High Specific Heat and Heat of Vaporization of Water in Comparison to Isopropyl AlcoholBrandon BagoyoMarine Science Period 1September 18th, 2018INTRODUCTION
Ah, water. Something that may seem so little & insignificant, yet it is responsible forproviding life for many species on planet Earth.Heat capacitycan be defined as the amount ofheat needed to raise the temperature of something by one degree, typically expressed in thetemperature units -- Celsius or Kelvin. We truly do take the properties of water for granted.When compared with isopropyl alcohol and various other liquids, water possesses a heatcapacity of1.00 calories per gram of celsius.Isopropyl alcohol on the other hand has a heatcapacity of0.62 calories per gram of celsius. In simpler words, water takes a longer to heatup, to a boiling point per se, when heated simultaneously alongside a beaker of isopropylalcohol. Moreso evidently, isopropyl alcohol has a lower capacity of heat and less energy for itto get hotter than water, due to water’s greaterdensity. The reason why water’s high heatcapacity is AND should be important to us is because it regulates the heat given off from thesun. Being that water is capable of absorbing the heat we feel walking down the street on a hotsummer day, it sustains not only life on Earth, but performs well in a car’s radiator coolant! Thisis due yet again to its heat absorption ability to keep drastic changes in temperature to aminimum. Is there anything really that water can’t do?! The next time you’re boiling a pot ofwater for pasta, don’t yell at it because it’s taking so long! Be appreciative of water more.On the same matter, theheat of vaporizationis defined simply as theenergy requiredto transform a given quantity of a substance from a liquid into a gas. Again we compare the two-- water and isopropyl alcohol. With previous known information, we see that water maintains aspecific heat of vaporization quantity of2260 Joules per gramin contrast to the isopropylalcohol quantity of732 Joules per gram. Significantly, you may notice that water requires muchmuch more energy to reach its boiling point and convert into its gaseous form. Thus it is
