Banana plants are often mistaken for trees‚ because their “false stem” or pseudostem resembles a tree trunk. However‚ trees are dicots

Density of Metals Problem: How does the mass and volume help determine the density of known metal samples? Hypothesis: When comparing the density of Zn(zinc) and Cu(copper)‚ you will find that Copper is more dense than Zinc. You can test this out by using the density formula D=m/v. Materials: * 2 metals (options: zn‚ al‚ or cu) * 3 samples of each metal (small‚ medium‚ and large) * Scale/Balance * Calculator * Water * Graduated Cylinder Safety: * Be prepared for your

The Metal Injection Moulding process (MIM)‚ considered as a development of the Powder Injection Moulding (PIM)‚ became‚ over the years‚ a competitive manufacturing process for small components‚ offering an alternative to other processes‚ more expensive to create these parts. History of the technology The PIM process was at first developed in the 1930s in the USA. This process was originally intended for ceramics. Then‚ during the Second World War‚ metal powders appeared. The process of Metal

Experiments with Metals and Ions of Metals Introduction Metals are similar in their physical properties in general‚ but they are not identical. Most of the metals are solids; few of them are liquids‚ such as mercury and cesium. Density of metals is not similar also. For example‚ sodium has density of 0.97g/cm3 while lead has density of 11.4g/cm3. Melting point of sodium is 98.0oC while for lead it is 327.6oC. Metals have the capability to lose electrons when they react with non-metals such as
