- An energy interaction is heat transfer if its driving force is a _______ difference. A: density B: pressure C: volume D: temperature
- The main reason why air-conditioner indoor machines can have multiple colors is A: The difference in emissivity of different colors paints at room temperature is small B: The emissivity of different colors paints varies greatly at room temperature C: The absorptance of different colors paints to visible light is quite different at room temperature D: The difference in the absorptance of different colors paint to visible light at room temperature is small
- Same goods can be valued different at different times. Goods often stop during the transfer process, which is professionally called the ().
- As the temperature of a body rises, the radiated heat also increases.
