The goal of this lab was to determine the heat of fusion of ice (or water). According to Chem.Libretexts.org, Heat of fusion is where solids are heated to a specific heat capacity (The number of heat units needed to raise the temperature by 1 degrees) in order to break the bonds that are keeping them attached, which is called the attractive force. This lab also dealt with the concept of the direction in which a temperature follow. According to chemistryexplained.com, temperature is the measure…
Convection is a type of heat transfer that only occurs with liquids and gases because it involves the liquids and gases physically moving, which a solid is unable to do. Convection happens when there is a difference in temperature between the two parts of a liquid or a gas. The warmer part rises because it expands and gains more energy and the cooler part sinks because it becomes denser and loses energy. Heat can also be transferred without the presence of any particles. This transfer is called…
3 Ways To Boost Furnace Effectiveness When the warm air inside your house leaks out quickly, your furnace will have to work harder than normal to keep your home warm. Having walls, ceilings, and floors that are properly insulated will go a long way with keeping the hot air in, but they are not enough. Windows are one area where air tends to leak out the most, and if you ignore them, your furnace won’t be operating at optimal efficiency. Double-Pane Windows If your home is older and still has…
8. Thermoregulation is keeping the body's temperature controlled or regulated. 9. The portion of the brain that contains sensors that monitor body temperature is the hypothalamus. 10. a) Two mechanisms the body uses to cool itself are the blood vessels dilating to radiate heat, and sweat glands increasing to increase sweat production. b) Two mechanisms the body uses to heat itself are the blood vessels constrict, reducing heat, and muscles beginning to shiver, generating heat. 11. a) The…
The Internet functions as the __________, and the Web (WWW) is __________ that runs on the Internet. a) transport mechanism; an application b) information architecture; a browser c); protocol; a search engine d) hardware; software 39. Which of the following is not a characteristic of intranets? a) Portals (gateways) that provide easy and inexpensive browsing and search capabilities. b) Company-owned networks that use IP technology to securely share part of a business’s information or…
company's direct emissions. Direct GHG emissions occurring from sources that are owned or controlled by the company (ie, sources within the organisational boundary). For example, emissions from combustion of fuel in owned or controlled vehicles. The GHG Protocol and ISO 14064-1 require Scope 1 emissions to be reported. Options for calculating scope 1 emissions include: i. Method 1 – using default emissions factors derived from the latest version of the National Greenhouse Account Factors;…
1) Apple Pay In the spring session of 2014 apple released apple pay to provide a seamless transfer of money between two parties. This was a move to position apple to further pursue further transactions without the need to pull out a spate card. In the future it is hope that apple pay would act also like a security card, and transport capabilities that can be used to access buildings and transport options. Apple pay in the meanwhile has to further adapt and conform to counteract fraudulent and…
computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and…
Kyoto Protocol to the UNFCCC 2005 Greenhouse gas emissions have continuously risen not only due to natural activity but human as well; there is a strong relationship between anthropogenic factors and global climate change. The Intergovernmental Panel on Climate Change has estimated that average global temperatures will rise 1.4-5.8 C by 2100 if greenhouse gas emissions continue to increase (York, 2005). A call for action was necessary so the UNFCCC began to discuss the Kyoto Protocol in 1997.…
China has been at the top of the international agenda when bringing up the issue of climate change and this is because of the controversial position of the Chinese government on the matter throughout the years. China has ratified the Kyoto Protocol; nevertheless the country was exempt from committing to an emissions target reduction since China was not one of the main contributors to global warming during the period of industrialization that is believed to be the cause of climate change (Feldon,…
