not necessary, it's related to melting point of liquid and the room temperature.
Heat is added to a solid to make a liquid... this is called melting. some additional liquid (water,ethanol,acid…) also change solid into a liquid.
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
In that case, the liquid may eventually change to a gas.
None - heat is evolved, not required.
Heat is added to a solid to make a liquid... this is called melting. some additional liquid (water,ethanol,acid…) also change solid into a liquid.
heat
Evaporation is the process where a liquid turns into a gas, not a solid. The change from a liquid to a solid is called solidification or freezing, where the particles of a liquid come together to form a solid structure as the temperature decreases.
Solid --> Liquid. Liquid -> Gas. Solid --> Gas.
Chemicals chAnge their state or form when energy is added ie heaT OR COLD CHANGE TO SOLID LIQUID OR GAS
Physical change can occur when energy is added or removed. For example, adding heat energy can cause water to change from a solid to a liquid (melting), while removing heat energy can cause water to change from a liquid to a solid (freezing). These changes do not alter the chemical composition of the substance.
Thermal (heat) energy must be added or removed in order to cause a change of state.
To change the state of water from solid (ice) to liquid (water), heat must be added to increase the temperature above 0 degrees Celsius. To change water from liquid to gas (water vapor), heat must be added to increase the temperature above 100 degrees Celsius.
The heat of fusion refers to the energy required to change a substance from a solid to a liquid at its melting point. For water to change from ice to liquid water, heat needs to be added, making the heat of fusion a positive value.
The complete subject of the sentence is "To change a liquid to a solid."
The change of a substance from solid to liquid is called melting. This process occurs when heat is added to the solid, causing its particles to gain enough energy to break free from their fixed positions and move more freely, transitioning it to a liquid state.
That's the heat of fusion.
