was calculated to be 45.76g. The error of the carried out experiment was calculated to be 20.06%. Introduction: A substance requires energy to change from one phase state to another‚ or in other words‚ when it goes from either a solid to liquid or liquid to gas. The potential energy that is stored between molecules of the substance needs to be overcome by the kinetic energy of the motion of the particles before the substance can undergo the phase change. The temperature of a substance as heat

DENSITY OF LIQUIDS AND SOLIDS by Lab instructor: Due date: Results and discussion: The purpose of the experiment was to determine the densities of the unknown liquid and solid as precisely and accurately as possible in order to identify them. It was carried out first on distilled water in order to rule out systematic errors. A 10 mL beaker was placed on a top pan balance and “tared”. The beaker was then removed and 10 mL of distilled water was pipetted into it before it was placed

In the novel Catalyst by Laurie Halse Anderson‚ there are three main sections‚ Solid‚ Liquid‚ and Gas. The main character‚ Kate‚ is very interested in science and the three titles are a metaphor for her state of mind throughout the book. The first section‚ Solid‚ shows how Kate is a stable and strong person. The next section‚ Liquid‚ is a time where Kate’s life is very inconsistent and she is unsure about herself. The last section‚ Gas‚ shows how Kate has accepted her fate and tries to help everyone

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

to absorb liquids. It doesn’t matter if the sponge is from the sea‚ or from a factory‚ they both use wicking and surface tension in order to absorb sponges. This use is what allowed the sponge to soak its way into history. Sponge absorption is the key power that utilizes wicking and surface tension to soak up liquids. Wicking‚ or capillary action‚ allows water to be stored in sponges when they soak up liquids. According to World Book Student‚ capillary action is the movement of liquid in tiny holes

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.
