For the density of water‚ a clean and dry 100ml graduated cylinder was weighed and 50ml of water was added into the graduated cylinder. The graduated cylinder with water was weighed again to get its mass. For the density of a liquid other than water‚ a clean and dry 10ml graduated cylinder was weighed and 5.0ml of the different liquid samples (isopropyl alcohol‚ coconut oil and an unknown liquid) were added

Reggie Koch Professor Metcalf English 100 11-14-2007 The Beginning of the End of Oil The end of oil can mean an end to a lot of things in an industrialized lifestyle that we live in today. With more than 60% of the world passed their peak‚ this puts United States at a great risk because the U.S. alone uses more than 25% of the world’s oil. According to Tom Whipple‚ “Americans have consumed an average of 9.3 million barrels of gasoline a day so far this year‚ an increase of 0.6 percent from

Laboratory Report The title of the lab that we completed in class was The Law of Conservation of Matter. The purpose of this lab was to find out if matter can be created or destroyed in a chemical reaction. Dalton came up with the atomic theory‚ which included the law of conservation of matter. His theory was that matter cannot be created or destroyed and that chemical reactions only rearrange the way that atoms are combined; the atoms themselves don’t change. The procedure went like this

Wildlife & Conservation Statistics Extinction of Species • Every 20 minutes‚ the world adds another 3‚500 human lives but loses one or more entire species of animal or plant life - at least 27‚000 species per year. (Source: PBS) • At the present rates of extinction‚ as many as 20% of the world’s 7-15 million species could be gone in the next 30 years. This rate of extinction has been unprecedented since the disappearance of dinosaurs 65 million years ago (Source: WWF). Habitat Destruction (Source:

Experiment 4 Inelastic Collisions‚ Conservation of Momentum and Non Conservation of Kinetic Energy Preparation Prepare for this week’s experiment by studying Newton’s Laws‚ linear momentum‚ and kinetic energy. Principles In this experiment you will study a collision where a moving object strikes and sticks to an initially motionless object. When the colliding objects stick together the collision is said to be completely inelastic. The net momentum of the system should not change‚ but the

The birth and growth of human civilization and culture has been very intimately connected with the forests. Forests have had a great influence on human thought and way of living. For example‚ the Vedas and Upanishads‚ the oldest known religious‚ philosophical and literary monuments of mankind are the direct products of forest-life in ancient India. The Aranyakas or the Forest Texts form an integral part of these oldest testaments of human wisdom and philosophy. They are called so because they were
