Question and answer
7. Calculate the maximum possible efficiency of a power plant that burns natural gas at a temperature of 600 K, with low-temperature surroundings of 300 K. How much more efficient would the plant be if it were built in the Artic where the low-temperature reservoir is at 250 K? Why don’t we build all power plants in the Artic?

Weegy: efficiency (percent) (temperature HOT minus temperature COLD) - - - - - - - - - - - - - - - - - - X100 temperature HOT (600-300)X100 - - - - - - - [ 600 600-300=300 300 divide by 600=0.5 0.5x100= 50% ]

It's more efficient to burn fossil fuels to supply heat than to generate electricity because: The efficiency of heat production is much higher than performing work.
