Properties of Substances- Gr.12 Chemistry Final Lab Report Lab: Properties of Substances M. Nguyen SCH4U April 27‚ 2012 Abstract The purpose of this experiment was to use a variety of tests to identity the type of bonds which are present in each solid. Various substances (paraffin wax‚ sucrose‚ sodium chloride‚ tin‚ and silicon dioxide) were experimented and identified with tests for hardness‚ solubility‚ conductivity‚ and the time for the solid to melt with a candle and Bunsen burner

Marybeth Brooks Physics Lab III Specific Heat Capacity Lab May 25‚ 2011 Abstract The specific heat capacity of various metals can be calculated and compared to accepted literature values. Dropping heated metal samples into a calorimeter filled with water and then measuring the change in the temperature of the system accomplished this. The metal samples were heated in a boiling water bath and were assumed to be at 100 C when they were removed. It was added to a calorimeter and stirrer

FORMAL REPORT ON HEAT CAPACITY RATIOS OF GASES ABSTRACT This report discusses an investigation of the heat capacities of Helium‚ Nitrogen‚ and Carbon Dioxide. To accurately determine experimental values for the heat capacity of each gas‚ the heat capacity ratio was calculated from measurements of the speed of sound in each gas. An apparatus designed to measure the wavelength and frequency of sound waves in each gas was used to determine the speed of sound as a frequency was passed through each
Premium Oxygen Energy Temperature
Abstract Different substances react in various ways when exposed to heat. The amount of energy necessary to heat a certain amount of water by one degree is different than that of another liquid or substance. The technical term used to determine this characteristic is called heat capacity or specific heat capacity. The purpose of this experiment is to find the heat capacity of water‚ orange juice‚ and olive oil. A couple of very specific equipment is needed in order to complete this experiment

Experiment 1 The Heat Capacity Ratio of Gases Purpose The purpose of this experiment is to calculate the heat capacity ratio of gases‚ Helium‚ Nitrogen and Carbon Dioxide‚ and compare with their theoretical values. Introduction Thermodynamics is the study of heat as it relates to energy and work. There are various properties which all relate to each other when determining the characteristic of a certain substance. One of such properties is heat capacity‚ which is the amount of heat energy required

Title: Specific Heat Capacities of Metals Experiment Date: 3/28/2012 Report Date: 4/4/2012 Purpose: The purpose of the lab is to measure the specific heat capacities of aluminum‚ steel and brass. Theory: The amount of heat (ΔQ) required to change the temperature of an object is proportional to the mass (m) of the object and the temperature change (ΔT) of the object. ΔQ= cmΔT where c is called as the specific heat capacity of the material. In the calorie units system the unit of quantity

Aim: i) To find the relationship between supplied energy and change in temperature of water. ii) To find the specific heat capacity (SHC) of water. Hypothesis: As time increases so does the temperature since the water is exposed to the heated wire for a longer period of time. Variables: The Dependent Variable is the temperature of the water‚ and since the Energy is calculated using temperature it is a dependent variable as well. The constant variables are the voltage and current. Theory:

Lab 2 Report- Identification of Substances by Physical Properties The purpose of this lab was to see how certain substances; Naphthalene‚ Toulene‚ and and 2 unknowns (one liquid‚ one solid) react with 3 different solvents. To identify the two unknowns‚ testing needs to be done to find the density of both the liquid and the solid‚ determine the melting point of the solid‚ and the boiling point of the liquid. The Physical Properties of Pure Substances Table can then be used to compare the observed
