Els alumnes de CS hem fet alguns experiments per descobrir que \u00e9s la pressi\u00f3 atmosf\u00e8rica o la pressi\u00f3 de l’aire.<\/p>\n

Ara us explicarem qu\u00e8 \u00e9s la pressi\u00f3 atmosf\u00e8rica.<\/p>\n

Com podr\u00edeu ficar un ou a dins d’una ampolla sense tocar-lo? La pressi\u00f3 de l’aire \u00e9s la soluci\u00f3.<\/p>\n

La pressi\u00f3 de l’aire \u00e9s capa\u00e7 de emp\u00e8nyer l’ou si es crema un tros de paper a dins de l’ampolla. Quan s’escalfa l’aire de dins de l’ampolla la pressi\u00f3 de dins l’ampolla es redueix perqu\u00e8 en consumeix l’oxigen de forma r\u00e0pida.<\/p>\n

Com que hi ha l’ou al forat de l’ampolla la pressi\u00f3 exterior (m\u00e9s alta) l’empeny cap dins.<\/p>\n

L’ou acaba a dins de l’ampolla amb una forma molt m\u00e9s allargada que la seva forma normal, al cap d’una estona l’ou recupera la seva forma normal.<\/p>\n
