Charisse Brittney Ann Vicente __________________ THE SCIENTIFIC METHOD: IDENTIFYING WHICH LIQUID EVAPORATES FASTER I. Objectives To know the step-by-step procedure in conducting an experiment To determine how the process of scientific method helps us to solve a certain problem To identify which liquid evaporates faster. II. Science Concept Evaporation is the process whereby atoms or molecules in a liquid state gain sufficient energy to enter the gaseous state. The rate of evaporation is dependent

The objective of this lab was to. First‚ we measured out 2.00g of granular zinc and 2.03g of iodine crystals and added them together into a boiling tube‚ which we labeled "R". After‚ we added a boiling chip into a large test tube labeled "P" and we also labeled an empty regular sized test tube with a "C". When we added 5mL of acetic acid to tube R‚ the solution turned red and was hot. After we add 30 drops of the red solution into tube C and continued to swirl tube R‚ the solution became

The order that the liquids were in was blue‚ orange‚ green‚ yellow‚ and red. On our first trial‚ we only put in blue‚ green‚ red‚ and yellow mixtures inside the test tube. Before we even put in the orange solution‚ the yellow liquid started to mix in with the red solution. It meant that the yellow sugar water was more dense than the red sugar water. On our second trial‚ we tried to put the green mixture first to see what would happen. When we put the green mixture inside the test tube‚ we decided

In Crystal Eastman’s essay “Now we can begin” she gives her view of feminism during this time period and how it was viewed as negative since all the feminist leaders at the time was associated with socialism or communism. This negative social view prevented progressive movement in feminism. In “Now we can Begin” Crystal Eastman effectively uses examples on how the women’s right to vote in the 1920s would lead

Effects of different liquids on the elasticity of a rubber band Luke lash and Charles baker Question: If we submerge rubber bands in different liquid substances‚ will its elasticity of the rubber bands increase? Hypothesis: If we use a more acidic substance like vinegar‚ then elasticity of the rubber band will increase. Background: We are conducting this experiment because although it has been done before‚ the substances that have been used before are generally ordinary. Others have used hot

preparation and stability of liquid Paraffin Emulsion Abstract This study describes the preparation of a Liquid Paraffin Emulsion from Paraffin oil‚ Emulsifying agents and Distilled water. This report will also evaluate the stability of the Liquid Paraffin Emulsion depending on how the emulsion is produced and whether using different methods of mixing will produce a more stable Paraffin Emulsion. Introduction An emulsion is a mixture of two or more liquids that are normally not formed
