Asphere is assumed to have the properties of water and has an initial heat generation 46480 w/m^3 how much should the heat generation term be lowered, if the maximum temperature at the center of the spherical geometry is to be limited to 360 kelvin? the radius of the sphere is 0.1m ambient air temperature is 25 c. convert the resulting heat generation to food calories per hour

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
