Asolar water heater consists of a flat plate collector that is coupled to a storage tank. the collector system is as shown in pr.9.100 in the textbook, page 615. consider a collector that is 1.5 m high and 3 m wide solar collector, the back side of the collector is insulated. the absorber plate and the glass cover are spaced 5 cm from each other, are maintained at temperature of 80°c and 40°c, respectively: a) draw the schematic of the system. b) determine rate of heat transfer by convection from the absorber plate for bl ) vertical solar collector at-90° b2) tilted solar collector at t -35 b3) tilted solar collector at t-4 b4) write your comments it is recommended to construct an excel program to solve pr.5 pr.6 (30 points) a house roof (5m x 5m), inclined at an angle of 27o to the horizontal, and has an outside surface temperature of 30°c while the outside air is at 40°c: a) draw the schematic of the system. bcalculate the heat transfer coefficient between the roof

to make a supersaturated solution, make a saturated solution of sugar by adding 360 grams of sugar to 100 ml of water at 80 degrees celsius. when the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water should only dissolve 210 grams of sugar.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
