Sea surface temperature

Scanning electron microscope (SEM, Quanta 250 FEG, FEI Company, USA) at an accelerating voltage of 30 kV was used for evaluation of surface morphology and particle size determination. The specific surface area of the HAPNRs was measured by the BET-method (adsorption gas N2, carrier…

heat flux emitted by the sky on the transparent glass cover (W), it is given by the following equation: The radiation transfer heat coefficient between the transparent glass cover and the sky is calculated by the following equation [40]: The sky temperature could be determined by Swinbank equation [41]: QGround_G: The radiation heat transfer emitted by the ground on the transparent glass cover (W), is given by the…

lost by drift is negligible. • Water temperature is uniform at each section of the tower. • Cross-sectional area of tower is constant Mathematical equations Consider a counter-current cooling…

The story begins when the man wants to take a journey to the boys that are prospecting for gold. However, his arrogant prevents him from listening to the old-timer from Sulphur Creek who warned him about the danger of traveling alone when the temperature is below fifty degrees and he started his journey alone in sub-freezing weather. Throughout the story, and through his journey, the man learned a lot of new things and went through many obstacles, also he got accompanied with a husky dog.…

through the ice and his feet get wet and needs to build a fire he is determined to start one and keeps trying over and over again. The man is also “intellectual” by how he uses more advanced technologies like matches and how he knows the temperature through temperature readings (gradesaver.com). But as the reader finds out as they read the man is cocky and thinks he knows everything he needs to know to survive. When the man is freezing to death and unable to start a fire he even tried to kill…

Resistors can also be used to provide a specific voltage for an active device such as a transistor. For a fixed temperature, the current flowing through a resistor is directly proportional to the voltage across the resistor. Formula to work out resistance is Voltage (V) = Current(I) × Resistance (R) and the SI unit is Ohms (Ω). Inside the resistor there is an insulting…

effect of temperature, time and current density on surface roughness in electropolishing process on 316L stainless steel. The cathode material under study was 316L stainless steel. The electrolyte was composed of sulfuric acid, phosphoric acid, and DI water. Full factorial design method was used. ANNOVA technique has been used to assess the quantitative influence of the different process factors of the EP. The surface roughness will be obtained up to 0.03 µm in this experiment whose surface…

Have you ever wondered what it is like to travel in extremely cold temperatures on a gray, cold, Yukon Trail, at nine o’ clock at night, just you and your dog? In the short story To Build a Fire that could give you a glimpse of it would be like. To Build a Fire is a story of a man’s incapability of attempting to travels through ten rough miles of Yukon Wilderness in the Yukon Trail in Alaska. Not only is this place beyond freezing, but it is exactly 75 degrees below zero. The man has his route…

Introduction In this experiment, isopentyl acetate was prepared by the direct esterification of acetic acid with isopentyl alcohol, which is an equilibrium that results in a shift in favor of the product by using one of the starting materials in excess. An esterification reaction is when an acid is converted into an ester by combining with an alcohol and removing a water molecule. Esters are found in numerous natural products, including fruits, flowers, and spices. Carboxyllic esters contribute…

science fair project is questioning whether or not mints really make one's mouth cold. To test this the theory, the project will include a glass of lukewarm with mints added in every few minutes. How will adding mints in a glass of room temperature water affect the temperature of water? Why does it feel like mints cool down one's mouth? According to David McKemy, a neurobiologist at USC Dornsife, a protein called TRPM8 that is found in all cold sensing nerve fibers that triggers an electrical…
