Heat Loss Investigation

Introduction

My investigation is to find out the rate of which heat is lost or

transferred. Heat loss happens when heat energy is exchanged between

materials that are both at a two different temperature. There are

different ways in which heat is lost they are: - conduction,

convection, radiation and evaporation. All these processes can happen

to heat.

How am I going to carry out the investigation?

I will be investigating the heat loss in animals and will be using

cans to discover which can looses the most temperature. To do this

experiment I will be using small, medium and large cans to perform as

small, medium and large animals. Water will be positioned in these

three different sized cans and the first measurement will be taken at

the same temperature to keep it a fair test. I will be taking about

eight readings at two minute intervals. Then I will repeat the

procedure, this will then make it possible for me to take the

averages.

The Equipment I will require.

* A small (150ml), medium (340ml) and a large can (520ml) - to

position the hot water and then be able to put the thermometer

into the cans to obtain the readings.

* Stopwatch- needed to keep track of the time and to make sure the

reading is taken at the right time.

* Measuring Cylinder- to measure the amount of water placed into the

cans.

* A kettle- used to produce hot water.

[IMAGE]

* Thermometer- to measure the temperature of the water.

How will I make it a safe investigation?

To make it a safe investigation I will need to put on goggles to

shield my eyes from the sweltering water. Gloves will also be worn to

guard my hand from the

    First, 100 mL of regular deionized water was measured using a 100 mL graduated cylinder. This water was then poured into the styrofoam cup that will be used to gather the hot water later. The water level was then marked using a pen on the inside of the cup. The water was then dumped out, and the cup was dried. Next, 100 mL of regular deionized water was measured using a 100 mL graduated cylinder, and the fish tank thermometer was placed in the water. Once the temperature was stabilizing in the graduated cylinder, the marked styrofoam cup was filled to the mark with hot water. Quickly, the temperature of the regular water was recorded immediately before it was poured into the styrofoam cup. The regular/hot water was mixed for a couple seconds, and the fish tank thermometer was then submerged into the water. After approximately 30 seconds, the temperature of the mixture leveled out, and was recorded. This was repeated three

    In the Heat of the Night takes place during the civil rights movement. Chief Gillespie in conjunction with the racist residents of Sparta, do not welcome outsiders, especially not a black man, which is obvious upon Virgil Tibbs unjust arrest at the train station. Gillespie appears as a corrupt, prejudiced, and narrow-minded police chief, yet he and Virgil continue working collectively to solve Colbert’s murder. Chief Gillespie appears to experience self-isolation and loneliness which he expresses in the scene in his house with Virgil. For example, Gillespie asks Tibbs if he has a family or if he is or has been married. Chief Gillespie reacts to Tibbs’ responses as a consolation of pity, yet they similarly share a common bond of employment

  • Calorimetry Lab Report

    The purpose of the lab is to understand how to calculate the calorimeter constant by using a calorimeter. This allows us to analyze the heat reaction of different substances. Calorimetry is a word that comes from both Latin and Greek. The prefix “Calor” in Latin signifies heat and the suffix “metry” in Greek means measuring. Therefore the word itself translates to measuring heat. Joseph Black, was the first scientist to recognize the difference between heat and temperature. Energy is always present in chemical and physical changes. The change of energy that occurs when there is a chemical change at constant pressure is called enthalpy. Enthalpy changes , as well as physical and chemical changes, can be measured by a calorimeter. The energy that is released or absorbed by the reaction can be either absorbed or released by the insulating walls of the instrument.

  • Chemistry: Magnesium Hydroxide And Citric Acid

    In this lab, I determined the amount of heat exchanged in four different chemical reactions only using two different compounds and water. The two compounds used were Magnesium Hydroxide and Citric Acid. Both compounds were in there solid states in powder form. Magnesium Hydroxide was mixed with water and the change in heat was measured using a thermometer. The next reaction combined citric acid and magnesium hydroxide in water. The change in heat was measured as well. For the third reaction citric acid was placed in water to measure the change in heat. In the last reaction, citric acid was combined with water. The heat exchanged was again measured. It is obvious we were studying the calorimetry of each reaction. We used a calorimeter

    Conduction, Convection, and Radiation Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers, Conduction, Convection, and Radiation. The first kind of heat transfer, conduction, is heat transferring through direct contact of materials. This would be the same thing as a pan on the stove. The heat from the stove touches the pan directly, therefore making the pan hot.

A reaction under kinetic and thermodynamic control can form two different types of products. A reaction under kinetic control is known to be irreversible and the product is formed quickly. A reaction under thermodynamic control is known to require rigorous conditions. It is also reversible. The final product is more stable than the product made by kinetic control. The chart below shows the two types of reaction coordinates:

  • Heat Transfer Essay

    Heat energy is transferred through three ways- conduction, convection and radiation. All three are able to transfer heat from one place to another based off of different principles however, are all three are connected by the physics of heat. Let’s start with heat- what exactly is heat? We can understand heat by knowing that “heat is a thermal energy that flows from the warmer areas to the cooler areas, and the thermal energy is the total of all kinetic energies within a given system.” (Soffar, 2015) Now, we can explore the means to which heat is transferred and how each of them occurs. Heat is transferred through conduction at the molecular level and in simple terms, the transfers occurs through physical contact. In conduction, “the substance
