Aim: I am going to investigate which metals would be best to build a spacecraft that would survive on the surface of Venus. I will find out the maximum temperature on Venus, the melting point of each metal I test, the position of each metal in the reactivity series and the significant reactive substances in the atmosphere of Venus.

I will be provided with samples of: Magnesium

                                                     Aluminium

                                                     Zinc

       Nickel

    Iron

   Tin

        Copper

(In order of reactivity)

Information On Venus:

Astronomers refer to Venus as Earths sister planet. Both are similar size, mass, density and volume. Both formed about the same time and condensed out of the same nebula. However, during the last few years scientists have found that the kinship ends here. Venus is very different from the earth. It has no oceans and is surrounded by heavy atmosphere composed mainly of carbon dioxide with virtually no water vapour. Its clouds are composed of Sulfuric acid droplets. At the surface, the atmospheric pressure is 92 times that of the Earth’s sea level.

Venus, the second planet from the sun, is the hottest world in the Solar System. It is blanketed by a thick atmosphere that heats its surface like the inside of a greenhouse. It has a surface temperature of almost 900 degrees Fahrenheit (480 C).

Mass: 4.869e+24

Mass (Earth=1): 0.81476

Equatorial radius (km): 6,051.8

Equatorial radius (Earth=1): 0.9488

Metals- Melting Points:

Prediction: I think that the least reactive out of the metals given will be the most suitable for the spacecraft. This is Copper, it is a very unreactive metal. Not ...
