56.0 mL of two different liquids are poured through a funnel with a narrow exit tube, and the time for all of the liquid to flow through is recorded. Here are some results: time to flow through funnel trial Liquid X Liquid Y 1.60 s 3.62 s 1.52 s 3.44 s 1.44 s 3.56 s Note: the two liquids have the same density. Which statement below is true about these liquids based only on the data in the table? O The intermolecular forces in liquid X are stronger than those in liquid Y. The boiling point of liquid X is higher than the boiling point of liquid Y. The viscosity of liquid X is greater than the viscosity of liquid Y. The surface tension of liquid X is greater than the surface tension of liquid Y. The viscosity of liquid X is less than the viscosity of liquid Y. 3.
Q6.1 There are always imperfections in a crystalline structure. Perfect order never exists throughout crystalline materials on an atomic scale. All crystalline structures contain large numbers of defects and imperfections. Name and explain two types of defects in crystalline solid. Q6.2 Heat treatment may be used to improve the mechanical properties of some aluminium alloys. Heat treatment for aluminium alloys is done via a process called precipitation hardening also known as age hardening. Explain the steps of age hardening and name one example of aluminium alloy which can be strengthened by age hardening.
You need to find out the maximum NPV of a hypothetical iron ore open pit as shown below. The iron ore grade is 72% and recovery is 90%. The market price of iron ore is $100/ton. The ore and waste block size are 30 by 30 by 30 m3 and annul production of six blocks (mining + stripping) is there. The mining cost is $35/ton and the stripping cost is $25/ton. The density for the ore and waste is 4.5 ton/m3 and 2.5 ton/m3 respectively. Assuming initial investment $50 million the interest rate is 5% per year.
