5) How much heat is required to warm 1.50 L of water from 25.0 °C to 100 °C? (Density of water = 1,0 g/mL for the water; Cs of water 4.18 J/g oC). Evaporating sweat cools the body because evaporation is an endothermic process which can be expressed using the following reaction: H20 (g) AHOxn +44.01 kJ H2O (I) Estimate the mass of water that must evaporate from the skin to cool the body by 0.5 °C. Assume a body...

Exercise 5: I was changing 34 around too much that I just made it a separate exercise. Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice at - 8.5C is taken from a freezer and added to the alcohol in the cup. The final temperature of all the components is 18.0C. Assuming no heat was lost from the system, calculate the mass m...

QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...

a) (15 p) We consider a nuclear reactor of power output P=1000 Megawatt (1000 million watts) electric, functioning with Plutonium. It is fueled, initially, with 1000 kg of Plutonium. The nuclear material in question is made of Plutonium nuclei, each 239 consisting in 94 protons and 239-94-145 neutrons, which is denominated by the symbol 94Pu. For thermodynamical rd reasons, only 1/3 of the nuclear energy in the form of heat produced by the reactor, can be converted into electricity. How...
