Greetings Stovers, Wanting to know if it takes less energy to keep water boiling at 80 deg. C at 1500 meters than at sea level? Also; It take 4.186 j/g/deg.C to raise water from 20c to 80c at sea level. But is it the same at 1500 meters? or is it less than 4.186? Thanks for any understanding help Frank Frank Shields
