Purpose: In this lab‚ we will heat up a metal rod and measure how much it expands. We will calculate its Coefficient of Linear Expansion‚ α‚ and prove the formula for thermal expansion‚ ΔL = αLiΔT. Also‚ we heat up a known volume of methyl alcohol and calculate its Coefficient of Volume Expansion‚ β‚ and prove the formula for volume expansion of a liquid ΔV = βViΔT. Equipment: Hollow Metal Rods of different metals‚ Steam Generator‚ Stand‚ Burner‚ Flexible Hoses‚ Motion Amplifier‚ Micrometer

Earth is the third planet from the Sun‚ and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System’s four terrestrial planets. It is sometimes referred to as the world or the Blue Planet.[22] Earth formed approximately 4.54 billion years ago‚ and life appeared on its surface within its first billion years.[23] Earth’s biosphere then significantly altered the atmospheric and other basic physical conditions‚ which enabled the proliferation

There is a fact that our planet is protected and supported by the tree all over the world. With the recent uncontrolled forest exploiting‚ some people think that this possibly leads to the end of the earth. In my point of view in this essay‚ if people keep destroying this green natural resource‚ they will soon face many serious consequences such as global warming‚ disaster‚ or even extinction. Firstly‚ it’s knowledgeable that people now have to suffer the climate change resulted by greenhouse

Our Earth is a living organism–an enormous being‚ of which we are parts. This is our planet‚ its destruction will make us all homeless. We are dependent on Earth and not the other way round. However‚ the thankless creature‚man‚ is unconcerned about the dangers that pose threats to our survival. The article by Nani Palkhivala deals with the concerns of the environmentalists at this eleventh hour and talks about the new awareness that has dawned upon our race. A holistic and ecological view of the

STRENGTHENING OF METALS There are 4 major ways to strengthen metals‚ and all work because they make dislocation motion more difficult. They also reduce the ductility: 1) Cold work (Strain Hardening) 2) Reduce grain size (Strengthening by Grain Size Reduction) 3) Add other elements in solid solution (Solid Solution Strengthening) 4) Add second phase particles (Precipitation or Age Hardening) • These mechanisms may be combined. • For example‚ the world’s strongest structural material (with
