1. The temperature inside a refrigerator is \(t_2\) °C and the room temperature is \(t_1\) °C. The amount of heat delivered to the room for each joule of electrical energy consumed ideally will be
(1). \(\frac{t_1}{t_1-t_2}\)
(2). \(\frac{t_1 + 273}{t_1-t_2}\)
(3). \(\frac{t_2 + 273}{t_1-t_2}\)
(4). \(\frac{t_1 + t_2}{t_1 + 273}\)
