Introduction

Heat travels in three forms; conduction, convection and radiation. In this experiment the process of convection and radiation was investigated. Convection occurs due to the fact that when a gas is heated its pressure will remain the same and its density drops. Therefore, in a system the warmest gas will always travel to the “top” of the system where density is at its lowest.

Heat travels through this form by creating a cycle of cold air replacing the risen warm air. The cold …show more content…

  • Cold Pack And Exothermic Reaction Lab Report

    722 Words  | 3 Pages

    Chemical bonding, also known as chemical reactions, are happening all around us. From cold packs we use on various injuries to the water we drink, they’re all results of chemical bonding. To be more specific, endothermic and exothermic reactions are both types of chemical reactions that are classified by the heat energy that is either released or absorbed when a reaction occurs. An example of an endothermic reaction would be an “instant cold pack”, which become chilled when activated. As for exothermic reactions, “hot packs” make great examples due to their significant temperature increase in just a few minutes.

    The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

    When the material heats up it rises and when it cools it sinks it is a repeating cycle. The hot water was less dense causing it to rise and it is less dense because the particles are beginning to spread out and not be close any longer. The cold water sinks because it’s more dense because the particles become close together and compacted they don’t move as much. Since the cold is more dense it

    As mentioned in the hypothesis, the prediction is that as the temperature increases towards the optimal, the rate of respiration will increase. As the temperature exceeds the optimal, the rate of respiration will decrease. The temperature of the environment can be varied by placing the respiration chamber under a temperature-controlled water bath/cooling bath. The temperatures that will be used in this experiment will range from 0ºC to 50ºC in 10ºC increments. Digital thermometer will be used to measure the temperature of air.

    Data Analysis It was evident throughout the experiment that in the compound the metal determined the color of the flame. The color depended only on the metal component of the compound. The non-metal element that was in the compound did not mater. Compounds with Lithium (Li) were always red, compounds with Sodium (Na) were always yellow, compounds with Calcium (Ca) were always orange, Compounds with potassium (K) were always lilac, and compounds with Copper (Cu) were green.

    Our objective was to pick the best chemical to be used in a hand warm. This chemical had to be cheap, relatively safe, and must raise the temperature by 20oC and no more. We add 6 different chemicals to water we record the inshell temperature and then add one a the 6 chemicals to the water and record the temperature change of the water. We also add cold water hot water together to find how much heat would escape the calorimeter. We found that the calorimeter absorbed 71.1J/oC. Then this information to calculate the energy that was released by all of the chemical reaction.

An example of a organism who has multicellular cells are plants, animals, and humans. The main reason of why scientists have a hard time finding a good set of existing organisms to compare. Is neither the first set of organisms which is being compared is dying as fast as the second specimen is being examined or they just can’t find the right species.

This lab was made with the aim of proof that making different activities can alternate the ventilation rate, also is to see the variation of work our respiration system makes. We can see the different things and situations that can affect the normal process of ventilation and respiration, like the weather and the clothes that were limitations for doing this experiment because first the weather was so hot, so the person get tired early and began to ventilate faster and second the clothes wasn't appropriate for making the activities, because they also make weight and makes that the person get more tired. We use more than one person to make a comparison of the ventilation

    Properties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has

  • Heat Stress Research Paper

    Heat stress is a condition in which the increase in core body temperature overwhelms the body’s homeostatic thermoregulation abilities, thus producing and absorbing more heat than the body could dissipate [1]. This results in a wide spectrum of heat-related illnesses, ranging from minor conditions such as heat cramps and heat exhaustion to the more severe condition known as heat stroke. Heat stroke is defined as a core body temperature of beyond 40.60C, commonly associated with the dysfunction of the Central Nervous System (CNS) and the failure of multiple organ systems, which may ultimately result in disability or death. [2] Heat stress can be categorized into two different entities: classical and exertional. Classical or environmental heat

Over the past month or so I, Dylan Garofalo, have been researching anything and everything that has to do with an instrument and how it works. The subjects that are connecting to my problem are such things as vibration, sound waves, frequency, and how all of these subjects connect to create the sound that is emitted from mostly any instrument. To find the intriguing answer to my problem statement I will use a device known as an oscilloscope to find out how large or how small of a sound wave is emitted from each instrument that I have availability over.
