The temperature inside a refrigerator is t₂ ^oC. The amount of heat delivered to the room for each joule of electrical energy consumed ideally will be

$${{{t_1}} \over {{t_1} - {t_2}}}$$

$${{{t_1} + 273} \over {{t_1} - {t_2}}}$$

$${{{t_2} + 273} \over {{t_1} - {t_2}}}$$

$${{{t_1} + {t_2}} \over {{t_1} + 273}}$$
