Will a hot air balloon still rise if the surrounding air is the same temperature

if the air temperature outside of the hot air balloon and the air inside the hot air balloon are the same, will that balloon still rise or just remain at the same point. This is not to say both temperatures are cold. Both temps should be hot. Hot enough for the air to rise, but if the outside and inside are equal in the heat, will that big a/s/s balloon move or just stay in the same spot. I think this would be difficult to try because a hot air balloon is very large and to heat all the surronding air around it might be next to impossible. This only applies to hot air. Not other types of gasses lighter than air, were temp wont affect lift dramatically. The reasonig for this question is for exploration on other planets with hot air temps, would this type of situation work using only air? And would it be possible to control it?
