A shock wave is moving into still air in a shock tube. Which one of th...
Explanation:
When a shock wave moves into still air in a shock tube, several changes occur in the air. One of these changes is an increase in the static temperature, which is the temperature of the air at rest. The total temperature also increases as a result of the shock wave passing through the air.
Static Temperature:
The static temperature of a gas is a measure of its molecular kinetic energy. When a shock wave passes through a gas, it compresses the gas and increases its static temperature. This increase in temperature is due to the conversion of the kinetic energy of the shock wave into thermal energy. Therefore, the static temperature of the air increases as the shock wave passes through it.
Total Temperature:
The total temperature of a gas is the sum of its static temperature and its kinetic temperature, which is a measure of the velocity of the gas molecules. When a shock wave passes through a gas, it increases the kinetic temperature of the gas. This increase in kinetic temperature contributes to an increase in the total temperature of the gas.
Effect of Shock Wave:
When a shock wave moves into still air in a shock tube, it compresses the air and increases its static pressure. This increase in static pressure is accompanied by an increase in the static temperature of the air. The shock wave also increases the kinetic temperature of the air, which contributes to an increase in the total temperature of the air.
Therefore, in this scenario, both the static temperature and the total temperature of the air increase as a result of the shock wave passing through it. The correct answer is option 'B': static temperature increases, total temperature increases.
