INTRODUCTION. SOLIDS‚ LIQUIDS AND GASES have properties that are use to describe how they behave‚ e.g. for solids it has a definite shape‚ you can hold a solid rock in your hand. You can push on a solid brick wall. Scientists say a solid is something that has shape. A solid resists any change in its shape. TASKS 2. LOOK AT THE PICTURES BELOW FOR SOLID‚ LIQUID AND GAS AND WRITE DOWN THREE PROPERTIES OF EACH? Wood as a Solid. Solid has a fixed shape Its particles are tightly held together

shape and volume. In a liquid‚ the particles have weaker attraction and are not as close to each other as solids. They can move around in all directions so liquid does not have a defined shape‚ but their movements are still limited by attractions between particles. Their movements are also limited by the walls of their containers‚ which is why liquids will take the shape of it’s container. Particles of gases are further apart from each other than particles in solids and liquids and their attraction

of diameter d = 3500mm and 5km long is used to pump water. An obstruction plugs the pipe at an unknown location so that no liquid can flow. A piston is placed in one end of the pipe and slides (without leakage)‚ compressing the water in the pipe. The pressure increases 855 k Pa when the piston is moved a distance of 734mm into the pipe. If the temperature of the liquid =300 C‚ how far down the pipe would you estimate the obstruction to be? 3- Derive an expression for the capillary height change

Accuracy and precision of the results will be estimated‚ and attention will be paid to the correct use of the significant figures. The experiment approach that will be used will tell the mass and volume of the metal and liquid determined by measuring these two quantities with a graduated cylinder and biuret. Procedure: a) The density of metals

Cola Explosion When the Mentos come into contact with the Diet Coke‚ a reaction causes the rapid formation of foam. it is concluded that the potassium benzoate‚ aspartame‚ and CO2 gas contained in the Diet Coke‚ in combination with the gelatin and gum arabic ingredients of the Mentos‚ all contribute to the formation of the foam. The structure of the Mentos is the most significant cause of the eruption due to nucleation.MythBusters reported that when fruit-flavored Mentos with a smooth waxy coating
