In Lesson 4.1, you learned that the machine used to fuel missions to Titan is not making enough liquid oxygen. We are waiting for a more detailed report from the Universal Space Agency. Before we receive the report, however—and now that you know how the liquid oxygen machine is supposed to work—what are some ideas you have about what could be causing it to malfunction?
Some ideas which could be causing it to malfunction is an increase in temperature of the titan.
What is Boiling point?This is defined as the constant temperature at which a liquid starts changing into gas.
Liquid oxygen has a high boiling point which means the Titan will have to be hotter for it to vapourize. This may have led to an increase in the production of oxygen gas and reduction in liquid oxygen production.

A motorcyclist is traveling at a speed of 72 km/h along a straight road. If the motorcyclist can slow down at a rate of 2 m/s2, what is the minimum stopping distance the motorcyclist needs?

In the “Liquid Oxygen” article, you read about how liquid oxygen is made and how it is needed to fuel rockets. The Universal Space Agency is planning to use liquid oxygen to fuel a rocket, carrying a new surface lander, to Titan. The launch window is short and needs to occur on a specific date or else the Universal Space Agency will need to wait for another year. But, there is a problem. The liquid oxygen machine is producing less liquid oxygen than normal. You have been asked to determine what is causing this problem.
In the space below, write down any initial ideas you may have about why the liquid oxygen machine is not working.
The hydrogen-oxygen reaction produces enormous heat, causing water vapour to expand and leave the engine nozzles at speeds of up to 10,000 miles per hour by using liquid nitrogen.
What is liquid oxygen ?The movement of liquid oxygen from one container to another can result in the formation of an oxygen-enriched atmosphere in the area of the containers. When a liquid oxygen container is not used for an extended period of time, a small quantity of oxygen is vented into the surrounding area. When the container is tipped over or put on its side, more oxygen is vented. If the container is stored in a confined area, this venting may result in an oxygen-enriched atmosphere.
What are fuel rockets ?Rockets generate thrust by rapidly expelling material rearward. The thrust generated can be calculated by multiplying the propellants' mass flow rate by their exhaust velocity relative to the rocket. (specific impulse). A rocket is accelerated by the weight of combusting gases against the combustion chamber and nozzle, rather than by "pushing" against the air behind or below it. Because of the lack of air pressure on the outside of the engine, rocket engines work best in space. It is also possible to accommodate a longer nozzle in space without experiencing flow separation.
