If a piston is pushed rapidly into a container of gas, what will happe...
When a piston is rapidly pushed into a container of gas, several changes occur in the gas molecules, leading to an increase in kinetic energy and temperature.
1. Compression of gas:
As the piston is pushed into the container, it compresses the gas. This compression reduces the volume of the gas, causing the gas molecules to come closer together.
2. Increase in kinetic energy:
The compression of gas increases the pressure inside the container. According to the ideal gas law, when the pressure of a gas increases, its temperature also increases, assuming the volume and the number of particles remain constant. This increase in pressure leads to an increase in the kinetic energy of the gas molecules.
3. Conservation of energy:
The increase in kinetic energy of the gas molecules is a result of the conservation of energy. When the piston is pushed rapidly, work is done on the gas by the external force applied to the piston. This work transfers energy to the gas, increasing its kinetic energy.
4. Temperature increase:
The increase in kinetic energy of the gas molecules corresponds to an increase in temperature. Temperature is a measure of the average kinetic energy of the gas particles. As the kinetic energy of the gas molecules increases, the average kinetic energy and hence the temperature of the gas increase.
5. Relationship between kinetic energy and temperature:
The kinetic energy of gas molecules is directly proportional to their temperature according to the kinetic theory of gases. Therefore, when the kinetic energy of the gas molecules increases, the temperature of the gas also increases.
In conclusion, when a piston is rapidly pushed into a container of gas, the kinetic energy of the gas molecules increases, leading to an increase in temperature. Therefore, the correct answer is option 'A' - both the kinetic energy and temperature of the gas increase.
