Paraskevi Campus we deal with the density of solids and density of liquids. The main purpose of this experiment is to understand what in reality density means‚ how we can measure it‚ how useful it is‚ what is the difference between density of solids and liquids‚ if the measurements that we did are been accurate and how we can calculate the percentage errors. materials 3 different metals A) copper B) iron C) aluminum - 3 Different liquids A) Water B) Olive oil C) Alcohol

a NICOLET iS5 FT infrared spectrometer. The IR sample of a liquid is obtained on a pure liquid called a neat sample whereas solid sample was obtained with the help of an Attenuated total reflectance IR spectra. The index of hydrogen deficiency determines the saturation of a compound (double bonds‚ triple bonds or rings). Elemental analysis helps in determining the molecular formula of a compound. The boiling point of an unknown liquid sample was determined with a mini scale technique. It consists

Water (Syllabus Topic 8.4) Our planet is rich in water‚ in solid‚ liquid and gaseous forms. Water is essential for the evolution of life and the continued existence of life on Earth. Complete the following revision passage using these words: solution‚ spheres‚ dense‚ solid‚ solute‚ biosphere‚ dissolves‚ gas‚ mass‚ volume‚ solution‚ lithosphere‚ liquid‚ solid‚ gas‚ state Water is a very useful solvent. A solvent is a substance which ____________ other substances. A substance which gets dissolved

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

table represent the same thing‚ the temperature of the solution during fractional distillation. At the start of the fractional distillation‚ before we started the fire‚ it was 25° celcius. At the end of the fractional distillation‚ when all of the liquid was gone‚ it was 99.3 degrees. This set of data is not the first time we did the fractional distillation‚ it’s actually probably the 3rd or 4th. The first time we didn’t actually record the temperature‚ we just looked for the plateaus‚ we found them

Matter In Our Sourroundings Important Questions Not for coping to note Q. 1. What is a matter? Answer : Anything that occupies space and has mass is called a matter. For example:- Chalk‚ Milk‚ Sugar etc. Q. 2. Sodium chloride and sugar have same appearance. Are they same or different? Answer : They have different physical and chemical properties. So‚ they are different. Q. 3. All substances around us are alike. How? Answer : All substances can occupy space and have weight.

were to determine the densities of some solids and liquids and to apply the rules of significant figures in computing laboratory data. For liquids‚ a dry‚ empty 100-ml graduated was weighed. Fifty ml of water was placed in it‚ then weighed again. The same was done for other liquid samples. The mass of the liquid sample was determined by subtracting the mass of the empty graduated cylinder with the mass of the cylinder and liquid. For the density of solids‚ the rectangular block was weighed and

Filtration is a process where solids and liquids can be separated. The liquid that passes through the filter paper is called a filtrate. Evaporation is a process where two liquids or a solid mixed into a liquid can be separated. To separate two liquids mixed together‚ the liquid
Premium Mixture Separation process Water
Filtration Filtration is a mechanical or physical process to separate solid particulates from fluids Filtration is a technique used to separate a solid from a liquid. The solid is separated from the liquid phase by passing the mixture over a filtering media. Filtering media is characterized by being chemically inert to the mixture‚ and having small pathways for the liquid to pass through‚ but these pathways should be smaller than the solid particle size. Filtering media can be prepared using paper‚ fritted-glass
