    Calculating the specific heat of a metal

    4 star(s)

    2. While the water was heating, the mass of a clean, dry 50-mL beaker was determined and recorded. Between 80 g and 120 g of lead shot was then added to the beaker and their combined mass was measured and recorded. 3. The lead shot was then transferred to a large, dry test tube. The utility clamp was used to suspend the test tube in the boiling water; the lead shot was below the level of the water in the beaker. The test tube was then left in the boiling for 10 minutes. 4.

Whilst Chemistry is a universal science, studying it at IB is quite different from other courses. The most distinctive difference is that it has considerably more breadth in the coverage of topics. The 11 topic core include: Quantitative Chemistry, Atomic Structure, Periodicity, Bonding, Energetics, Kinetics and Organic Chemistry.

The seven optional topics include modern analytical chemistry, human biochemistry, medicines and drugs, food chemistry, chemistry in industry and society, further organic chemistry and environmental chemistry. You'll be expected to become adept at practical laboratory work, data collection and manipulation, and build a strong scientific awareness. External assessment consists of three written papers, which you may find easier to face having accessed the Marked by Teachers collection of IB Chemistry essays. Internal assessment, which makes up 24% of the marks, consists of an interdisciplinary project, a variety of short and long-term practical investigations and some subject-specific projects.
