Answer:
1.
Radiant heating and cooling systems are temperature-controlled surfaces that exchange heat with their surrounding environment through convection and radiation. By definition, in radiant heating and cooling systems, thermal radiation covers more than 50% of heat exchange within the space.
2. the process in which heat moves through a gas or a liquid as the hottest part rises and the cooler heavier part sink
