L\u00cdQUID, S\u00d2LID I GAS\u00d3S.<\/p>\n

Els tres estats de la mat\u00e8ria els hem presentat col\u00b7locant en un got una beguda gasosa amb un gla\u00e7\u00f3. D’aquesta manera hem trobat el l\u00edquid del refresc, el gas de les bombolles i el s\u00f2lid del gel.<\/p>\n

ELS S\u00d2LIDS COL\u00b7LOIDES<\/p>\n

Aquest tipus de s\u00f2lids s\u00f3n aquells que estan a mig cam\u00ed entre un s\u00f2lid i un l\u00edquid. Per a demostrar-ho hem donat a cada nen una mica de gelatina i els hem explicat que quan est\u00e0 freda podem observar que es comporta com un s\u00f2lid,\u00a0 per\u00f2 en el moment que ens la posem a la boca, amb l’escalfor corporal,\u00a0 es fon i es transforma en l\u00edquid.<\/p>\n

\"\"<\/a><\/p>\n

AIGUA FREDA I AIGUA CALENTA<\/p>\n

Les mol\u00e8cules a l’aigua\u00a0\u00a0freda i a l’aigua calenta no es mouen de la mateixa manera. Per comprovar-ho hem abocat unes gotes de colorant alimentari a un recipient amb\u00a0 aigua freda i hem repetit l’operaci\u00f3 amb l’aigua calenta.<\/p>\n

Aix\u00f2 ens ha perm\u00e8s arribar a la seg\u00fcent conclusi\u00f3:\u00a0 la disoluci\u00f3 en aigua calenta \u00e9s molt m\u00e9s r\u00e0pida.<\/p>\n
