A very thin-walled spherical storage tank has an outer diameter of 26 cm. The inner surface temperature of the tank is 413K. The spherical tank was covered with three insulation layers, and each insulation layer is 50 mm thick. These layers' thermal conductivities are 0.02, 0.06, and 0.16 W/m. K (i. e., starting from inside). The layer's outside surface temperature is 303 K. Calculate the heat transfer rate and the interface temperatures of insulating layers

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

the ratio of the conjugate base to the acid required to attain the desired ph.
