Is ice melting a chemical or physical property?
Physical, chemical is one that affects the chemical make up of the substance.
What point does it become a liquid?
The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.
How do impurities affect the melting point of compound?
effects that impurities have on melting point iof a pre compound. I learned that it is because the impurities "defect" the crystal lattice of the compound. A pure compound is a structure of high molecular symmetry. An impurity is rather assymetrical, or is a poorly organized structure. If the impurites are present with the pure compound, the melting point will deviate because melting point is also dependent on the high symmetry and organization of molecular structures,
Is the melting of table salt physical or chemical?
The melting point is a physical property of materials.
Does boiling point and melting point occur at the same temperature?
It depends on the substance and the pressure. For most substances at atmospheric pressure, the boiling point is much higher than the melting point. However, some things, like nitrogen and carbon dioxide, do not have any liquid phase at atmospheric pressure--they go directly from solid to gas and vice-versa.
What is the melting temperature of a molecule?
A molecule is not an unique entity. It is common to any substance. Any no. of atom which combine together by chemical bonds form a molecule. The melting point of any molecule depends upon its chemical composition.
What is the substances melting point the same as?
A substance's melting point is the temperature at which it changes from a solid to a liquid state. It is unique to each substance and does not necessarily match the melting point of any other substance.
What is a melting point.?
A melting point refers to a temperature that any given solid substance will melt.
If its melting point is 112c is it a physical or chemical property of sulfur?
The melting point of sulfur at 112°C is a physical property. This property describes how the substance changes from a solid to a liquid state under specific conditions, without any change in its chemical composition.
Is melting point a chemical property or a physical?
It is a physical property, so is boiling point.
Is NaCl the substance with the lowest melting point is?
NaCl, common table salt, has a rather high melting point. The substance with the lowest melting point is helium. Helium has no solid phase, it melts at any temperature above absolute zero.
For any pure substance the boiling point and melting point will always remain?
The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.
Is ice melting a chemical or physical property?
Physical, chemical is one that affects the chemical make up of the substance.
What point does it become a liquid?
The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.
Are melting point unique to elements?
Yes, the melting point of a substance is unique and specific to that substance. It is the temperature at which a solid material changes into a liquid at atmospheric pressure. Each element or compound has its own distinct melting point.
What is used to identify the purity of a substance?
The purity of any substance can be checked through Melting Point,Boiling Point or Chromatography. As A pure substance has a set and exact melting point and boiling point and a pure substance shows only one spot on the chromatogram.
The temperature at which a substance changes from a liquid to a solid is the?
This is called the melting point, and the temperature is different for every material. For pure water, it is zero degrees Celsius, or 32 degrees Fahrenheit. Determining the melting point of any material is an important clue to determining what the material is.
