Why is mass an extensive property explain?
Extensive Properties An extensive property is a property that depends on the amount of matter in a sample. The mass of an object is a measure of the amount of matter that an object contains. A small sample of a certain type of matter will have a small mass, while a larger sample will have a greater mass.
Is molecular weight an extensive property?
An extensive property is a property that changes when the size of the sample changes. Examples are mass, volume, length, and total charge. Examples are temperature, color, hardness, melting point, boiling point, pressure, molecular weight, and density.
Why are mass and volume extensive properties?
Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity.
Why is heat extensive?
Heat energy is the internal energy of a substance. This includes kinetic and potential energy. It is impossible to accurately measure all the kinetic energy of the moving particles in a substance. The more particles you have, the more heat energy you have, thus heat energy is an extensive property.
Is weight intensive or extensive?
Intensive properties do not depend on the quantity of matter. Examples include density, state of matter, and temperature. Extensive properties do depend on sample size. Examples include volume, mass, and size.
Why mass and volume belongs to extensive property of matter?
What is the property of weight?
weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. Because of all the mass in the universe, each point of space has a property called the gravitational field at that point, numerically equal to the acceleration of gravity at that point.
Why enthalpy is an extensive property?
The more of the substance(s) you have, the more heat can be absorbed or released for a given change. For example, vaporising 100 g of water takes double the amount of energy as the same process for 50 g of water. This makes enthalpy an extensive property.
Which is extensive property of system?
An extensive property of a system depends on the system size or the amount of matter in the system. If the value of the property of a system is equal to the sum of the values for the parts of the system then such a property is called extensive property. Volume, energy, and mass are examples of extensive properties.
