Practical work brings science to life, helping students make sense of the universe around them that's why we've put practical work at the heart of our biology, chemistry and physics a-levels practical science allows scientific theory to transform into deep knowledge and understanding – scientific thinking through.
This is a step-by-step calorimetry practical with step-by-step instructions on how to calculate the amount of energy transferred (q) i incorporated this into the alternative fuels section of the gcse aqa syllabus but it could be done at any time i prin. Measuring energy transfers energy can be released in chemical reactions as light, sound or electrical energy but it is most often released as heat energy this allows us to easily measure the amount of energy transferred calorimetry measuring heat transfers is called calorimetry the diagram shows a simple calorimetry.
