DEGRESS CELCIUS. Research Question: Does the mass(±0.005g) of various types of corrosive metals (iron‚ nickel‚ zinc‚ copper and tin) change when placed in a solution of 1 molar hydrochloric acid over a period of 8 days at an average room temperature of 24 degrees Celsius? Aim: To be able to record and understand if and why a change in mass (±0.005g) occurs in various types of corrosive metals that include iron‚ nickel‚ copper‚ zinc and tin when placed in a solution of 1 molar concentration of hydrochloric

and alloyed in the right proportion‚ it can also be very hard which makes it good for creating bolts and nuts as well as machine parts. Steel: Steel is an alloy of iron and carbon. The proportion of carbon to iron varies the hardness of the alloy‚ the ductility and the tensile strength. Steel can be made stronger than pure iron however is also less ductile. If steel is soft‚ malleable and ductile it is used for sheet steel‚ nails and wires. If it is hard and moderately ductile‚ it is used for

Steel is actually a mixture of iron with a small percentage of carbon. By using different ratios of iron to carbon‚ different properties are obtained for different steels. What are some different properties that might be valuable for different types of steel? Hardness‚ flexibility‚ density‚ etc. VI. Discussion:
