How Does Water's Higher Specific Heat Capacity Aid Our Lives

water is used to cool the body. One point was earned for explaining that water stabilizes temperature

What special bond (in water) opposes water’s molecular movement when water absorbs energy requiring water to have more heat added to raise its temperature? Hydrogen Bond.

Overall, we were able to discern that calcium chloride would serve as the most effective ionic solid within a hand warmer. Foremost, it served as one of the most effective solids in regards to heat production. The reason being, as seen from our calculations, when one places 10 grams of any of the ionic solids tested in the experiment inside a hand warmer containing an inner pouch of 40 mL of water, calcium chloride has the second greatest expected increase in regards to the heat of the solution. Also, these two compounds have the greatest heat of solution of all the tested ionic compounds. The only ionic solid which trumps calcium chloride in this category, would be lithium chloride. However, due to lithium chloride greater toxicity in comparison to calcium chloride, one will have to deem the latter as our most effective hand warmer. This can be seen as skin must be immediately washed with water when it comes into contact with lithium chloride, such measures are not necessary with the slightly hazardous calcium chloride. Additionally, lithium chloride has the greater personal protection rating in comparison to that of calcium chloride from their respective MSDS sheets, with a rating of E to C. Thus, the former requires a greater degree of protection on the part of the users to prevent harm. Since hand warmers will come into contact with the hands of users, and there is a potential of a leak, calcium chloride is the safest option, as even in the case of a leak, the safety of

The bond between the compounds and the water molecules is weak and therefore easily broken. Typically, these bonds are broken through the heating of the compound.

(Click Slide) Another unique property of water is its high specific heat capacity. Due to the strong hydrogen bonds that exist between water molecules, a lot of energy is needed to break down the bonds. As the Particle Theory states, particles move faster and further apart when heated. This is why water helps maintains a moderate temperature on Earth and different bodies of water, crucial for the survival of organisms.

Homeostasis is described as the body's ability to maintain internally stable conditions. Each organ plays a huge role in maintaining this stability.

Added temperature furthermore drops the quantity of oxygen molecules, which is dissolved in the water. Water composed of two negatively charged oxygen atoms and one positively charged hydrogen. When the temperature is cooler these particles encompass less energy and there is less change that they get separated from each other. In contrast atomic particles are more energetic when the temperature is warmer ands so they will get separated from the hydrogen atom. So cold water holds more oxygen (Mallya 2007). Added temperature furthermore drops the quantity of oxygen molecules, which is dissolved in the water.

energy than it does to turn water into ice. The extra energy that is used in

Intermolecular forces hold molecules together when they are in solid or liquid state. However, water has the ability to dissociate many salts and ionic compounds. This is called dissolving. When NaCl is added to water, it dissociates into the ions; Na+ and Cl- . The positive sodium ions are surrounded by the slightly negatively charged part of water molecules (i.e. oxygen) in the water molecules and the negative chlorine ions are surrounded by the slightly positively charged part of water molecules (i.e. the hydrogen). The kinetic energy of the sodium chloride molecules increase with temperature. This destabilizes the solid state that it is currently in. This increased motion means that the molecules are less able to hold together and as such they dissolve at faster rates and larger amounts.

Water has a high specific heat capacity compared with other liquids. This means that a large increase in energy results in a comparatively small rise in the temperature of the water. This is because much of the heat absorbed is used to break the hydrogen bonds that hold the molecules together. Water is good at maintaining its temperature at a steady level, irrespective of fluctuations in the temperature of the surrounding environment. This is important because the range of temperatures in which

retain heat and can be seen to be used in the example of Emperor penguins in the icy Antarctic.

This experiment was dealing with the heating of water with different types and sizes of metals. In it you had to deal with heat capacity. Heat capacity is the amount of heat (normally expressed in calories, kilocalories, or joules) to raise a substances temperature by one (1) degree (normally expressed in Celsius or Kelvin). With the answer expressed in units of thermal energy per degree temperature. With substances having certain specific dimensions you can use to types of heat capacity, Molar Heat Capacity and Specific Heat Capacity.

For hot and cold, if the temperature is hot our body is releasing sweat which gives us cooling effect. The blood vessels in the skin becomes broader to increase the blood flow in our skin and

This capability offers a smooth draw despite the amount of smoke inhaled. Warm water kills any bacteria available in the smoke, providing a cleaner inhalation. This can minimize exposure to most common smoking-related conditions like bronchitis, if used in moderation.

Sweat glands play an extreme part in temperature control. For example, the perspiration of a hippopotamus does more than just keeping the animal cool. “A secretion of the hippopotamus protects the animal’s skin from the sun and bacteria thanks to two pigments
