Cognitive Properties Ashley Weber Principles of Chemistry 2 Experiment 1 02/02/2015 Abstract: Several experiments were performed to observe the colligative properties. This includes the freezing point depression‚ and osmotic pressure. Two ice baths were made‚ one with pure water‚ the other with salt water. The lowest temperature was then record for each bath and compared. The salt water had a lower freezing point than the pure water by 2 degrees which supports the hypothesis that solutions have

Continue of Properties of Life: in sexual reproduction‚ two parents contribute genetic information in the form of a gamete. The gametes fuse and an offspring is produced from the fertilized egg. The fourth property of all living organisms possess is that populations of organisms evolve over many generations. Adaptations are inherited characteristics that allow organisms to survive in a particular environment. The seahorse has evolved and adapted camouflage. Which property is NOT a property of all

The purpose of this experiment is to discover the physical and chemical properties of the studied gases. In discovering these properties it allows the student or observer the ability to identify these gases when they come into contact with them. Procedure Before I began the procedure I gathered all my supplies from the given list in the manual. From there I began the actual experiment and diluted the HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper

Danielle Silverstein PHY 101 Section 10497 March 4‚ 2013 Light up this World Purpose: In this lab experiment‚ LED lights will be used to show how when E&M radiation is absorbed‚ the energy is converted to heat. A drop of isopropyl alcohol will absorb light energy of different colors‚ and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs

Properties of Water Water is essential for life as we know it on earth. It is used by plants and animals for basic biological processes which would be impossible without the use of water. The origin of all life can be traced back to the water in the Earth’s precambrien seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted
