HEAT ENGINE WORKING CYCLES An engine is a device which transforms one form of energy into another form. However‚ while transforming energy from one form to another form‚ the efficiency of conversion plays an important role. Normally‚ most of the engines convert thermal energy to mechanical work and therefore they are called ‘heat engines’. Heat engine is a device which transforms the chemical energy of a fuel into thermal energy and utilizes this thermal energy to perform useful work. Depending

As Canadians‚ we love the summer heat. We bask in it. We frolic in it. Then‚ we complain about it. It’s true. However‚ this week‚ every single complaint made about the weather is warranted because this heat wave is downright ridiculous. Ridiculous! With that being said‚ raise your hand if you leave your home in the morning with perfect make-up and five minutes later‚ you resemble a female version of Alice Cooper. You and me both. Don’t worry – we have you covered with these 5 simple steps on how

based upon an energy analysis that takes into account all the modes of energy loss (L) from the body‚ including: the convection and radiant heat loss from the outer surface of the clothing‚ the heat loss by water vapour diffusion through the skin‚ the heat loss by evaporation of sweat from the skin surface‚ the latent and dry respiration heat loss and the heat transfer from the skin to the outer surface of the clothing. The model assumes that the person is thermally at steady state with his environment

Heat exhaustion: This condition often occurs when people exercise in a hot‚ humid place and body fluids are lost through sweating‚ causing dehydration and overheating of the body. Temperature may be elevated‚ but not above 104 F (40 C). Occurs when not well adjusted to heat exercise. At high temperatures‚ the body cools itself largely through evaporation of sweat. When humid‚ this mechanism does not work properly. Body loses a electrolytes. When this is accompanied by an inadequate replacement of

Effect of Heat on Vitamin C Objective: - To determine whether the concentration of Vitamin C in a fruit juice changes upon heating at a constant temperature for different periods of time. - To investigate how the trend goes (whether the concentration of Vitamin C increases or decreases) if the amount of Vitamin C does change. Theory: - Hypothesis: The concentration of Vitamin C in the fruit juice changes and decreases upon heatingat a constant temperature for increasing periods of time
