Sample 1: In the weightless environment of the International Space Station, which of the following heat transfer mechanisms is less effective than in a similar room located at the surface of the Earth? a. Radiation b. Conduction c. Convection d. All of the above In the weightless environment, the less dense warm air will not tend to rise, inhibiting convection. Sample 2: How does the sun transfer energy to Saturn? a. Radiation b. Conduction c. Convection d. All of the above The answer is "Radiation". There is only empty space between the sun and Saturn, and radiation does not require a medium to transfer energy.
