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

UNIVERSITY OF WISCONSIN / INDUSTRIAL REFRIGERATION CONSORTIUM J. MICHAEL FISHER VILTER MANUFACTURING CORPORATION Executive Summary The objective of this paper is to review the literature on the principles governing gravitydriven separation of liquid-vapor mixtures‚ review design methods for separators‚ and develop a model that predicts separator performance given operating requirements (i.e. size or velocity‚ and design droplet size) subject to design constraints. The model presented can serve

The object of the lab conducted was to find the density of the substances given and to find what the unknown liquid and solid were. The process to finding what the unknown solid and liquid were‚ was to find the density and to conduct multiple trials so when the density is discovered‚ it is possible to compare the density found to another one in order to find the liquid or solid. Through finding the density of objects and substances‚ it is possible to find what the subject is that

Vaporization Introduction: Evaporation is the process of a liquid becoming vaporized. When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid‚ new gas molecules exerts pressure in the sealed container‚ while some of the gas condenses back to the liquid state. If the temperature inside the container is kept constant

solution C ABSTRACT Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119.0C while the boiling point of liquid C was found to be 117C

rubbing alcohol and hand soap. A pipette was used to place consistent drops of liquid into a 10 ml graduated cylinder until it was filled to the 10 ml mark. The level was measured at the meniscus‚ bottom of the curve‚ of the liquid and the amount of drops was recorded. Dividing the volume (10 ml) by the amount of drops yields the volume of a single drop. This procedure was completed three times with three separate liquids; water‚ water with detergent and rubbing alcohol. Data from the three trials

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

Comment on the accuracy of the statement below. Describe some exceptions to the statement if there are any. In general‚ solids are denser than liquids‚ and liquids are denser than gases. 5. Use the particle theory to explain why changing the temperature of a fluid can also change its density. 6. The density of a fluid
