Hello. I tried in google but i haven't found what i had been looking for. My question is simple. Take this example. A containter insulated from external enivironment has a hot gas inside it. This gas tank is located in empty space of universe at 1K. How long does it takes the gas to cool till temperature of the empty space? Which is the best grade of insulation for a tank in space,like shuttle or ISS? Which percentage of heat go lost?
Thanks
