Predict what will happen to the unknown substance when the wall is removed to produce the final condition depending on whether the unknown substance is a solid, liquid, or a gas? If the unknown is a solid, no change will occur because the particles occupy fixed positions and do not take the shape of the container. If the unknown is a liquid, no change will occur because the particles take the shape of the container but do not fill the entire volume. If the unknown is a gas, the substance will expand to completely fill the entire container because the particles are free to move independently. A If the unknown is a solid, no change will occur because the particles cannot move fast enough the fill the entire container. If the unknown is a liquid, the particles will expand and fill the entire container. If the unknown is a gas, the particles will remain in the same side of the container, but they will take the shape of the container. If the unknown is a solid, no change will occur because the particles take the shape of the container but do not fill the entire volume. C If the unknown is a liquid, no change will occur because the particles occupy fixed positions. If the unknown is a gas, the substance will expand to completely fill the entire container because the particles are free to move independently. If the unknown is a solid, removing the wall will cause it to become a liquid and take the shape of the container. If the unknown is a liquid, removing the wall will cause the liquid to become a gas and completely fill the container. If the unknown is a gas, no change will occur except the gas particles will expand and fill the entire container. D O Time Rem ©2021 Illuminate Education TM Inc.
Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.
