That's the amount of heat you have to add to the solid form at the melting temperature in order to melt it to the liquid form at the same temperature. Looking at it the other way: It's the amount of heat you have to remove from the liquid at the freezing temperature in order to freeze it solid at the same temperature.

Latent heat means the inherent, hidden heat. When we place a vessel of water on a burning stove having a thermometer within, initially the temperature level would rise in the thermometer because heat is taken up by water from the stove. But when the temperature becomes nearly 100oC the temperature would remain at the same level. Do you say that heat is not taken by the water from the flame of the stove? Certainly not. Then why is it so? Here, a new phenomenon starts taking place. Every unit (say 1 kg) of water starts getting converted from liquid form into gas form, that is, steam. So heat is totally utilized for that change of state. Hence the level of the thermometer stands still. This amount of heat sole utilized to have this change of state is called latent heat of steam. This means all heat drawn from the stove is available as inherent heat within steam. When steam condenses back into water, the hidden heat would come out. Same way, you can think about giving heat to ice. If suppose the initial temperature of the ice is some -10oC, then temperature would rise up to 0oC and there after though heat is continuously passed on to the ice solid, the temperature will come to stand still. Now, the heat is used to melt every unit of ice into its liquid form (water). This heat is termed as latent heat of melting. Or even we say this as latent heat of fusion. The above two are the examples of the change of state. From liquid to gas and from solid to liquid. Apart from these, water would be changed into water vapour even at the room temperature. This phenomenon is due to the shooting off the water molecules right from the water medium into the atmosphere (air medium). But, you cannot see any fall in temperature due to this escape. Here molecules gain energy from the surroundings and hence molecules could come out so without making any change in its temperature. This is termed as latent heat of vapourisation. (this would be better instead evaporation)
kinetic energy turns into heat energy which heat's the water SLOWLY (keep frantically moving) ;D
Use really clean equipment. Heat some water in a beaker so that it will dissolve more solute. Dissolve all that it will hold, to make sure add excess. Decant the liquid into another beaker allow no crystals to be transferred to the new beaker. Allow to cool slowly. Do not agitate. The cool solution will be supersaturated.
the proper way to heat a liquid in a test tube is by putting it in open flame.
No. Just add enough water to fill the basin 1/4 of the way. The juices from the roast will add more liquid.
Heat rises. Warmer water has a less dense structure than does cold water, so the cold water literally "pushes" its way down to the bottom of a liquid, forcing the warmer water up.
# First you take a heat proof bowl. # Next add water all the way to the top. # Finaly add magma and there you go.
That's the amount of heat you have to add to the solid form at the melting temperature in order to melt it to the liquid form at the same temperature.

It is not recommended to add bleach to the water in your hydrocollator heat pack as it can damage the materials and affect its performance. Regular cleaning with mild soap and water, followed by thorough rinsing, is a safer and more effective way to keep your heat pack clean.
One way to add heat to a substance without raising its temperature is by changing its state of matter. This process, known as phase change, involves adding heat energy to a substance to change it from a solid to a liquid or from a liquid to a gas. During this phase change, the temperature of the substance remains constant until the phase change is complete.
Not the way you probably mean. Anything that is cooler than its surroundings "absorbs" heat.
Yes. Heat causes expansion in all three states of matter (gas, liquid, and solid) with the exception of water.
The only way to 'place' water on a hot burner is when it is a solid (ice), or as a container of liquid water Naturally, the hot burner would melt it into a liquid and rapidly boid it away into water vapor (gas)
The heat is stored in water vapour is latent heat.Latent heat describes energy that is not stored as the internal energy (i.e. temperature) of an object but in its phase state.For example, in the atmosphere heat that is transported by an air parcel that contains more water vapor than its surroundings. Because energy is needed to turn water into water vapor, water vapor is a way for a body to store energy (along with potential energy, kinetic energy, and sensible heat). If the water vapor is returned to a liquid or solid phase (by condensation or sublimation), the stored energy is released as sensible heat.
