The planets mars and venus have albedo values of 0.15 and 0.75, and observed surface temperatures of approximately 220 k and approximately 700 k, respectively. the average distance of mars from the sun is 2.28 × 108 km, and the average distance of venus is 1.08 × 108 km. what is the extent of the greenhouse effect for these two planets, measured in degrees kelvin?

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.

What is a monomer? how do they form a ploymer from the view point of chemical bonding?

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
