SOLIDS - SOLIDOS

LIQUIDS - LIQUIDOS

oxygen, carbon dioxide, hydrogen, helium, etc. GASES air - 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

ICE!! SOLID WATER IS … 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.

WITH THE FOLLOWING, IDENTIFY THE CHANGE AS PHYSICAL OR CHEMICAL… CON LO QUE SIGUE, INDENTIFICA EL CAMBIO COMO FISICO O QUIMICO…

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

DYED HAIR - CABELLO PINTADO

UN CAMBIO PERMANENTE = CAMBIO QUIMICO PERMANENT CHANGE = CHEMICAL CHANGE UN CAMBIO PERMANENTE = CAMBIO QUIMICO

JITOMATE PICADO = CAMBIO FISICO CHOPPED TOMATO = PHYSICAL CHANGE IT’S STILL TOMATO! JITOMATE PICADO = CAMBIO FISICO
