well temp., pressure, volume, and mass
Measurable Properties of Gases(1) The characteristics of gases are described fully in terms of four parameters or measurable properties :(i) The volume, V, of the gas.
(ii) Its pressure, P
(iii) Its temperature, T
(iv) The amount of the gas (i.e., mass or number of moles).
(2) Gas Volume : (i) Since gases occupy the entire space available to them, the measurement of volume of a gas only requires a measurement of the container confining the gas.
(ii) Volume is expressed in litres (L), millilitres (mL) or cubic centimetres (cm3) or cubic metres (m3).
(iii) 1 L = 1000mL; 1 mL = 10--3; 1 L = 1 dm3 = 10--3 m3
1 m3 = 103 dm3 = 106cm3 = 106mL = 103L
(3) Gas Mass : (i) The mass of a gas can be determined by weighing the container in which the gas is enclosed and again weighing the container after removing the gas. The difference between the two weights gives the mass of the gas.
(ii) The mass of the gas is related to the number of moles of the gas i.e.
moles of gas (n) = Mass in grams/Molar mass = m/M
(4) Temperature : (i) Gases expand on increasing the temperature. If temperature is increased twice, the square of the velocity (v2) also increases two times.
(ii) Temperature is measured in centigrade degree (oC) or celsius degree with the help of thermometers. Temperature is also measured in Fahrenheit (Fo).
(iii) S.I. unit of temperature is kelvin (K) or absolute degree.
K = oC + 273
(iv) Relation between F and oC is oC/5 = Fo--32/9
(5) Pressure : (i) Pressure of the gas is the force exerted by the gas per unit area of the walls of the container in all directions. Thus, Pressure (P) = Force(F)/Area(A) = Mass(m)×Acceleration(a)/Area(a)
(ii) Pressure exerted by a gas is due to kinetic energy (KE = 1/2 mv2) of the molecules. Kinetic energy of the gas molecules increases, as the temperature is increased. Thus, Pressure of a gas ∝ Temperature (T).

Why liquid or gas considered a physical prperty?
Liquid and gas are considered physical properties because they describe the state of matter of a substance. Physical properties are characteristics of a substance that can be observed or measured without changing the substance's composition, and whether a substance is in a liquid or gas state is one such observable property.
Are physical properties observable?
Yes, physical properties are observable characteristics of matter that can be measured or detected without altering the composition of the substance. These properties include attributes such as color, shape, size, density, and conductivity.
Which gases has bleaching property?
Chlorine gas and sulfur dioxide gas are examples of gases that have bleaching properties. Chlorine gas is commonly used in the bleaching of paper and textiles, while sulfur dioxide gas is often used as a bleaching agent in the food industry.
The phenotype of an organism does what?
The phenotype of an organism is the physical expression of its genetic traits, influenced by both genetic and environmental factors. It includes observable characteristics such as behavior, appearance, and chemical properties. The phenotype is a result of interactions between an organism's genes and its environment.
What are the observable properties that scientist use to identify minerals?
Observable properties are: color and streak, luster, cleavage and fracture (crystalline structure), and hardness.
WHAT IS AN OBSERVABLE PROPERTY IN SCIENCE?
An observable property in science is a characteristic or behavior of a substance or system that can be detected or measured using the senses or scientific instruments. Observable properties provide information about the nature or state of the object being studied. Examples include color, size, shape, temperature, and weight.
Describe anyone of the four phases of matter. What are the external observable properties?
In the liquid phase, particles have more freedom of movement compared to solid but less than gas. Liquids take the shape of their container and have a definite volume. External observable properties include surface tension, viscosity, and the ability to flow.
What are five physical properties of elements?
A physical property of an element refers to an observable property that does not change the composition of the element. Five examples of physical properties are: melting point, odor, boiling point, color and density.
What are the observable physical properties of matter?

What are the observable properties of solution?
The observable properties of a solution include transparency, color, taste, odor, boiling point, freezing point, and concentration. These properties can vary depending on the composition of the solute and solvent in the solution.
Why liquid or gas considered a physical prperty?
Liquid and gas are considered physical properties because they describe the state of matter of a substance. Physical properties are characteristics of a substance that can be observed or measured without changing the substance's composition, and whether a substance is in a liquid or gas state is one such observable property.
What are observable properties of solutions?
Observable properties of solutions include color, odor, taste, clarity, boiling point, freezing point, density, and conductivity. These properties can be used to characterize and identify different types of solutions.
What are the 4 properties of gas?
Examples are: density, flammability, boiling point, melting point.
What are 2 details that support that matter has properties that can be observed?
Matter have 2 Properties:Extensive properties depend on the amount of matter that is being measured. These include mass and volume.Intensive properties do not depend on the amount of matter. These include density and color
Do you have non-examples for physical properties?
Non-examples of physical properties include emotions (such as happiness or sadness), thoughts (like beliefs or opinions), and actions (such as running or singing). These examples do not fall under the category of physical properties because they are related to internal states, mental processes, or behaviors rather than observable characteristics of matter.
What are some chemical properties of gas?
Examples: chemical reactivity, flammability, tendency to explode, etc.
