Answer should be 2 as heat potential has to be equal.

the answer should be object 2 , as object 1 has negative temperature ie. -1,-2,-5,.....-100 etc . but a positive object will have positive temperature , like 1,2,3,...100..etc. so when asked who's gonna loose heat , then it's object 2 .

The answer is indeed Object 1 (negative temperature object is hotter than positive temperature object). This is not a level 1 question.

Can you explain what is negative temperature and what is positive temperature

The correct answer is 2 since heat flows from hot to cold object.Hence 2 will loose n 1 will gain heat.

If you will apply this concept in IIT-JEE, you will definitely qualify. (pun intended)

Negative Kelvin???

I think heat flow from higher to lower temperature so correct answer must be object 2.

I mean, yes, it is theoretically possible, but...
