An ideal gas cannot be...
A. condensed
B. cooled
C. heated
D. compressed
The answer is condensed.
True :)
An ideal gas cannot be condensed or cooled. To understand this, let's first understand what an ideal gas is. An ideal gas is a concept in physics that describes a theoretical gas composed of a collection of randomly moving particles, such as atoms or molecules. These particles are assumed to have no volume and do not experience any intermolecular forces, which makes them different from real gases.
Now, let's analyze the options:
A. Condensed: An ideal gas cannot be condensed because in an ideal gas, the particles are assumed to have no volume. Therefore, they cannot be brought closer together to form a liquid or solid state, which is the process of condensation.
B. Cooled: An ideal gas can certainly be cooled. Cooling a gas refers to reducing its temperature. In an ideal gas, temperature is related to the average kinetic energy of the particles. By reducing their kinetic energy, the temperature decreases, and the gas is cooled. So, cooling an ideal gas is possible.
C. Heated: An ideal gas can also be heated. Heating a gas means increasing its temperature by adding energy to it. In an ideal gas, the temperature is directly proportional to the average kinetic energy of the particles. Adding energy to the gas increases the kinetic energy of the particles, raising the temperature.
D. Compressed: An ideal gas can be compressed. Compression refers to reducing the volume of the gas. Although ideal gas particles are assumed to have no volume, they can still be compressed in a practical sense. This can be achieved by applying external pressure on the gas, forcing the particles closer together.
Therefore, the correct option is A. An ideal gas cannot be condensed.
