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 acid and base react what happens to the temperature?
When an acid and a base react, there is a possibility of an exothermic or endothermic reaction occurring, depending on the specific acids and bases involved. An exothermic reaction releases heat energy, leading to an increase in temperature, while an endothermic reaction absorbs heat energy, causing a decrease in temperature.
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.
What is the engery required to go from liquid to gas called?
The energy needed to go from a liquid to a gas is referred to as heat of vaporization.

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
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.
Does heating always increase temperature?
Not necessarily. Heating may not always increase temperature if the heat is absorbed by a phase change, such as melting or evaporating a substance. In these cases, the heat energy is used to break intermolecular bonds rather than increase the temperature.
When a solid melts and temperature remains the same so where does that heat energy go?
When a solid melts and temperature remains constant, the heat energy is used to overcome the intermolecular forces holding the particles together, breaking the bonds and allowing the solid to change to a liquid state. This heat energy absorbed during the phase change is called latent heat.
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.
What does the latent heat of fusion represent?
The energy required to melt a substance. (Apex)
Where does the heat energy from a freezer go?
The heat energy from a freezer is removed by the refrigeration system, which transfers it outside the freezer. The compressor compresses the refrigerant gas, raising its temperature, and then releases it outside where it dissipates into the surrounding environment. This cycle allows the freezer to maintain its cold temperature inside.
Which direction does heat transfer occur: does heat go to cold or does cold go to heat?
Heat transfer occurs from hot to cold. Heat always moves from a higher temperature to a lower temperature.
