MATERIA
SÓLIDOS – LÍQUIDOS - GASES
Nancy Fredrickson 2003
SOLIDS - SOLIDOS
LIQUIDS - LIQUIDOS
GASESair - aire
helium – helio
oxygen, carbon dioxide, hydrogen, helium, etc.
SOLID to LIQUID = MELTING, it happens with some HEAT
LIQUID to GAS = EVAPORATION, with HEAT, FOR WATER: 100° C
GAS to LIQUID = CONDENSATION, WITH COLD
LIQUID to SOLID = FREEZING, with COLD, FOR WATER : 0 ° C
SOLIDO A LIQUIDO = FUSION, DERRITIRSE con algo de CALOR
LIQUIDO A GAS = EVAPORACION; PARA EL AGUA : 100° C
GAS A LIQUIDO = CONDENSACION CON FRIO
LIQUIDO A SOLIDO = CONGELACION PARA AGUA: 0°C
CON MUCHO FRIO
SOLID WATER IS … ICE!!
LIQUID WATER IS … WATER!!!
AS A GAS, WATER IS CALLED…
…WATER VAPOR!!!
AGUA SÓLIDA ES… HIELO.
AGUA LIQUIDA ES… AGUA.
COMO GAS, EL AGUA SE LLAMA… VAPOR DE AGUA.
WE CAN USE PHYSICAL PROPERTIES TO DESCRIBE &
IDENTIFY DIFFERENT SUBSTANCES…
COLOR, FLAVOR, SMELL, TEXTURE, MASS, MAGNETISM,
HARDNESS, BEING A CONDUCTOR OR INSULATOR, & THEIR BOILING AND MELTING
POINTS, ETC.
PODEMOS USAR PROPIEDADES FISICAS PARA INDENTIFICAR O
DESCRIBIR SUSTANCIAS DIFERENTES…
COLOR, SABOR, OLOR, TEXTURA, MASA,
MAGNETISMO, DUREZA, DE SER CONDUCTOR O AISLANTE, Y
SUS PUNTOS DE CONGELACION Y EBULLICION, ETC.
THESE ARE PHYSICAL CHANGES:
MELTING, FREEZING, CUT IN PIECES OR BROKEN,
EVAPORATION, CONDENSATION, ETC.
THE MATERIALS ARE STILL THE SAME THING…MELTED BUTTER OR CHOCOLATE, WATER VAPOR, ETC.
HAY CAMBIOS FISICOS :
DERRITIRSE, CONGELARSE, ROMPER O CORTAR EN PIEZAS, EVAPORARSE, CONDENSACION,
ETC.
LOS MATERIALES SIGUEN SIENDO IGUALES….MANTEQUILLA O
CHOCOLATE DERRITIDO, VAPOR DE AGUA, ETC.
CHEMICAL CHANGES INCLUDE BURNING, RUSTING OR OXIDATION
OF METALS LIKE OLD CARS, DIGESTION OF FOOD, ETC.
DURING CHEMICAL CHANGES, THE ORIGINAL SUBSTANCE CHANGES INTO SOMETHING COMPLETELY
DIFFERENT WITH DIFFERENT PROPERTIES.
CAMBIOS QUIMICOS INCLUYEN EL QUEMAR DE ALGO, OXIDACION DE
METALES COMO LOS CARROS VIEJOS, DIGESTION DE ALIMENTOS,
ETC.
EN CAMBIOS NO FISICOS, LA SUSTANCIA ORIGINAL CAMBIA EN ALGO TOTALMENTE NUEVO CON
PROPIEDADES DIFERENTES.
CON LO QUE SIGUE, INDENTIFICA
EL CAMBIO COMO FISICO O
QUIMICO…
WITH THE FOLLOWING, IDENTIFY
THE CHANGE AS PHYSICAL
OR CHEMICAL…
BROKEN GLASS - VIDRIO ROTO
IT’S STILL GLASS = PHYSICAL SIGUE SIENDO VIDRIO = FISICO
METAL CHANGES BY RUSTING = CHEMICAL CAMBIADO POR OXIDACION = QUIMICO
MELTED ICE CREAM = PHYSICAL CHANGE
HELADO DERRITIDO = CAMBIO FISICO
MELTED BUTTER = PHYSICAL CHANGE MANTEQUILLA DERRITIDA = CAMBIO FISICO
IT’S STILL BUTTER!
MOLDY BREAD, DECOMPOSING PAN CON MOHO, DESCOMPONIENDOSE
TOTAL CHANGE = CHEMICAL CAMBIO TOTAL = QUIMICO
GROSS & FUCHI
UN CAMBIO PERMANENTE = CAMBIO QUIMICO
PERMANENT CHANGE = CHEMICAL CHANGE
JITOMATE PICADO = CAMBIO FISICO
CHOPPED TOMATO = PHYSICAL CHANGE
IT’S STILL TOMATO!
