Concept explainers
Interpretation:
The meaning of compression and expansion of gas needs to be explained.
Concept introduction:
Compression and expansion of gas is the property of gas which is explained by the kinetic molecular theory.
Answer to Problem 36A
On the basis of kinetic molecular theory, gas particles are easily compressed due to small volume while random motion enables gases to expand if pressure is not considered.
Explanation of Solution
Compression and expansion is the change in volume with respect to pressure which is given by the ideal gas equation. This equation is given by formula as follows:
Here, p is pressure, V is volume, n is number of moles and T temperature. In expansion, the gas expanded at room temperature. The pressure decreases when compression takes place but it increases in expansion. Also, volume of the compressed gas is less than the expanded gas.
