The capability for a molecule to absorb heat energy is called heat capacity, which can be calculated by the equation shown in the figure. Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy. Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius. For water, this amount is one calorie, or 4.184 Joules. As a result, it takes water a long time to heat and a long time to cool. In fact, the specific heat capacity of water is about five times more than that of sand. This explains why the land cools faster than the sea. C=QΔT.C=QΔT. The resistance to sudden temperature changes makes water an excellent habitat, allowing organisms to survive without experiencing wide temperature fluctuation. Furthermore, because many organisms are mainly composed of water, the property of high heat capacity allows highly regulated internal body temperatures. For example, the temperature of your body does not drastically drop to the same temperature as the outside temperature while you are skiing or playing in the snow. Due to its high heat capacity, water is used by warm blooded animals to more evenly disperse heat in their bodies; it acts in a similar manner to a car’s cooling system, transporting heat from warm places to cool places, causing the body to maintain a more even temperature.
Finally the high specific heat of water makes it resistant to temperature change allowing life forms to maintain relatively constant internal temperatures. The high specific heat and surface tension of water contribute to its high boiling point helping to keep it in liquid form for most biological processes. How does water’s specific heat relate to its usefulness for life give examples?Water’s high specific heat is very useful to life.

Why is it important that water has a high specific heat quizlet?The high specific heat of water helps to 1) moderate temperature in coastal areas 2) stabilize ocean temperatures creating a favorable environment for marine life 3) because it covers most of the earth it keeps temperature fluctuations within the limits for life 4) helps organisms (that are made primarily out of … Which is a result of water’s high specific heat?Because of its high heat capacity water can minimize changes in temperature. For instance the specific heat capacity of water is about five times greater than that of sand. The land cools faster than the sea once the sun goes down and the slow-cooling water can release heat to nearby land during the night. What are the three uses of specific heat of water in daily life?Explanation: Fomentation: Hot water bottles are used for fomentation as the water remains hot in the bottle for a long time in spite of giving off large quantities of heat. Car radiators: Water is used as coolant car radiators. Bottled Wines: In cold countries wine bottles re kept under water. Why is high specific heat capacity important to life?The high specific heat of water means that it requires a large amount of heat to raise the temperature of water. This helps the temperature of the environment from becoming too hot or too cold. Also humans are about 66% water thus this property of water helps us regulate our body temperature too. What are the specific uses of heat in industry and into your daily life?
The heat is very important in our daily life in warming the house cooking heating the water and drying the washed clothes. The heat has many usages in the industry as making and processing the food and manufacture of the glass the paper the textile ………etc. What statement explains the relationship between the water and the metal you are studying?What statement explains the relationship between the water and the metal you are studying? The heat lost by the metal is equal to the heat gained by the water. What are the two common values used as the specific heat of water?
Heat Capacity and Specific Heat
The SI unit of specific heat capacity is joule per kelvin per kilogram J⋅kg−1⋅K−1. For example the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1. What was the effect of increasing the water’s mass?Analyze: For each factor listed in the chart below explain how the final temperature was changed and why you think that change occurred. A. What was the effect of increasing the water’s mass? Increasing mass will increase the substance’s heat but won’t affect its temperature since they are not reated. Is water essential for life?Water. … Liquid water is an essential requirement for life on Earth because it functions as a solvent. It is capable of dissolving substances and enabling key chemical reactions in animal plant and microbial cells. Its chemical and physical properties allow it to dissolve more substances than most other liquids. Why is the density of water so important to life on Earth?Water is less dense as a solid than as a liquid. This property is important as it keeps ponds lakes and oceans from freezing solid and allows life to continue to thrive under the icy surface. How does the specific heat capacity of water affect people’s homeostasis?High specific heat is waters ability to slowly heat up and cool down. This allows water to help maintain homeostasis in the human body. The heat stored in water is moving to the surface evaporating while taking heat with it. What are some examples of water being used as a solvent to support life?That water serves as the solvent for sodium chloride (salt) and other substances so that the fluids of our bodies are similar to sea water. This leads Hill and Kolb to refer jokingly to us as “walking bags of sea water”. Water serves to suspend the red blood cells to carry oxygen to the cells. How do water’s hydrogen bonds contribute to cohesion?This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other.
