1.	A body having `110 and70^(@)C` temperatures of surrounding and of itself repectively . What would be the value of coefficient of performance ?A. 1.75B. 2.3C. `1.50`D. 2.55
Answer» Correct Answer - A Given , `T_(1)=110^(@)C,andT_(2)=70^(@)C,beta` = ? Coefficient of performance `beta=(T_(2))/(T_(1)_T_(2))=(70)/(110-70)=(70)/(40)=1.75`
