Chemistry: Research task 1 5.1- define the terms mineral and ore with reference to economic and non-economic deposits of natural resources The term ‘ore minerals’ is commonly referred to as economic minerals Mineral: naturally occurring compounds. Rocks are mixtures of various minerals. Most minerals are lattice structures‚ both ionic and covalent. Economic minerals have been divided into two main categories: Metalliferous minerals- mined to extract a metal Industrial mineral- either has

they do begin to deplete. For example‚ copper‚ in the early 1960’s telephone use in the United States was expanding enormously‚ at the time the only way to carry the data over telephones was over copper wire‚ so as telephone use began to expand to new parts of the United States‚ the demand for copper began to rise‚ as the demand of copper began to rise so did the price. The outcome of this scenario is that people begin to worry we would not have enough copper to wire the entire country for telephone

There are‚ and always have been many theories on how and why Oetzi the Iceman was killed. Many theories say he was murdered by an enemy‚ tracked down and hunted after surviving a battle with an enemy clan‚ or even that he was sacrificed to the god of the mountains. There is no way to surely determine how he died to a tee‚ and ever since the Iceman’s discovery‚ new evidence has been consistently presenting itself‚ suggesting new and improved theories‚ while also dismissing the old.

Physics assignment Aim To determine which factors affect the resistance of a conductor‚ and the mathematical relationship that exists between these variables. Hypothesis Copper wires would be a better conductor than nichrome wires because it would yield less resistance when they have same cross-sectional area‚ length and temperature. Resistance would be increased when length wires increased. Resistance would be increased when cross-sectional area of wires decreased. Resistivity of wires is a factor

TOPIC 2 Metals The History of Metals * Uses of metals through history: * Copper Age (3200-2300 BCE) – copper and tin were most common metals‚ and were used for ornaments‚ weapons and tools. * Bronze Age (2300-700 BCE) – copper‚ tin and bronze were used for tools‚ weapons and transport. They produced bronze by heating copper and tin with charcoal. * Iron Age (1000 BCE – 1 CE) – iron steel and lead was used for tools‚ weapons and pipes. Iron is much harder than bronze.

Koko was a Gorilla that was trained sign language at an early age by her primary caregiver Penny. Penny performed an experiment‚ testing to see if primates like gorillas can communicate in sign language with humans. The reason Koko was so special because she is the longest animal study in history. It infatuated the public when Koko was first in the public eye on the cover of National geographic holding kittens. Koko changed how people viewed animals‚ and got people to their emotions. Before this
