What happens to specific range if temp rises

[verbc]

Thanks for the reply.

I got this question on my theoretical entry exam with Jetairfly. Next week I have been invited for the interview so I suppose I will be asked for an explanation.

So in response to your answer are this assumptions correct:

- higher temp means higher density thus less airframe drag and longer range
- higher temp means more thrust required thus more FF thus shorter range.

So which of the two is the limiting factor
