For each pair of terms explain how the meanings of the terms differ melting and freezeing?
Melting is the process of changing a solid into a liquid, typically due to an increase in temperature. Freezing is the opposite process, where a liquid changes into a solid due to a decrease in temperature. Melting involves the breaking of intermolecular forces holding the solid together, while freezing involves the formation of these forces to create a solid structure.
Which term is defined as the process by which a substance changes state from solid to liquid-?
melting
Is boiling the reverse of freezing?
no it is not melting is the reverse of freezing
What is the physical change of a solid at the melting point?
It turns from a solid to a liquid
Explain what happens to the temperature of an ice cube as it melts?
Temperature of melting iceis a constant property: it does not change during melting (stays 0oC, this is even one of the the defined value of the Celsius temperature scale)(for any other melting solid the same is valid at each melting point temperature)
Explain why there is this pattern in melting points for francium?
The melting point of francium is not measured, only supposed by comparison with the melting points of the other alkali metals.
Which material has higer melting point NaCl or sugar explain?
Generally inorganic ionic salts have higher melting points than organic materials; the bonds are stronger.
What is the point of Pewter What is the melting point of Acrylic Explain in detail why the acrylic does not melt when the molten pewter is poured into the mould Why is MDF and hardboard used to make t?
what is the melting point of pewter
Explain why burning butter is a chemical change but melting is not?
Melting: change of phase, a physical phenomenon without change of the composition. Burning: a reaction of oxydation, a change of composition - a chemical change.
Is America truly is a melting pot in 2011 explain.?
yes, never has there been such a collection of different races and cultures in one country.
Explain whyIn Group 17 HF has abnormally high melting and boiling points as compared to other hydrides of the group?
Hydrogen bonding.
Explain how the salinity of water in polar regions varies seasonally?
Surface salinity in polar regions varies seasonally due to the formation and melting of sea ice.
Explain melting and freezing according to the kintic theory of matter?
When heat is supplied to a solid, the kinetic energy of the particles increases, they move away from each other
In science explain why more salt will disslove in the water when its temperature is greater?
Sodium Chloride (table salt) is an ionic compound that has a high melting point. The higher the temperature, the more you have reached its melting point, that means the higher the temperature the more the salt will be dissolved. (as long as the temperature is about 801 degrease Celsius, or 1474 degrease Fahrenheit, because that is table salts melting point.)

What is a soild changing into a liquid called?
melting
Explain why the expansion of rock is important in the formation of magma.?
The melting temperature of materials is affected by the pressure they are under. So when "rock" in the Earth's mantle experiences a decrease in confining pressure, not only does it expand, it's melting temperature drops. If the melting temperature of the material drops below the background (also known as the in-situ) temperature, then melting will occur and in this case magma will form.This typically occurs in the earth where hot upwelling mantle material experiences a decrease in confining pressure (as there is less and less overlying material as it rises) which ultimately causes adiabatic or decompression melting.
