Specific Heat Capacity Laboratory Report

The study of science is Physics. Physics means the natural science which involves the study of things made up atoms or matter, and along with related concepts such as energy and force. The experiment is Physics because we are using heat from the sun, and transferring the heat to the oven. So heat or thermal energy is the measure of the amount of energy that is contained in a material. Heat depends on how much of the material, which would be sunlight, you have: if you have twice the amount then normal of whatever you are testing, then you have to double the amount of heat you have. “Temperature is a measure of the ability of a substance, or more generally of any living or nonliving subject, to move the energy made of heat to another living or nonliving subject.” “But we need to remember that light slows down has it goes farther from the sun, and bends toward the normal and has a shorter wavelength when it enters a higher value medium (A substance that makes it possible for the energy to move to one location to another)”. “ Also a light wave is transverse (they can be polarized).”

In this experiment, the results of the tested materials gave off heat and the change in the temperature was positive because when one substance was added to another the temperature increased. A calorimetric constant is required because the calorimeter that was made is different for every lab group.

Calorimetry is the science of measuring the change in heat absorbed or released during a chemical reaction. The change in heat can tell us if the reaction is either exothermic - it released or heat into surroundings, or endothermic - it absorbed heat from surroundings. The device used to measure calorimetry is a calorimeter. A calorimeter can range from very expensive lab ones to coffee styrofoam cups but they are all tightly sealed in order to prevent heat from escaping.

Heat: The amount of energy associated with the movement of atoms and molecules in matter.

Heat is a form of energy, sometimes called thermal energy, which can pass spontaneously from an object at a high temperature to an object at a lower temperature. If the two objects are in contact, they will, given sufficient time, both reach the same temperature. Heat always travels from hot to cold objects and two objects will reach an equilibrium temperature. Heat flow is commonly measured in a device called a calorimeter, an insulating container that minimizes heat exchange between its contents and the surrounding. Heat flow in a device called a calorimeter. In this experiment, we should find the heat capacity of the

The heat capacity per unit mass of a body, called specific heat capacity or more simply specific heat, is used to more directly compare the heat capacity of substances. Pure water has high specific heat capacity that is exactly 1 calorie per gram, whereas other common substances have much lower specific heats. The reason is because it takes more energy to increase the kinetic energy of hydrogen-bonded water molecules than it does for substances in which the dominant intermolecular interaction is the much weaker van der Waals force. As a result, water gains or loses much more heat than other common substances while undergoing an equal temperature change.

The lab used methods of calorimetry in order to measure the temperature change of reactions and calculate the changes in

There are four basic components for thermal energy (heat): 1. All matter is made up of tiny particles called atoms. These can only be seen with special microscopes. 2. The atoms are always moving – they all have kinetic energy. 3. The particles have space between them. Different states of matter have different amounts of space. 4. Adding heat (energy) to matter makes the particles move more quickly. Since faster moving things have more kinetic energy, adding heat increases the energy of the particle. 5. Cooling it down decreases the amount of kinetic energy and slows the movement down.

Procedures: We set up an appropriate apparatus including a Styrofoam calorimeter cup containing room temperature deionized water, two thermometers, and a clean beaker also containing deionized water directly on a heat source. After heating up the water until its boiling point, we recorded the mass of each metal and carefully placed the selected metal inside the boiling water until the temperature of the water containing the metal was constant. Quickly, we placed the hot metal from the boiling water in the calorimeter cup containing room temperature water

Substances differs from each other as each of the substances have different atomic composition and structures. And although the substances that shares the same characteristic can be grouped together, each of the substances still have their own unique and defining physical and chemical properties. Therefore, some substances may undergo a chemical change while others don’t during a same reaction. In the experiment conducted, two different elements were used, Iodine crystals, I2 and Copper wire, Cu. After recording the initial observation on both of the elements, they were both heated and allowed to cool.

Temperature is a measure of the average kinetic energy of the particles in a body. Temperature can be understood by recognizing that a hot object contains more thermal energy than a cold object. The amount of thermal energy in a substance is affected by the amount of particles that are in it. Temperature is independent of number of particles in

Heat is a form of energy that is transferred between two substances at different temperatures. The flow of the energy is from the object of higher temperature to the object of lower temperature. The heat is measured in units of energy, usually calories or joules. Temperature on the other hand, is how cold or hot an object is. The temperature is the average kinetic energy per molecule of a substance. This is measured in degrees on the Celsius or Fahrenheit or in Kelvins.

Purpose: To measure the heats of reaction for three related exothermic reactions and to verify Hess’s Law of Heat Summation.

Overall, the experiment succeeded that the metals show the theoretical properties. Differences existed in the mathematical calculation of the actual length. These differences, however, it can be accounted for by experimental error; more over there are uncertainty on purity of the
