Why does temperature falls below when sodium chloride is added to them?
Referring to salt being added to crushed ice perhaps? When this is done, the salt causes the ice to melt. Melting actually requires heat (latent heat of liquifaction) and so the melting ice draws heat from its surroundings, thus lowering the temperature of its surroundings. A mixture of crushed ice and salt is frequently used in the laboratory and referred to as "freezing mixture".
What happens during a phase change as heat is added to a water sample?
As heat is added to a water sample during a phase change, all of that heat goes into changing the phase, say from solid ice, to liquid water, and as a consequence, the TEMPERATURE of the sampleDOES NOT CHANGE.
Why does ice melt in warm water?
ice melts in warm water because ice is slow moving molecules so slow they practically vibrate wen heat is added is like Coffee it wakes them up and energizes them cousing them to melt into a liquid
If you have cramps do you use heat or ice?
Ice
What happens to the heat when water solidifies into ice it absorbed or evolved?
I think it is evolved because if the heat is absorbed then the latent heat will be given to the matter( ice) then the ice will start melting
What is added to ice to make it melt and how does this affect the molecules in the ice?
Heat is added to ice to make it melt.
What is added to ice to make it change from a solid to a liquid?
heat
What is solid to a gas and is heat added or removed?
Of course heat is added because you are turning solid which is like ice to gas which is water vapour !!

What happens when ice is added to water?
its gets cold Actually the ice gets warmer. Its the water that gets cold.
What is added until ice becomes a liquid?
The addition of thermal energy, or heat, if you prefer, will turn solid water (ice) into a liquid by melting it.
Why does salt ice melt slower than ice with no salt?
The freezing point of water is lower with added salts; the heat of solution is released.
What has to be added in order for solid ice to melt into liquid water or liquid water to evaporate into steam?
heat
Can heat be added to a solid liquid and gas without changing in teperature?
That is possible when there is a change of state. For example, if you have ice at its melting point, or a mixture of ice and water at its melting point, if you add heat, the energy will be used to melt the ice, not to increase the temperature.
Does water always turn into ice when its cold?
no. Ice can evaporate into a gas by melting into water and turning into a gas when more heat is added. Gas can be hot or cold
Why energy is needed to melt ice and how this is explained by the structure of ice and water?
Think about how ice melts into water. By adding heat! Heat is a form of energy, and by adding heat, we can change ice to water. This is explained well by the structures of ice and water. Ice is a solid, and its molecules form rigid networks with space between molecules and are not easily broken. Water is a liquid, and its molecules are constantly moving around one another, leaving little space between molecules. Therefore, when heat energy is added to ice, the rigid bonds between molecules in the ice break, and they are free to move like a liquid.
What is thermal energy of melting?
its the latent heat of fusion or simply Enthalpy of fusion.ie,this heat is absorbed or added at melting temperature.for eg latent heat of fusion of ice= 6.02 KJ/mol (80cal/gm).
