a substance (Moore‚ Stanitski & Jurs‚ 2009). Freezing point is the fixed temperature at which a pure liquid converted into crystalline solid. Melting point is the fixed temperature at which a crystalline solid converted to a liquid (Ebbing & Gammon‚ 2010). The melting point of a solid and the freezing point of its liquid is the same. It is the temperature at which the rate of freezing of its liquid is the same as the rate of melting of a solid under a given applied pressure (Whitten‚ Davis & Peck

Relating Mass and Volume Question: What does mass have to do with the amount of space (volume) a liquid occupies? Hypothesis: I believe that the mass and volume is related because they both rely on each other for their purpose. If we fill the cylinder to a certain measurement (volume)‚ then the mass will grow with it. There is a balance. Materials: - Distilled water - Corn syrup - Saturated solution of salt water - Triple beam balance - 150 mL (or larger - Small plastic pipette - 150 mL beaker

INTRODUCTION Colligative properties In liquid solutions‚ particles are close together and the solute molecules or ions disrupt intermolecular forces between the solvent molecules‚ causing changes in those properties of the solvent that depend in intermolecular attraction. For example‚ the freezing

in solids‚ liquids‚ gases‚ and plasmas. You can determine whether an object is a solid or not based on two characteristics. Solids have a definite shape and a definite volume. Solid’s particles are so close together that they cant move and that’s what keeps a solid a definite shape. Little motion can occur in the particle arrangement. Particles in liquids‚ however‚ can move more freely. The particles are close together but are not as tightly packed as solids are. Like solids‚ liquids have no definite

emulsion‚ which is a mixture of two liquids that normally cannot be combined. Mayonnaise is made by combining lemon juice or vinegar with egg yolks. The egg yolk is obtained and10 drops of was added to the egg yolk in a beaker. Oil was then added in a steady stream while whisking. This was done until the oil was completely mixed in and the mayonnaise was thick and fluffy. There was an emulsion created; a dispersion of one liquid (the oil)‚ inside another liquid (the vinegar)‚ with an emulsifier (the

a body in a liquid than in the air? ~ We know that‚ Upthrust =Density of fluid*acceleration due to gravity*Immersed volume of the body From the realtion above‚ it is clear that upthrust given by a fluid to a body is directly proportional to the density of the fluid. Also‚ as a matter of fact‚ the density of air is less than that of liquid. So‚ the liquid provides greater amount of upthrust than the air does. This implies that a body loses its weight greater in air than in the liquid. Therefore

I LIQUID STATE ii GASES STATE In solid molecules are very closed spaced where as liquids. The spacing b/w the different molecules is relatively large and in gases the spacing b/w molecules is still large Its means the intermolecular cohesive forces are large in solids‚ smaller in gases and extremely small in gases and on account of this fact solids posses compact and regional form‚ liquids molecules

jar in a sunny spot.) Strain the mixture through a coffee filter or paper towel. Leave the strained alcohol in a small covered dish. When the alcohol evaporates‚ the remaining liquid is the orange oil. Mix the orange oil with the Styrofoam. The Styrofoam will then break down into a thin liquid form. Take the resulting liquid‚ which will amount to an orange scented glue and pour into a jar. Label it well as "Glue" before you put it away‚ so you and your household will know what it is later. D.
