An open system is a system that has external interactions. Such interactions can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the concept.

A closed system allows only energy transfer but no transfer of mass. Example: a cup of coffee with a lid on it, or a simple water bottle. Isolated systems allow neither mass nor energy to flow through their boundaries. Example: a thermos flask.

7. Which of the following is true for a closed system? Explanation: For a closed system mass does not change.

Out of the given quantities, heat doesn’t describe the state of a system so it is not a thermodynamic property because a system doesn’t contain heat but only can transfer heat.

Mass, volume and pressure are extensive properties.

An intensive property does not depend on the system size or the amount of material in the system. Examples of intensive properties include temperature, T; refractive index, n; density, ρ; and hardness of an object, η.

Intensive properties: Properties which are independent of the amount of substance (or substances) present in the system are called intensive properties, e.g. pressure, density, temperature, viscosity, surface tension, refractive index, emf, chemical potential, sp. heat etc, These are intensive properties.

Mass and volume are examples of extensive properties. An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. Color, temperature, and solubility are examples of intensive properties.

Temperature is independent of the quantity of matter, hence it is an intensive variable. So the correct option is (D).

As the pH is the measure of concentration of H+ ions and as concentration is an intensive property so pH is also an intensive property. It’s intensive as it is mass independent. pH means negative log of concentration of hydroniun ions in the solution.

The ratio of two extensive properties is an intensive property. Force is an extensive property because F = m*a, and mass is extensive (as it depends on the number of particles). The product of an intensive and an extensive property is extensive.

An intensive property, is a physical property of a system that does not depend on the system size or the amount of material in the system. According to the definitions, density, pressure and temperature are intensive porperties and volume, internal energy are extensive properties.

Heat is an extensive property, and is proportional to the total energy of all atoms in an object. Temperature, on the other hand, is an intensive property, as it is proportional to the average energy per atom.

The heat capacity is therefore an extensive variable since a large quantity of matter will have a proportionally large heat capacity. Specific heat is therefore an intensive variable and has units of energy per mass per degree.

An extensive property is a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties. An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount.

All properties of matter are either extensive or intensive and either physical or chemical. Extensive properties, such as mass and volume, depend on the amount of matter that is being measured. Intensive properties, such as density and color, do not depend on the amount of matter.

Also, it can be noted that the ratio of any two extensive properties will yield an intensive property. For Example: the ratio of mass and volume is equal to the density….Extensive Properties.

The first difference is that Extensive Reading covers large area, while Intensive Reading covers narrower area. According to Graham Stanley, Extensive Reading involves students reading long texts or large quantities for general understanding, with the intention of enjoying the texts.

Matter Test

Properties that can be determined without changing the composition of a substance are referred to as physical properties. Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties.
