Constru\u00efm un vaixell de vapor casol\u00e0!<\/strong><\/p>\n

A la nostra \u00faltima experi\u00e8ncia al laboratori, hem aconseguit construir i posar en marxa un vaixell de vapor casol\u00e0!<\/p>\n

Com ho hem fet?<\/strong><\/h3>\n

Construcci\u00f3 del casc<\/strong><\/h4>\n
    \n
  1. Estirem i retallem un bric de llet perqu\u00e8 quedi un rectangle.<\/li>\n
  2. El retallem i dobleguem seguint un patr\u00f3 per obtenir la forma desitjada.<\/li>\n
  3. Dobleguem i enganxem totes les parts amb silicona per formar l\u2019estructura b\u00e0sica.<\/li>\n
  4. A cinc cent\u00edmetres de la punta, tallem un petit rectangle d’1,5 x 0,5 cm que ens servir\u00e0 per fixar el motor.<\/li>\n<\/ol>\n

    Creaci\u00f3 del motor<\/strong><\/h4>\n
      \n
    1. Retallem una franja de 5 cm d\u2019una llauna i la dobleguem per la meitat.<\/li>\n
    2. Marquem una l\u00ednia a 1 cm del marge i dobleguem aquesta part cap a dins.<\/li>\n
    3. Obrim lleugerament una de les parts doblegades i hi introdu\u00efm dues palletes retallades per la meitat.<\/li>\n
    4. Fixem els costats doblegats i retirem les palletes.<\/li>\n
    5. Col\u00b7loquem dues palletes senceres al forat restant i les fixem.<\/li>\n
    6. Fixem el motor sota el vaixell utilitzant el rectangle pr\u00e8viament retallat.<\/li>\n
    7. Enganxem una meitat de palleta i unim les palletes del motor a aquesta.<\/li>\n
    8. Finalment, col\u00b7loquem una vela sota el motor per escalfar l\u2019aigua.<\/li>\n<\/ol>\n

      Qu\u00e8 passa quan el posem en marxa?<\/strong><\/h3>\n

      Quan encenem la vela, aquesta escalfa l\u2019aigua, que es converteix en vapor i surt propulsant el vaixell cap endavant. Aquest fen\u00f2men ens permet entendre la tercera llei de Newton<\/strong> (acci\u00f3-reacci\u00f3) i el proc\u00e9s de vaporitzaci\u00f3<\/strong>.<\/p>\n

      A m\u00e9s, hem vist que aquest m\u00e8tode de propulsi\u00f3 \u00e9s una alternativa m\u00e9s sostenible respecte als m\u00e8todes convencionals emprats en la ind\u00fastria i els vehicles.<\/p>\n

      Us deixem algunes fotos:<\/p>\n
