Which of the following statements are IMPOSSIBLE? Choose all that apply. A. The temperatureinside a vacuum chamber was measured to be -17°C. B. During anadiabatic process, 48 J of heat was absorbed by thesystem C. During anisothermal process, the temperature decreased D. Last Wednesday,the Sun heated the Moon via convection E. A 16 Lcontainer (that was fully submerged in mercury) displaced 17 L ofmercury F. In water, softsounds travel slower than loud sounds Which of the following statements are IMPOSSIBLE?

Explanation / Answer

Impossible statements are: B. adiabatic process means there's no heat absorbed or emitted C. isothermal means the temperature is kept constant D. convection can't take place in the vacuum between the Sun andthe Moon E. Of course this is impossible because the container can notexpand to 17L anyway F. The speed of sound doesn't depend on the frequency of sound,hence the 2 sounds above have the same speed
