There are many definitions of thermal comfort, which depends on the aims and expectations of those who defined it (Chappells, and Shove, 2004). Jiao (2010) stated that, the rate at which human body gain and lose energy, and also the state of comfort is satisfactory once all heat flow in and out of the body are in equilibrium. Also, (ASHRAE 2004), described it as “the state of mind that expresses satisfaction with the surrounding environment.” This definition highlights subjective and…

base assumption of the ‘Principle of Heat Exchange’, which is that the principle only holds true if heat is not lost to its surroundings. Although, the loss of heat to its environment (ex. Desk, air, cup, etc.) was attempted to be minimized by quick transfer of the water and object, and the use of a calorimeter, the data proves that there was a loss of heat as the theoretical temperature was higher than the resulting temperature. 2. For part two, compare your specific heat capacity value of the…

In 1996 Dolly the sheep was born. However, she was not born like most other sheep. Instead, Dolly was cloned from the DNA of an adult sheep. Although Dolly seemed healthy, she died in 2003 after being diagnosed with a progressive lung disease. Dolly was the only sheep out of 277 attempts that made it to a live birth. Would it be safe to take that chance when experimenting with cloning human babies? Some people seem to believe so, and agree with the idea of cloning to have a child. These people…

Although not as immediately critical as the availability of oxygen and glucose, it is important for the nervous system of ectothermic humans to maintain normothermia for effective cellular functioning (Morrison, 2011). The principle source of heat originates from the body. Temperature control mechanisms in humans consist of both core and peripheral processes. Responses elicited occur in a feed-forward manner. Changes in thermoreceptors in primary sensory nerve endings distributed to the skin are…

1. What factors should be considered to provide maximal protection when people are exercising in the cold? To avoid excessive heat loss, our bodies use peripheral vasoconstriction, nonshivering thermogenesis, and shivering, which is usually not enough. Peripheral vasoconstriction We must also rely on behavioral responses like huddling behavior and putting on more clothing to help insulate our deep body tissues from the environment. During aerobic exercise, clothing insulation and exercise…

Temperature is the measure of hotness expressed in terms of various arbitrary scales such as Fahrenheit, Celsius, and Kelvin. The Fahrenheit scale sets 32° as the freezing temperature for water and it assigns 212° the boiling point for water (What is Temperature, 2015) At the temperature of Absolute Zero there is no motion and no heat. Absolute Zero will occur when every atomic and molecular movement ceases and is at the lowest temperature possible. Absolute Zero on the scale is 0 degrees…

Did you know that "insulation reduces average home heating and cooling costs by around 20%". Many parts of the country have changed in temperature that affects the comfort in homes and workplaces. Season to season, these temperatures drive people crazy. In cold weather, this means it keeps the warm air inside and in the hot weather, it prevents hot air from coming in. Insulation helps maintain comfort no matter where you are. The best types would be the ones that keep the hot air out in the…

Considering A Whole-Home Evaporative Cooler? Know The Advantages And Disadvantages An evaporative cooling system will use air outside your home to cool the air inside your home by having it pass over a moistened pad. It can cool down your home from anywhere between 15-40°F, making it an acceptable way to keep your home cool in the summer. That said, the unit has its own advantages and disadvantages over central air conditioning. Consider the following things when researching a whole-home…

Background Research Focused, hard work is the real key to success. Keep your eyes on the goal, and just keep taking the next step towards completing it. If you aren't sure which way to do something, do it both ways and see which works better (John Carmack). The question, does the brand of insulation affect how cold the temperature is in a model house, is yet to be determined. The brand of insulations are, Green Fiber, Owens Corning, InsulFoam, and Johns Manville. The hypothesis is, If a model…
