Water is essential for life and good health. It transports nutrients, aids digestion and metabolism, and removes waste from the body. Most health officials recommend drinking at least 8 glasses of clean water per day. Water can also aid in weight loss by suppressing appetite and helping the body burn stored fat. However, much of the Earth's water is contaminated, so point-of-use water treatment systems are necessary to provide clean drinking water.
The document discusses the transport of various substances in blood and compares the thermal properties of methane and water. It states that the mode of transport in blood depends on a substance's solubility. Glucose and sodium chloride dissolve in plasma due to their polarity, while cholesterol, fats, and oxygen require carrier molecules like lipoproteins and hemoglobin since they are non-polar and insoluble in water. Methane and water have similar molecular masses but different thermal properties due to hydrogen bonding in water. As a result, more energy is required to change water's state and it can absorb more heat than methane.
The document discusses the unique properties of water that make it essential for life. It explains that water's molecular structure causes it to be polar, allowing it to be an excellent solvent and giving it high surface tension, specific heat, and heat of vaporization. These properties, including its unusual density maximum as a liquid, are what allow water to exist as a liquid at Earth's surface temperatures and support all known lifeforms, which mostly contain water. The document emphasizes how water's intermolecular forces endow it with properties that no other substance has, making life as we know it impossible without water.
Plants use the process of photosynthesis to produce food. Photosynthesis requires light energy, carbon dioxide, and water. Chlorophyll in plant leaves traps light energy which is used to split water molecules, producing oxygen and sugar or glucose as food for the plant. Photosynthesis is important as it provides food for other living things, removes carbon dioxide from the air, and produces the oxygen needed for most organisms to survive.

Water has a unique structure and properties that make it essential for life. It is made of two hydrogen atoms bonded to one oxygen atom at a 104.5 degree angle. Water is polar due to this asymmetrical structure. It has many important properties including being a universal solvent, having a high heat capacity and heat of vaporization, strong cohesive and adhesive forces, and the ability to exist as both a liquid and solid at temperatures found on Earth. These properties allow water to moderate temperatures, carry nutrients in organisms, and change states of matter at temperatures habitable for life.
The document discusses water and its uses in food. It defines water as H2O, describing its unique properties including existing in three states, hydrogen bonding, and role in biological processes. Water exists in foods in free, absorbed, and bound forms, with bound water inversely related to water activity (Aw). Aw measures available water and is important for microbial growth. The document outlines water's various uses in food production from farming to processing. Overall, water plays critical roles in food textures, reactions, and microbial support.
Turbidity refers to the cloudiness of water caused by suspended solids. It can be increased by erosion, urban and agricultural runoff, sediment mixing from water bottoms, and algal overgrowth from farm runoff. pH measures acidity in water and can change due to acid rain, stormwater, and agricultural runoff. Dissolved oxygen in water is important for fish and comes from water movement and photosynthesis but can decrease due to thermal pollution and eutrophication. The biotic index uses the types of organisms in water to measure quality, with more species indicating better quality. Biological oxygen demand measures how much oxygen bacteria need to break down organic pollutants in water.
1. Matter is anything that has mass and takes up space, and can exist as a solid, liquid, or gas. It can change forms through physical or chemical changes.
2. Physical changes alter the shape or state of matter but do not change its chemical composition. They include changes of state between solids, liquids and gases caused by temperature changes.
3. Chemical changes alter the chemical composition of matter and create new substances. They include combustion, oxidation, and fermentation and are not reversible.
Plants use photosynthesis to convert sunlight, carbon dioxide and water into glucose and oxygen. During photosynthesis, chloroplasts in plant leaves use energy from sunlight to turn carbon dioxide and water into oxygen and glucose, storing the sun's energy in the chemical bonds of glucose. Plants then use respiration to break down glucose and release energy, using it to grow.
