The Hoffmann voltameter apparatus for electrolysing water, invented by August Wilhelm von Hoffmann (1818-1892) When a current is ran through the HV gaseous oxygen forms at the anode and gaseous hydrogen at the cathode. Each gas displaces water and collects at the top of the 2 outer tubes • Pure water doesn’t conduct electricity but sulphuric acid when added to water conducts electricity • The modern name for the Hoffmann voltameter is electrochemical coulometer. As we are making our own Hoffmann voltameter we have found another homemade version which we can use ideas from. - First invented in 1866. As on Earth, weather conditions on Mars depend on location and season. In general, Mars is cooler, breezier, and much drier than Earth. The warmest temperatures usually occur in the southern subtropical latitudes during late summer and may get up to the freezing point at midday. Coolest temperatures occur in the polar regions where it remains close to 190F below freezing for months at a time. Because of the cold temperatures the atmosphere cannot hold much water so clouds tend to be thinner and do not really produce much rain. On the other side, such dry conditions allow dust particles to remain in the atmosphere for a long time. These dust particles are lifted off the surface by cyclone force winds. Occasionally the entire planet is filled by dust storms and surface features can be completely obscured. This is where the name the red planet comes from because the large amount of land is red from the dirt. Mars rover the Phoenix was the first to spot ice on the planet mars. C2C stands for Concept to Creation; it is an annual science program which targets year 9 students to create something. This year we are focusing on ‘life on mars’, we have been given the task to create something that will help up see a future on mars, where we may be able to live. As NASA has recently discovered that there is evidence of water (H2o) on mars, we can hope for a future on the once thought to be dead planet as water is what we need for the human race to survive. Our group is made up of four people. Chloe Stockdale, Claire McAuley, Sonja Davey and Siobhan Bee. Our Idea Main Idea: To convert water into Carbon Dioxide. We came up with the idea because even though we can land on mars, it will be pointless to try and live there if we have no oxygen to breathe. About Mars - Diameter: 4,221 miles (6,794 km) - Mass: 0.11 of Earths mass - Rotation Period: 1.03 Earth days - Inclination of Equator to Orbit: 25.2 degrees - Average Orbital Speed: 15 miles per second (24.1 km) - Distance from the sun: 142 million miles (228 million km) Mars Mars is the fourth planet from the sun in our solar system; it’s often described as the red planet. The planet Mars is named after the roman god of war. The reason for the reddish appearance is the iron oxide on the planet’s surface being swept up by cyclonic winds making the planet appear red from the outside. Mars in also has a very thin atmosphere, so that means not much, if any oxygen is in its atmosphere. Mars also has the highest mountain in our solar system called ‘Olympus Mons’, it also has the largest canyon which spreads across 40% of the planet. Martian days consist of 24 Earth hours and 37 minutes. The planets temperature reaches -200 degrees Celsius in winter and -20 degrees Celsius in summer. The wide range is due to the thin atmosphere. Mars has many dust storms and they occur most when Mars is closest to the sun. Voltameter Images Our Logo “Galax” for Galaxy, we chose it because our mars exploration in our galaxy. “C” – C for Chloe and Claire, two members of our team. “S” – S for Siobhan and Sonja, the remaining members of our team. These are some images of the Hoffman Voltameter. We have used this design to create a Voltameter of our own. Logo made by Chloe Stockdale using Photoshop.
