## why is energy an extensive property

Energy, volume and enthalpy are all extensive properties. Their value depends on the mass of the system. For example, the enthalpy of a certain mass of a gas is doubled if the mass is doubled; the enthalpy of a system that consists of several parts is equal to the sum of the enthalpies of the parts. ## Is energy a extensive?

Energy, volume and enthalpy are all extensive properties. Their value depends on the mass of the system.

## Is energy a property?

Energy is a quantitative propertyquantitative propertyQuantity or amount is a property that can exist as a multitude or magnitude, which illustrate discontinuity and continuity. Quantities can be compared in terms of "more", "less", or "equal", or by assigning a numerical value multiple of a unit of measurement.https://en.wikipedia.org › wiki › QuantityQuantity – Wikipedia of a system that depends on the motion and interactions of matter and radiation within that system.

## Is the free energy extensive or intensive?

Free energy is an extensive property, meaning that its magnitude depends on the amount of a substance in a given thermodynamic state.

## How do you know if a property is extensive?

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.Mar 17, 2022

## What makes something an extensive property?

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.Mar 17, 2022

## Is change in internal energy intensive or extensive?

Internal energy is an extensive property—that is, its magnitude depends on the amount of substance in a given state.

## Is internal energy extensive?

Internal energy is an extensive property—that is, its magnitude depends on the amount of substance in a given state.

## Is internal energy a state variable?

The internal energy is a state variable, just like the temperature or the pressure. The first law of thermodynamics defines the internal energy (E) as equal to the difference of the heat transfer (Q) into a system and the work (W) done by the system.

## Why is energy an extensive property?

Energy, volume and enthalpy are all extensive properties. Their value depends on the mass of the system. For example, the enthalpy of a certain mass of a gas is doubled if the mass is doubled; the enthalpy of a system that consists of several parts is equal to the sum of the enthalpies of the parts.

## Why internal energy is extensive state variable?

The internal energy is an extensive property: it depends on the size of the system, or on the amount of substance it contains. At any temperature greater than absolute zero, microscopic potential energy and kinetic energy are constantly converted into one another, but the sum remains constant in an isolated system (cf.

## Is specific energy an extensive property?

Intensive properties are properties that do not depend on the quantity of matter. For example, pressure and temperature are intensive properties. Energy, volume and enthalpy are all extensive properties. Their value depends on the mass of the system.

## Is specific an intensive property?

Specific properties are intensive because they exist at a point. For instance, specific volume is simply the reciprocal of density.

## Is specific energy intensive or extensive?

Specific energy is an intensive property, whereas energy and mass are extensive properties. The SI unit for specific energy is the joule per kilogram.
