Supersonic air going through an incipient shock wave will decrease its speed and
- decrease temperature and increase density.
- increase temperature and decrease density.
- increase temperature and increase density.
Explanation from PART66Online
A shock wave is a compression: as supersonic air passes through it the flow is abruptly decelerated, and static pressure, temperature and density all rise across the shock. The kinetic energy lost in slowing the flow appears as a rise in temperature, while compression raises the density.
