Decreases because the lower the temperature the less active the particles are
i think you should multiply them, the speed is 12 * 3 = 36 m/s
Answer:
Via, vibration.
Source generate vibration, and air molecules vibrate, so kinetics and potential energy transfer
Answer:
All objects emit and absorb infrared radiation. The hotter an object is the more energy it radiates per second. Infrared radiation can travel through a vacuum. When infrared radiation hits an object some of the energy is absorbed, making the objects temperature increase, and some is reflected.
