Thermochemistry: Enthalpy Changes in Simple Processes

The primary objective of this lab is to be able to determine the specific heat of a reaction by using a calorimeter. A calorimeter is a device used to determine the specific heat of chemical reaction or a physical change. The specific heat a reactions is used to refer to the amount of heat that is lost or gained when one gram of a particular substance increases or decreases by one degree Celsius. When a chemical reaction occurs in an open container most of the energy gained or lost is in the form of heat. Almost no work is done (i.e. nothing is being moved). Heat flows between the system and surroundings until the two are at the same temperature, when a chemical reaction occurs in which the system absorbs heat, the process is endothermic (it feels cold). When a chemical reaction occurs in which the system produces heat it is exothermic (it feels hot)…

Specific Heat of a Metal

First you will fill a 250 mL beaker with water then put it on the hot plate. Second you will mass and record the mass of a metal sample. Make sure you also record the metal's number. Gently place the metal sample in the beaker using tongs. While waiting, set your calorimeter. Put the calorimeter on the balance, zero it out, and fill it with 5/8 full of water. Record exact amount. Start a new experiment of the data collection system, and the temp of the water in the calorimeter as the water's initial temp. After the water has boiled for a while, use tongs to remove and quickly place it in the calorimeter. Put lid back on. Swirl the calorimeter and observe the temp every 15 secs until it drops. Record the max. temp as your final temp for both the water and metal. If you have time, do it over again!…

Lab Report Caloric Content of Food

PURPOSE: In this lab we will have the opportunity to measure the energy in a variety of foods, by heating/burning a portion of the food item and catching the heat released into a known mass of water in a calorimeter. We will also identify units of measuring heat such as calories and joules. We will use basic lab equipment provided in our labpaq and we will use several household items as well. We will follow all safety requirements and standard procedures for this lab.…

Thermochemistry

Purpose: This lab taught procedures for determining heat of capacity of a calorimeter and measuring enthalpy of change for three reactions. It also enforced methods of analyzing data obtained through experimentation and calculating enthalpy. These procedures are used in the branch of thermodynamics known as thermochemistry which is the study of energy changes that accompany chemical reactions. Concepts from this lab can be used to determine the potential energy of a chemical reaction. Much of the energy people depend on comes from chemical reactions. For example, energy can be obtained by burning fuel, metabolizing of food or discharging a batter.…

Calorimetry And Specific Heat Lab Report

While waiting on the water to boil, retrieve a piece of unknown metal to be identified and record its ID letter and its mass. Once the mass of the unknown metal is recorded, put the metal into the boiling water. While waiting on the water and the metal to achieve the same thermal equilibrium, get a coffee cup and measure its mass. Then pour about 50mL of water into a coffee cup, measure the mass of the water and the coffee cup and then determine the mass of the water alone (mass of water and coffee cup – mass of coffee cup). Record the temperature of the boiling water on the hot plate with the metal and then record the temperature of the water in the coffee cup before adding the metal. Use the string attached to the metal to transfer the metal from the hot water bath to the calorimeter. Using a piece of cardboard to cover the top of the calorimeter, record the temperature of the water in the calorimeter. Repeat the experimental procedure three more…

Heat Of Combustion Lab

In this lab, we will measure the heat of combustion, or calorimetry, of a candle and compare the found quantity with known values for other hydrocarbons. The calorific value is the total thermal energy released when a substance goes through complete combustion with oxygen. In order to achieve the purpose of this lab, we must first determine the mass of the tea candle. Then, we will determine our room temperature, measure about 100 mL of chilled water, and then pour the water into the given empty soda can. Afterwards, we will set up the soda can and candle in a stacked-style apparatus - the candle underneath the lifted can. After we have set up the apparatus, we will carefully light the candle and gently stir the water with a stirring rod. We will continuously check the heat of the water with our thermometer in order to make sure the temperature is neither too high or too low. After the water is heated above room temperature as it was below room temperature at the start, we will extinguish the flame…

Caloric Content of Food

The first step in this experiment was to weigh and record an empty 100mL beaker. Then fill the beaker approximately halfway, weigh it and record the weight. Record the weight of the water in the beaker. Place a piece of aluminum foil on a table top. Place a wire burner stand with the beaker full of water in the center of the aluminum foil and place a candle next to the rack. Measure the weight of one marshmallow and the weight of one fork. Record both measurements. Then place the marshmallow on the fork measure and record the weight of the marshmallow and fork together. That weight should equal the measurements of the fork and marshmallow combined in the previous measurement. Measure and record the temperature of the water in Celsius and record it. Light a candle. Put the fork with the marshmallow over the candle flame. Remove the marshmallow from the flame right after it sets on fire and place it under the beaker of water. Hold it under the water until it is completely done burning. Make sure to stir the water frequently with the thermometer. When the marshmallow has burned down as much as possible, remove from under water and record the temp of the water. Then record the weight of the fork with leftover marshmallow on it. Subtract that measurement from the previous measurement of the fork with pre-burned marshmallow. Record the measurement of the marshmallow residue.…
