TYPES OF SOLIDS

TYPES OF SOLIDS l l CRYSTALLINE SOLID- SOLIDS THAT ARE MADE UP OF CRYSTALS. MELTS AT DISTINCT TEMP. EXAMPLE- SALT, SUGAR, SNOW AMORPHOUS SOLID- PARTICLES ARE NOT ARRANGED IN A REGULAR PATTERN. DOES NOT MELT AT DISTINCT TEMP. EXAMPLE- PLASTICS RUBBER AND GLASS

SALT IS A _______

Types of SOLIDS give 3 more examples

Plastics can harm marine life. Why?

LIQUIDS HAS A DEFINITE VOLUME l TAKES THE SHAPE OF ITS CONTAINER l KEY- PARTICLES IN A LIQUID ARE MORE LOOSELY CONNECTED AND CAN COLLIDE WITH AND MOVE PAST ONE ANOTHER. l FLUID- A SUBSTANCE THAT FLOWS l EX- WATER, OIL, MILK l

PROPERTIES OF LIQUIDS l l l SURFACE TENSION- AN INWARD PULL AMONG THE MOLECULES OF A LIQUID THAT BRINGS THE MOLECULES CLOSER TOGETHER. EX- A FULL GLASS OF WATER CAN BE HIGHER THAN THE RIM. VISCOSITY-LIQUIDS RESISTANCE TO FLOWING EX- HIGH VISCOSITY- SLOW FLOW- HONEY EX- LOW VISCOSITY- FAST FLOW- WATER

What other types are there?

GASES l l l NO DEFINITE VOLUME NO DEFINITE SHAPE IS A FLUID –FLOWS KEY- PARTICLES SPREAD APART MOVING IN ALL DIRECTIONS FILLING THE SPACE OF ITS CONTAINER. KEY- THE ATOMS AND MOLECULES ARE FREE TO MOVE INDEPENDENTLY AND COLLIDE FREQUENTLY. EX- AIR, HELIUM, NITROGEN.
