Specific volume of water

It is, therefore, frequently convenient to identify the volume per unit mass of a material as its "specific volume:" v = (V/m). The specific volume is the reciprocal of the density of the material, which is the mass per unit volume: r = (1/v) = (m/V).

What is the specific volume of water and ice?

The molar heat of fusion of ice is 6.025 kJ/mole at 273K and 1 bar pressure.

Does water have a specific volume?

The output specific volume is given as cm3/g, ft3/lb, gal(US liq)/lb and ft3/sl. The specific volume of water depends on temperature as shown below: See Water and Heavy Water - thermodynamic properties.

How do you measure specific volume?

To calculate specific volume you need to know the volume (V) and the mass (m). Specific volume equals volume divided by mass. Typically, volume is measured in cubic meters (m3), and mass is measured in kilograms. Specific volume is then calculated as volume divided by mass.

What is the specific value of water?

Water's specific heat power is 4.2 joules per gram per Celsius degree or 1 calory per gram per Celsius degree.

Why do we calculate specific volume?

Specific volume is most often used in engineering and in thermodynamics calculations for physics and chemistry. It is used to make predictions about the behavior of gases when conditions change.

What is unit of specific volume?

Specific volume is a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit is the meter cubed per kilogram (m 3 /kg or m 3 · kg -1 ).

What is specific volume example?

For example, the specific volume of water is 1.0 L/kg. This means that 1 kg of water takes up 1 liter of space. A liter of water can fit into a standard water bottle, such as a Nalgene. In contrast, the specific volume of air is 820 L/kg.

What is the specific volume of water at its critical point?

Water has a critical specific volume of 0.003155 m3/kg.

What is the difference between volume and specific volume?

Since the mass and volume are directly related to each other under static conditions, we can define a new property called the specific volume which is equal to the volume divided by the mass. Specific volume is an intensive property of the gas, as shown in our example.

Is specific volume the same as volume?

Summary – Volume vs Specific Volume Volume is a thermodynamic property of a substance. Specific volume is the volume of a unit mass of a substance. The difference between volume and specific volume is that volume is an extensive property whereas specific volume is an intensive property.

What is the specific weight of water?

A common unit of measurement for water's density is gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm3). Actually, the exact density of water is not really 1 g/ml, but rather a bit less (very, very little less), at 0.9998395 g/ml at 4.0° Celsius (39.2° Fahrenheit).

What are the 3 methods used to calculate volume?

To illustrate the effects of precision on data, volumes will be determined by three different methods: geometrically (measuring lengths); water displacement; and pycnometry.

How is specific volume experimentally determined?

The most accurate modern method is the Magnetic Levitation Densimeter, which works by suspending a weight from a balance plate using magnetic forces. The gas whose density is to be measured is then introduced to the chamber at a known pressure and temperature.

What are the 4 methods used to find volume?

Different Ways to Find Volume

Solve for Volume by Space. All physical objects occupy space, and you can find the volume for some of them by measuring their physical dimensions.
Solve for Volume by Density and Mass. Density is defined as an object's mass per a given unit of volume. ...
Solve for Volume by Displacement.

What is the specific property of water?

Unique properties of water Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more electronegative, meaning that it is better than hydrogen at attracting electrons. Water is an excellent solvent.

What is water's specific?

Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius. For water, this amount is one calorie, or 4.184 Joules.

What are specific water properties?

The five main properties of water are its high polarity, high specific heat, high heat of vaporization, low density as a solid, and attraction to other polar molecules.

Does specific volume depend on mass?

The mass depends on the volume and, in turn, the volume depends on the mass. If we maintain the pressure and temperature of this gas and fill an object which can vary its volume, like a balloon, or a cylinder with a sliding end, the final volume depends directly on the amount of the gas that we inject.

Does pressure affect specific volume?

The Relationship between Pressure and Volume: Boyle's Law. As the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together.
