1.	41. In a closed insulated container, a liquid isstirred with a paddle to increase thetemperature. Which of the the following istrue?1) AU =W 0,q=0 2) AU =W = 0,9 303) AU = 0,W = q +0 4) W = 0, AU = q = 0please give me reply it's urgent
Answer» In closed insulated container a liquid is stirred with a paddle to INCREASE the temperature, THEREFORE, it behaves as an adiabatic process, q=0. HENCE, from the first law of thermodynamics: ΔE=q+W; ∵q=0 ΔE=W but not EQUAL to zero. Hence, the correct answer is option B.
