Bill Giordano Chemistry Mrs.Rupinski 5/5/10 Specific Heat Although specific heat measures joules, specific heat needs the capacity, the mass, and the final change in temperature to figure out exactly what the specific is. Specific heat is measured in joules, measures the amount of heat ones temperature can hold. Specific heat’s unit is J/g*C. That unit stands for joules over grams per Celsius. For example copper’s specific heat is 0.385 J/g*C. If you we’re to solve an equation involving specific heat the formula is Q = (Cp) (M) (T). Whereas Cp stands for specific heat, M stands for mass and T stands for change in temperature. The triangle stands for delta as the Greeks had named it long ago. Specific heat is basically heat energy that gets stored in places outdoors or indoors. A copper plate on the bottom of pot on a stove over a flame stores more specific heat than some other elements and metals because H2O particles and atoms are released quicker when heated to create a hotter specific heat. Specific heat’s greatest partner in role is water. Water is called the universal solvent because it can dissolve so many elements, compounds, and solutions. Water is made up of 70% of the Earth and is in more than 2/3 of the human body. Water is the simplest liquid to be used in specific heat. Water has a high specific heat because hydrogen bonds between the water molecules are weak and temporary. Molecules are constantly breaking apart it takes more energy to heat up water rather than a solid. To find the specific heat of a substance, determine the specific heat capacity of a substance. First drop a substance into a heated container of liquid. Find the mass of the substance then, find the initial and final temperature of the substance. The greater the specific heat capacity of a substance, the more thermal energy is required to increase the temperature of that substance by 1o Celsius. As liquid crystals and H2O undergo a change, specific heat is to understand the change in variations. Although there are several causes that change specific heat, one of them is temperature. Temperature measures the average kinetic energy in a substance or an object. A substance needs to store kinetic energy in order to have internal motion. The results of the inertia of the reactions are referred to internal degrees. Internal degrees must have freedom, meaning its atoms are able to move about. Smaller molecules of substances have less freedom, in which they have less heat capacity. Larger molecules of substances have more freedom, in which they have more heat capacity to maintain. Resulting in this, gaining more heat means more kinetic energy and all the atoms will be rushing all over the place. Humans use specific heat in their everyday use. Even when people don’t even know, specific heat is being used every single second around the world. Not only do people use specific heat, but the sun uses it constantly. The sun heats the air, land, and oceans during the day. At night the land and air cools due to lack of sun, meanwhile the ocean absorbed so much energy that it remains warmer near sundown. An example of specific heat is ironing. An ironer uses specific heat to heat up water which turns into steam, to straighten out clothes.
