A XY kg block of iron casting at 450 K is thrown into a large lake that is at a temperature of 200 K. The iron block eventually reaches thermal equilibrium with the lake water. Assuming an average specific heat of 0.50 kJ/kg. K for the iron, determine (a) the entropy change of the iron block, (b) the entropy change of the lake water, and (c) the entropy generated during this process.

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer

True is ur answer : )

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.

Green is technically every other color but green but the other wavelengths of the other colors get absorbed by the object and the wavelength of the color green gets reflected
