blurted this. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume. They only obey the ideal gas law if pressure is low or temperature is high. Kelvin scale of temperature is regarded as better scale than Celsius. Why does a gas have no definite shape and no definite volume? Solids and liquids have volumes that do not change easily. Conclusion : Gases take up any volume and hence all gases have no definite volume. Figure \(\PageIndex{3}\): A Representation of the Solid, Liquid, and Gas States. Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. The change from solid to liquid usually does not significantly change the volume of a substance. Liquids have no definite shape and volume. anor277 Mar 17, 2018 Because a gas … hope it will help you mark as brainlist answer plz. Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. Pressure. Solids and liquids have volumes that do not change easily. gases Do solids have definite shape and fixed volume? And being spread out like this allows them to move around freely. Do the gases have a definite shape and a fixed volume? New questions in Chemistry. Gases. If the particles of a substance have enough energy to completely overcome intermolecular interactions, then the particles can separate from each other and move about randomly in space. Gases have lower density than other states of matter, such as solids and liquids.There is a … The forces between the molecules are weaker so the gases are not held as closely together . Use the Kinetic theory to explain compressibility. Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume … Liquids do have a definite shape but have definite volume while gases neither have fixed shape nor fixed volume. Question 20. A gas has a volume that changes to match the volume of its container. https://www.quora.com/Does-a-gas-have-a-definite-volume-Why-or-why-not Every matter (solid, liquid and gas) in the universe have mass and volume.If you want to feel that take a flexible plastic bottle. Figure \(\PageIndex{3}\) A representation of the solid, liquid, and gas states. Experiment Process and steps: Visit any petrol pump and view different places where CNG (Compressed Natural Gas) is stored. Consequently, real gases do not adhere to the ideal gas law. Chemistry Phases of Matter Properties of Solids, Liquids, and Gases. Do gases have mass? Gas particles glide easily past one another. Why can gases change volume but liquids Cannot? Solids and liquids have volumes that do not change easily. However, the change from a liquid to a gas significantly increases the volume of a substance, by a factor of 1,000 or more. If a gas is not in a container, it will spread out indefinitely. 27 Related Question Answers Found … which sentence explains this? 2 Answers Cris John Mar 17, 2018 Because its shape and volume always change. Regards d. liquids have a definite volume..... What is true about the volume of displaced fluid for an object that is completely submerged? If we take two solid objects, say a pen and a book, and put them in different containers, do you find any change in their. (B) A gas is a substance with no definite volume and no definite shape. Diffusivity. A gas is a substance with no definite volume and no definite shape. A gas, on the other hand, has a volume that changes to match the volume of its container. Solids and liquids have volumes that do not change easily. Hence, solids have a d e f i n i t e v o l u m e. A gas is a substance with no definite volume. A gas, on the other hand, has a vol- ume that changes to match the volume of its container. Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. Everything around us is made up of tiny particles. A gas has no shape or definite volume because of the amount of energy it has. The reason is that the particles are so much farther apart in a gaseous state. Why? Experiment: A gas takes up the volume of any enclosed space filling it up completely. Compressibility and Expandability. In shifting to a defense policy based upon the concept of "flexible response," president kennedy was indicating that he … The molecules in a gas are very far apart compared with the molecules in … The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume. ( Something like that.) The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. However, the change from a liquid to a gas significantly increases the volume of a substance, by a factor of 1,000 or more. Gases do have a definite volume. Relation with kinetic theory and ideal gases Boyle's law states that at constant temperature the volume of a given mass of a dry gas is inversely proportional to its pressure. A gas, on the other hand, has a vol- ume that changes to match the volume of its container. There are many gas laws derived from observation and experiment over the centuries, and these have establlished that a gas (or mixture of gases) will fill the volume of any container uniformly. Answer: As it has a wide range of measurement and temperature in kelvin scale always has a positive sign, hence regarded as better … The point I am trying to make is that the gas-filled balloon has an indefinite shape, and it is modified by the shape that the balloon-folder creates. In other words, the particles have a definite volume and mass. Furthermore, does gas have a definite volume and shape? When you look at molecules of the gas, they are always bouncing from each other, not really forming a bond with each other. 1 ; View Full Answer The internulcear distance between gas particles is very high and force of attraction is least therefore gas particles to move in any direction, hence do not have fixed volume. You need to get permission from petrol pump for observation. Required Equipment and Material: It is observatory experiment only. Using the equation pV=nRT. Gases do not have a definite shape or volume. Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. Based on chemical properties it has been classified into element, compound, and mixture. Volume of gas is that one mole of gas should occupy at STP and NTP. Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. A gas, on the other hand, has a vol- ume that changes to match the volume of its container. a) gases do not have a definite volume. A gas is a substance with no definite volume and no definite shape.
