Kalorimeter Bom Download Report. Published on Jan View 54 Download 1. Sejumlah sampel ditempatkan pada tabung beroksigen yang tercelup dalam medium penyerap kalor kalorimeterdan sampel akan terbakar oleh apilistrik dari kawat logam terpasang dalam tabung. Kalorimeter bom terdiri dari tabung baja tebal dengan tutup kedap udara.

Sejumlah tertentu zat yang akan diuji ditempatkan dalam cawan platina dan sebuah”kumparan besi yang diketahui beratnya yang juga akan dibakar ditempatkan pula padacawan platina sedemikian sehingga menempel pada zat yang akan diuji.

Kalorimeter bom kemudian ditutup dan tutupnya lalu dikencangkan. Setelah itu “bom” diisi dengan O2 hingga tekanannya mencapai 25 atm. Kemudian “bom” dimasukkan ke dalam kalorimeter yang kalori,eter. Setelah semuanya tersusun, sejumlah tertentu aliran listrik dialirkan ke kawat besi dansetelah terjadi pambakaran, kenaikan suhu diukur.

Kapasitas panas atau harga air bom,kalorimeter, pengaduk, dan termometer ditentukan dengan bkm terpisah denganmenggunakan zat yang diketahui panas pembakarannyadengan tepat Biasanya asam benzoat Keterangan: Termometer berguna untuk mengukur suhu. Pengaduk berguna untuk mengaduk air pendingin. Katup oksigen untuk memasukkan oksigen dari tabung.

Kawat penyala untuk membakar.

Bom yaitu tempat terjadinya pembakaran. Jacket air yaitu jacket untuk peletakan bom. Hal yang Perlu Diperhatikan dalam Pengoperasian. Suhu pembakaran pada bomb kalorimeter tiap menit yang dilihat pada digital temperature indicator. Kalorimetwr gas Oksigen yang diberikan pada bom. Isi gelas kimia dengan 50ml NaOH3. Isi gelas kimia dengan 50ml HCL 0,1M. Ukur dan cata suhu setiap larutan.

Tutup kalorimeter dengan karet penyumbat lalu aduk campuran larutan. Catat suhu campuran larutan. The bomb vessel is not charged at all, or charged with an inert gas.

Kalorimeter bomb

A small kalkrimeter is burned and the energy is displayed. But if the substance can be ignited by heat, then the DDS range of bomb calorimeters can measure it. Typical applications are igniter caps and charges. Thevessel is at present used for quality control. The speed of combustion is not measured. The calorific value of fuel determines the amount of energy contained in it – this means that a fuel of high calorific value will give more energy and thus kqlorimeter propulsion to the vehicle than the fuel of lower calorific value.

All liquid fuels can be analyzed in a bomb calorimeter unit.

Non-Traditional applications which are applications that are not referred to in any standard publication. The instrument produces repeatable and accurate results with non-conventional samples. However, thebomb calorimetercan be used in a comparative fashion in quality control in animal feed production and optimization of feed consumption. The bomb calorimeter is used in animal feed research, Department of Agriculture, Department of Animal Sciences, Universities and private industry.

The aim isto improve the nutritional value of the feed or optimize the nutritional absorption by animals. Therefore thebomb calorimeteris ideally suited for incoming control of raw products during oil production.

Consequently, any food production, which uses oil in the process can use the calorimeter to measure the oil content of the final product. Since we are all concerned with the daily intake of calories, the instrument is used to control the use of oil during production of potato chips, canned beef and fish.

Heat is evolved in exothermic processes and absorbed in endothermic kalorieter such processes include chemical reactions, transitions between the states of matter, and the mixing of two substances to form a solution see thermodynamics.

A number of different units are used in heat measurement, e. The apparatus used in heat measurement klaorimeter called a calorimeter. The measurement given by the most common type of calorimeter depends upon the temperature change in a fixed quantity of water or some other liquid whose heat capacity is known when heat is transferred between the water and an exothermic or endothermic process.

If the temperature change is not too large, then the heat transferred is equal to the heat capacity of the water times the mass of the water times the change in temperature. The accuracy of this method of heat measurement depends on the assumption that all the heat transferred in the process passes into or out of the water in which the temperature change is measured, no heat being lost to the environment and none being absorbed by the walls of the container.

The amount of heat given off by the combustion of a fuel can be determined very accurately in the so-called bomb calorimeter, which consists of a combustion chamber the “bomb” set in another chamber filled with water.

Heat generated by combustion of the fuel is transmitted to the water, raising its temperature. The calorie content of food is tested this way. Calorimeters are also employed to measure kaloriemter energies of elementary particleshttp: Hasil Percobaan Kalorimeter Bom Documents. Laporan Praktikum Kalorimeter Bom Documents.
