Rajah 2 menunjukkan suatu set radas dan bahan yang digunakan dalam eksperimen ini yang menunjukkan suhu awal air adalah 290 C. Justeru itu. Tenaga haba ini seterusnya diserap oleh air di dalam tabung didih.4551/3 Answer all questions Jawab semua soalan Question 1 / Soalan 1 Energy value or calorific value is the quantity of heat produced when one gram of food is completely oxidized or burnt down. kandungan tenaga dalam pelbagai sampel makanan adalah berbeza-beza berdasarkan kelas-kelas makanan. Sekumpulan pelajar tingkatan 4 telah menjalankan satu eksperimen untuk menentukan nilai tenaga untuk sampel-sampel makanan berikut dalam Rajah 1. Hence.up used in this experiment showing the initial water temperature of 290 C. P Q R Diagram 1 / Rajah 1 Diagram 2 shows the apparatus set. A group of form 4 students carried out an experiment to determine the energy value for the following food samples in Diagram 1. This heat energy is then absorbed by the water in the boiling tube. Diagram 2 / Rajah 2 PANITIA BIOLOGI SMKGB 2 . the energy content in food varies among food samples according to their classes of food. Step 3: The boiling tube is clamped to a retort stand with thermometer placed in it. Apabila pembakaran lengkap. 20 ml air suling dimasukkan ke dalam tabung didih yang bersih menggunakan silinder penyukat. the burnt bread is placed below the boiling tube. Step 7: The water is stirred gently with the thermometer. Roti (P) dilekatkan pada pin dan dibakar di dalam api gas labor. Step 9: The energy value of bread is calculated using the following formula: Energy value = 4. Step 6: When completely burnt. Air dikacau secara perlahan menggunakan termometer. roti yang dibakar diletakkan di bawah tabung didih. Jadual 1 menunjukkan suhu tertinggi selepas sampel makanan dibakar dengan lengkap. Step 8: The final temperature of water is recorded using the thermometer Suhu akhir air direkodkan menggunakan termometer.2 (Jg-1˚ C) x jisim air (g) x kenaikan suhu (˚C) Jisim sampel makanan (g) Step 10: Step 1 until 9 are repeated using anchovy (Q) and cashew nut (R) Langkah 1 hingga 9 diulangi menggunakan ikan bilis (Q) dan kacang gajus (R) Table 1 shows the highest water temperature after the food sample is completely burnt down. Step 4: The initial temperature of water in the boiling tube were measured and recorded by using a thermometer. PANITIA BIOLOGI SMKGB 3 .4551/3 The following steps were carried out: Langkah-langkah berikut telah dijalankan: Step 1: Small pieces of bread (P) is cut off and the mass is weight and recorded using a balance. Tabung didih diapit pada kaki retort dengan termometer diletakkan ke dalamnya. Step 2: 20 ml of distilled water was placed into a clean boiling tube by using a measuring cylinder. Sebahagian kecil roti (P) telah dikerat dan jisimnya ditimbang serta direkodkan menggunakan penimbang. Jisim awal air di dalam tabung didih diukur dan direkodkan menggunakan thermometer Step 5: The bread (P) is attached to a pin and burnt in a labour gas flame.2 (Jg-1˚C) x mass of water (g) x temperature increase(˚C) Mass of food sample (g) Nilai tenaga roti dihitung menggunakan formula berikut: Nilai tenaga = 4. 6 Q Anchovy Ikan Bilis 0.4551/3 Type of food sample Mass of food sample Final temperature of Increase in water Jenis sampel Jisim sampel water temperature makanan makanan (g) Suhu akhir air (˚C) Pertambahan suhu air (oC) P Bread Roti 0.2 Table 1 / Jadual 1 PANITIA BIOLOGI SMKGB 4 .8 R Cashew nut Kacang gajus 1. .......................................................... ..................................................................................................................................................................................................
