energy of gas particles is related to their velocity via E= 1/2mv2. So if the temperature doubles then the velocity of the individual particles increases by (4dE/m)1/2 =v
Materials with a high specific heat can absorb a lot of energy and show little change in temperature?
Yes. Specific heat capacity is the amount of heat energy required to change the temperature of the material, so a material with high specific heat needs a lot of heat energy for its temperature to go up.
What is it called when heat can go from cooler to warmer temperatures?
"heat" can not go from colder to warmer temperatures. Heat is not an object, it's energy. Temperature is simply a measurement of how much heat an object possess.
In which way does heat flow?
When a hotter/colder object touches the opposite heat of it, then the colder ones thermal energy will go up and the hotter ones thermal energy will go down until then have then same temperature.the cold air is pushed down and the hot air forced up.Answer'Heat' is defined as energy in transit from a higher temperature to a lower temperature.
Where does the energy go since heat of vaporization does not result in a temperature change?
It increases the potential energy of the molecules, since they separate from each other.
Where is there no temperature change when a solid heated into liquid at its melting point?
Phase transitions cost energy, so that energy doesn't go into heat
Does matter have heat energy when it is cold?
Because molecules in matter are always moving, virtually all matter has some heat energy, even when it seems cold to you. Matter that seems cold is merely not as hot as objects near it, or as hot as your hand. It still has temperature and thus heat energy. As long as its temperature is above -459.7°, it has heat energy.

What does the latent heat of fusion represent?
The energy required to melt a substance. (Apex)
When a solid melts its temperature remains constant So where does the heat energy go?
Temperature indicate kinetic energy density in molecular vibration. Over phase change, energy go to motion and fight against molecular interaction make it mobile.Liquid is more mobile in compare to solidVapour is more mobile in compare to liquid.Molecular vibration (temperature) stay the same while the energy input go to mobility (latent heat).Read more: When_a_solid_melts_its_temperature_remains_same_so_where_does_the_temperature_goes
When a solid melts and temperature remains the same so where does that heat energy go?
It increases the molecular energy of the substance, the molecules of a liquid move faster than those of a solid at the same temperature.
Thermal energy transferred between objects which have different temperature?
A transfer of heat (H) energy does not occur without a temperature differential. If the two objects had different amounts of H then a transfer would indeed occur. In this case heat would flow from a higher to lower temperature object.
Does heating always increase temperature?
No. For example when you heat boiling water, its temperature remains the same. the thermal energy will go to breaking the attraction between the atoms
