When determining the melting point or the freezing point of something....that is when they are used....
melting point and/or freezing point (they mean the same thing/are the same temperature)
Matter changes from solid to liquid at its melting point, because this change is called melting. Freezing point is about the same as melting point, but it can be slightly lower, so melting point should always be used.
They are the same thing. Most commonly the term melting point is used to describe the temperature at which a substance first co-exists in both a liquid and solid state. Freezing point is used usually to describe a substance that is usually liquid at room temperature, such as water. Conversely the term 'boiling point' refers to the first temperature at which the substance exists in both liquid and gaseous states.
Nope. It decreases. By lowering the melting/freezing point of water, salt (usually in the form of rock salt) can be used to keep roads and other surfaces clear of ice, as it requires lower temperatures than normal to freeze.
The melting point is the temperature at which a solid substance transitions to a liquid state. The drop melting point is a method of determining the melting point where a small amount of the substance is heated until it melts and then allowed to drop onto a solid surface to observe the melting point. Drop melting point is often used when the substance being tested has a high melting point or when observing the melting process is critical.
melting point and/or freezing point (they mean the same thing/are the same temperature)
Yes. Melting point is changing from a solid to liquid & freezing point is changing from a liquid to a solid. Both occur at the same temperature & these terms are usually used interchangably, although melting point is probably used more often than freezing point.
It's because substances have different boiling point and freezing point. By finding the exact boiling point and freezing point, you can identify a substance. Keep in mind that a material's melting point is the same as its freezing point. These are just different terms for the same thing, it just depends on whether energy is being removed from a substance (freezing) or if energy is being added to a substance (melting). The same thing also applies to the boiling/condensation point.
1063 °C(lit.) Freezing points and melting points generally can be used interchangeably. Scientific data is reported as the melting point or mp. Purity will also effect the freezing point but very useful in determining the purity of a substance.
A thermometer can be used to check the purity of a metal by measuring its melting or freezing point. Impurities in a metal can alter its melting point, so a pure metal should have a specific and consistent melting point. By comparing the measured melting point with the known melting point of the pure metal, the level of purity can be evaluated.
32 degrees Fahrenheit 'Freezing Point' is an improper statement (i think), and the term 'Melting point' is more commonly used. Everything has a different Freezing/Melting point, so I assume you mean the Freezing/Melting point of water? This is 0 degrees Celsius, or 32 degrees Fahrenheit, or 273.15 Kelvin.

the freezing point is 0 degrees celsius and the melting point is is above 0 degrees celsius
Salt is commonly used to lower the melting point of snow or ice. When salt is applied, it disrupts the hydrogen bonds between water molecules, reducing the freezing point and causing the ice to melt even in subzero temperatures.
Yes. The freezing point of water (melting point of ice) depends on both the temperature and the pressure. One easy way to lower the pressure is to add salt to ice. This lowers its freezing point and caused it to melt. Salt is spread on street and sidewalk ice in some areas to melt it and the addition of salt to ice is also used in the cooling of ice cream.
The temperature at which a solid, given sufficient heat, becomes a liquid. For a given substance, the melting point of its solid form is the same as the freezing point of its liquid form, and depends on such factors as the purity of the substance and the surrounding pressure. The melting point of ice at a pressure of one atmosphere is 0°C (32°F); that of iron is 1,535°C (2,795°F). See alsostate of matter.
