Aim: to find the specific heat capacity of a metal using the method of mixtures. Physics java labs before you start your lab report, it might be useful to look at a sample report measure, and plot the phase disgram of water to determine the mass of the unknown quantity of water by comparing to the known values of the latent heats of melting and boiling, or to the specific heat capacity of water. British physics olympiad 2011 – 12 bpho experimental project teachers' guidelines the project this year is to investigate heat capacity and in particular the specific heat capacity of two materials which in experiment should be written by the student in their conclusion and they should be responsible. You can view a table of specific heat on hyperphysics water actually has a very high specific heat compared to most substances the reason for this has to do with the number of degrees of freedom of the molecules if i add a calorie of heat to a gram of water and a calorie to a gram of aluminum, the aluminum will warm up. (heat) 'in the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see a pretty experiment is in itself often more valuable measurement of the specific latent heat of fusion of ice expected to know the conclusion or result of an experiment and appropriate precautions. And the specific heat c can be determined the calorimeter is made of copper and sc = 0093 cal g-1 ec-1 experiment 1 arrange the calorimeter with the inner vapour pressure of water references gr noakes new intermediate physics copies are available at the resource centre the experiment. Chemistry lab: specific heat of a metal laura e bishopintroduction - (also includes pre-lab information): one.
I would like to ask,if one is conducting an experiment on determining the specific heat capacity of water using the following apparatus : thermos with heater power supply thermometer timer measuring cylinder in what ways can this experiment be improved so that it could be used to determine the specific heat capacity of. Calorimetry - specific heat and latent heat name: lab partner: section: 31 purpose the purpose of this experiment is to study the relationship between heat and tempera- calorimetry will be used to investigate specific heats of materials and the latent heat write a detailed conclusion about what you have learned. Principle a measured quantity of water is heated with a heating coil the electrical heat output is determined from the temperature increase and the heat energy, the specific heat capacity of water is calculated this calculation is performed unde.
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. Thermal energy losses are something that students can investigate further, to obtain a more accurate value of the specific thermal capacity the guidance note cooling corrections suggests a procedure for controlling such losses a less sophisticated, but equally valid, approach is to repeat the experiment (the block needs.
This is a simple experiment to measure the specific heat (also called specific heat capacity) of any fluid step 5: conclusion picture of conclusion in this experiment, the specific heat of water was measured by heating a small quantity of water with a known power input, and measuring the temperature. Example of error propagation: find the specific heat of copper actual student data : mal = 61 ± 05 g tequil = 345 ± 05◦c ch2o = 1000 cal/(g ◦c) mcu = 200 ± 05 g t1 = 23 ± 05◦c cal = 0215 cal/(g ◦c) mwateradded = 105 ± 05g t2 = 96 ± 05◦c derived formula for specific heat of copper: ccu = calmal(tequil − t1). Metal based on its specific heat a lab preparation note: use a fast-response temperature probe to measure the change in temperature of a known mass of water basic calorimetry set (1 metal object and 2 calorimeter cups) balance graduated cylinder, 50-ml 20 cm braided physics string stir rod 300 ml water.

Because you know which metals you have analyzed and have the theoretical specific heat values for those metals under table 1, you should be able to calculate the percent error of your experimentally derived value for this lab report, we are required to calculate the heat lost by the aluminum and the lead. Leave all other data the same and recalculate the specific heat of the metal now assume that for some reason your measured changes in temperature are off by 1 °c add 1°c to the change in temperature of the metal add 1°c to the change in temperature of the water leave all other data the same and recalculate the.
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. Physics lab report specific heat capacity of a metal aim: the aim is to determine the specific heat capacity of the unknown metal provided background information: specific heat capacity is the quantity of heat required to raise the temperature of a unit of mass of a substance by a unit change in. Temperature is measured in degrees celsius (°c) or in kelvins (k), while the specific heat of that material is measured in specific heat capacity of metals peter jeschofnig, phd version 42-0277-00-01 lab report assistant this document is not meant to be a substitute for a formal laboratory report the lab report. Part of ncssm core collection: this video shows the collection of data to determine the specific heat of a metal please attribute t.
1 experiment 10 specific heat and heat of fusion preparation study for this week's quiz by reviewing harmonic motion and by reading the sections of your book that cover heat, heat of fusion, and specific heat capacity look up the definition of a mole principles temperature and heat temperature and heat are not the. In a lab-based chemistry class, students will investigate the topic of specific heat and heat capacity using different temperatures of water and solids students will collect information based on observations and apply the mathematical equations of specific heat and heat capacity to their data students will write a lab report in. The goal of this experiment is to experimentally determine the specific heat capacity of water and compare it with the table value let us note that if we know the specific heat capacity c of a substance of mass m, which is heated ( cooled) by δt, the heat q supplied to (taken out of) the substance can be. Physics practical specific heat of a solid experiment video is the heat capacity per unit mass heat capacity of a body is the quantity of heat required to raise the temperature of the body by 1 degree centigrade the experiment determines the specific heat of various solids by the method of heat transfer.
