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?
During melting or boiling, the temperature remains constant because the heat energy is being used to break the bonds between the molecules of the substance, rather than increasing the kinetic energy of the molecules. Once all the bonds are broken, the temperature will start to increase again.
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.
Where does the heat energy from a hot cup of tea go?
ah doi of course by losing heat tothe surrounding lah omg
Materials with a high specific heat can absorb a lot of energy and show little change in temperature?
Yes, materials with a high specific heat can absorb a significant amount of energy when heated because they require more energy to raise their temperature compared to materials with lower specific heat. This property makes them useful for applications like heat storage and temperature regulation.
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 required to go from liquid to gas is called heat of vaporization. This is the amount of energy needed to change a substance from a liquid into a gas at constant temperature and pressure.

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?
Heat flows from areas of high temperature to areas of low temperature. This flow can occur through three main mechanisms: conduction (direct contact and transfer of heat), convection (transfer of heat via a fluid like air or water), and radiation (transfer of heat through electromagnetic waves).
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.
When a solid melts its temperature remains same so where does the temperature goes?
The temperature remains constant during the melting process because the heat energy is used to break the bonds holding the solid together, rather than raising the temperature of the material. This energy is known as latent heat of fusion. Once the solid is fully melted, the temperature can then increase.
