\"img_3167\"<\/a>La Fundaci\u00f3 Catalana per a la Recerca i la Innovaci\u00f3 impulsa la realitzaci\u00f3 de confer\u00e8ncies arreu de Catalunya en la setmana de la Ci\u00e8ncia. Avui a l’Auditori l’alumnat de 3r, 4t d’ESO i Batxillerat de Castellar han pogut compartir la confer\u00e8ncia “L’aire que respirem”\u00a0 que ens ha presentat en Xavier Gim\u00e9nez, professor titular del departament de Ci\u00e8ncies de Mat\u00e8ria, Qu\u00edmica i F\u00edsica de la Universitat de Barcelona.<\/p>\n

Amb imatges espectaculars en Xavier ens ha fet un viatge partint d’un fet tan quotidi\u00e0 com \u00e9s respirar. Qu\u00e8 entra dins nostre? Literalment, trilions de cossos tan petits que ens passen desapercebuts, tan nombrosos que en perdem el compte. Ens ha mostrat com algunes subst\u00e0ncies, com l\u2019oxigen, s\u00f3n prou conegudes; d\u2019altres, com l\u2019oz\u00f3, no ho s\u00f3n tant, per\u00f2 no per aix\u00f2 s\u00f3n menys rellevants.
\nEn aquest viatge del coneixement de l\u2019aire que respirem hem descobert aspectes tant interessants com:<\/p>\n

Per qu\u00e8 el lloc m\u00e9s sec de la Terra \u00e9s a l’Ant\u00e0rtida?<\/p>\n

Per qu\u00e8 fem servir nitrogen per inflar els airbags?<\/p>\n

Qu\u00e8 passa dins un llamp? Qu\u00e8 t\u00e9 a veure l’oz\u00f3 amb l’olor a\u00a0 terra mullada despr\u00e9s de la tempesta ?<\/p>\n

El forat d’oz\u00f3 t\u00e9 soluci\u00f3! Trobar les causes ha ajudat<\/p>\n

Qu\u00e8 t\u00e9 a veure el color de la flama amb la temperatura? Per qu\u00e8 acaba en punta? Com seria una flama sense gravetat?<\/p>\n

\"web3\"<\/a>Com \u00e9s el foc del Sol? Com ens protegeix el camp magn\u00e8tic de les radiacions?<\/p>\n

Com s\u00f3n d’importants les xemeneies marines per\u00a0 afavorir la vida submarina?<\/p>\n

Sabies que la pols del Sahara arriba i nodreix l’Amaz\u00f2nia?<\/p>\n

Amb aquestes i altres preguntes, en Xavier Gim\u00e9nez,ens ha atrapat.\u00a0 Ens ha apropat aspectes complexos de forma entenedora amb\u00a0 unes imatges i v\u00eddeos espectaculars.<\/p>\n","protected":false},"excerpt":{"rendered":"
