alwys take temperature in kelvin, but here in the solution, u need temperature difference (T1-T2) so temperature difference is same in Celsius or in kelvin.. so no need to worry, i...
Very Important : The formula for efficiency = (1-T2/T1) is only applicable in Kelvin units!! Yes, you have pointed out a valid doubt. But in the solution above, we need temperatur...
it actually doesn't matter even if we keep temp in Kelvin or celsius here as far as the temp diffenrce is concerned and the temp diffenrce remains same ( 50+ 273 - (10+273) ,so we ...
