Essays on Second Law Of Thermodynamics

Abstract

This essay briefly describes the meanings of the first law and the second law of thermodynamics. Thermodynamics, as the name illustrates, is the field of science where the dynamics of quantities including but not limited to heat and temperature and their relationship with energy, work, entropy etc are dealt with. The first law of thermodynamics is a version of the principle of conservation of energy. It establishes a theoretical limit on how much work can be output when a certain amount of energy is available and vice versa. The second law of thermodynamics is a bit more subtle and ...

Which is a better choice at the grocery store: paper bag? Plastic bag? Or tissue bag? Explain your answer.The best choice at the grocery store is to bring a used bag. Paper bags, plastic bags, and tissue bags all have individual issues associated with their use. Paper bags come from a renewable source, and are biodegradable. Despite this, they require more energy to make and are less likely to be reused. Plastic bags are not biodegradable but consume less energy to be made than paper or tissue bags. Tissue bags are the highest energy consumptive option, but are more ...

Introduction

At times, industries require the temperatures to be kept below the ambient for some processes to be effective. To do so, they must design ways to eliminate the excess heat generated by machines and introduce an artificial room temperature lower than the ambient. They must effectively eliminate temperatures above the ambient. A refrigerator is thus required in these operations. This refers to a device that can maintain the temperature below the ambient. The primary objective of a refrigeration process is to lower the temperature through heat removal. Since its invention, refrigeration has seen used in many industrial and household ...

Ted Talk as an organization is a platform to share ideas with a key focus on technology, entertainment and design, on a myriad of topics from business, science and global issues. Dan Cobley formerly of Google shared his presentation in Ted Talk with his topic being “What physics taught me about marketing”. After listening to Dan Cobley’s Ted Talk the first thing that is evidenced is that any and everything can have a connection, all we need is an introspective review, since from a general perspective marketing and physics have nothing in common. The principles of marketing and ...
