Can anyone answer this? A spacecraft in outer space increases its velocity by firing its rockets. How can hot gases escaping from its rocket engine change the velocity of the craft when there is nothing in space for the gases to push against?

The gases never push against the air. They push against the rocket motor itself, as the motor hurls the exhaust gases out the back at high speed.

the gases push on the engine as they expand before escaping out the tail pipe and i think you never knew this before now. you need to wake up and pay attention in class

For every action there is an equal and opposite reaction.

elasticity i believe, like when you fire a gun your arm pushes back by the force. sorry i can't be more detailed
