What is a gas simple definition?
1 : a fluid (such as air) that has neither independent shape nor volume but tends to expand indefinitely. 2a : a combustible gas or gaseous mixture for fuel or lighting especially : natural gas.
What is gas answer?
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy. The particles exert more force on the interior volume of the container.
What is gas with example?
The most common example of a gas is air (the air we breathe is a gas). It can also be considered as a mixture of many gases such as nitrogen, oxygen and carbon dioxide.
What is gas give two example?
Examples of gases are oxygen at room temperature (approximately 20 ºC or 68 ºF), hydrogen at room temperature, and water at standard atmospheric pressure and a temperature above 100 ºC or 212 ºF. When a sample of matter in the gaseous state is heated, the atoms or molecules gain kinetic energy and move more rapidly.
What is gas Kid definition?
Gases are air-like substances that can move around freely or they might flow to fit a container. They don’t have a shape either. Similar to liquids, gases can actually flow, but gases won’t stay put as solids or liquids do. They move around all the time.
What is gas in science grade 3?
Gases, like liquids, have no definite shape but take the shape of their container. Unlike liquids and solids, gases do not have a definite volume but spread out to fill the entire container in which they are placed.
What are five properties of gases?
Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form. Compressibility. An internal combustion engine provides a good example of the ease with which gases can be compressed.
What are some examples of gas in gas?
Air
What’s the difference between gas and liquid gas?
Both liquids and gases belong to a state of matter called plasma because of the shared characteristic of flowing.
What is definite of a gas?
A gas has neither a definite volume nor a definite shape. Some gases can be seen and felt, while others are intangible for human beings. Examples of gases are air, oxygen, and helium.
