Purpose: to calculate the specific heat of a metal using mass and temperature data obtained by using a calorimeter materials needed: hot plate, beakers, thermometers, styrofoam cups, tongs, copper strips, aluminum strips, lead strips, and zinc strips. This lab will help you to be able to explain what specific heat is and find the specific heat of a metal using household objects after completing. Optional fun lab: specific heat capacity of water lab experiment the world climate does not respond immediately to the external forcings applied by human activity a simple way to show why this is so is to make some simple observations about the heat capacity of water.

When an object gains or loses thermal energy (heat), its temperature changes the magnitude of the temperature change depends on the size 50 g of the object, its composition, and on how much heat is added 100 g the module simulates heating a block with a small bunsen burner the block always starts at 200 °c. The porpoise of these is to determine the specific heat also known as heat capacity, the specific heat is the amount of the heat per unit mass required to raise the temperature by one degree celsius the relationship between heat and temperature changed is usually expected in the form shown the relationship does not. Water graduated cylinder, 100-ml the “specific heat set” (ap9220) is ideal for this activity see the tips section safety precautions handle hot metal samples with care to avoid burns wear chemical splash goggles whenever working with chemicals, heat, or glassware in the lab procedure recruit student volunteers to. Experiment 7 specific heat capacity lab (part 2) (determine the specific heat of an unknown metal) when substances at different temperatures are brought into contact they experience thermal interaction during this interaction heat is lost by the warmer substance and gained by the cooler substance this process.

Example #1: we are going to determine the specific heat of copper metal now this has already been done many times, so the value is available in reference books we will pretend that is not the case obviously, we need some pure copper, so we take a small piece of it let's say we use 150 grams the shape does not. Lab 04: specific heat introduction not everything heats up the same way if you have ever boiled water, you probably already know this the metal saucepan gets very hot very quickly it is soon too hot to touch but the water in the pan takes much longer to get warm heat is energy, and what you are seeing is that the. The aim of this lab exercise is to show that the composition of a metal cylinder can be established using a laboratory derived specific heat introduction: specific heat is a property that varies from substance to substance specific heat is a measure of the number of calories needed to raise 1 gram of that substance 1 degree. The specific heat capacity of a solid or liquid is defined as the quantity of heat required to change the temperature of a unit mass of a substance through a unit change in temperature our result from this experiment was somewhat close to the specific heat capacity for water, but still off the mark we were off by 1588 j/kg /oc.

Specific heat experiment let's measure the specific heat of a piece of brass, aluminum or plastic click the material would you like to use (c) copyright 1999 all rights reserved. In this guided lab you will determine the specific heat of an unknown solid you will place the solid into boiling water for a sufficient amount of time that it reaches the boiling point of the water you will then place it in cold water and monitor the temperature change you will then set the heat lost by the hot solid equal to the.

[type text] lab: specific heat summary students relate thermal energy to heat capacity by comparing the heat capacities of different materials and graphing the change in temperature over time for a specific material students explore the idea of insulators and conductors in an attempt to apply their knowledge in real world. Calorimetry lab - specific heat capacity introduction experience tells us that if a hot piece of metal is added to water, the temperature of the water will rise if several different metals having the same mass are heated to the same temperature and added to the same amount of water at the same temperature, will the final. One characteristic or property of all solids and liquids is something called the specific heat, abbreviated as cv this quantity represents the amount of heat required to raise or lower a given quantity (a gram or a kilogram) by one degree water has an extremely high specific heat (1 calorie per gram per.

The specific heat of a substance is unique and allows scientists to determine the substance's identity plan your 60 minutes lesson in science or chemistry with helpful tips from rachel meisner. Introduction equal masses of aluminum and lead are heated in boiling water the metals are then placed in separate beakers containing equal volumes of room temperature water the temperature change in each amount of water is measured and specific heats can be determined equations using the mass of the metal,.

  • In your lab exercise, you will design and use a calorimeter to determine the metals that compose your washers and weights see table 1 for a list of specific heat values for various materials to calculate specific heat, you use the following equation: q cm t = ∆ where q represents heat needed to change temperature.
