Date: ____________ Properties of Water Lab Introduction: Water is a simple molecule‚ yet itʼs most vital to all living things. It has the highest specific heat of everyday substances. Unique properties of water enable it to carry out functions that no other substances can. In a neutral aqueous solution‚ five molecules of water are bonded together by weak hydrogen bonds. Furthermore‚ due to the electronegativity of oxygen‚ water is a polar molecule. Due to its polarity‚ water is classified as the

Design Experiment to investigate the effect of the concentration of Sodium Hydrogen Carbonate on the rate of photosynthesis using Cobomba plant. Aim: The aim of the experiment is to investigate the effect of the concentration of Sodium Hydrogen Carbonate (NaHCO3) on the rate of photosynthesis using a Cobomba plant. Hypothesis: As the concentration of NaHCO3 increases the rate of photosynthesis of the Cobomba plant should increase‚ as there is a greater presence of a carbon dioxide‚ obtained

specific heat is one of five properties of water that is important to life. Specific heat is defined as the heat necessary to raise one gram of water by one degree Celsius. Because water’s temperature does not change dramatically when absorbing or losing heat‚ water can absorb or release exceeding amounts of heat (by breaking and forming hydrogen bonds) without affecting living organisms in the water and at the same time helping terrestrial organisms outside the water live easier. For example‚ coastal

Water is the most abundant molecule on Earth’s surface. It is essential for life on Earth. The unique properties of water makes life possible on earth. One property of water is surface tension. Water has a surface tension 2 – 4 times the surface tension of most organic liquids. Surface tension is highest for pure water. This enables insects called neuston to walk and live on the surface of water in low-nutrient water bodies‚ where they would starve if immersed in the water. This anomaly permits
