Will an empty balloon have precisely the same apparent weight on a scale as a balloon filled with air? Explain

Rino wants a high speed of water when it flows out from his pipe. The rate of water flows from his pipe now is about 10 m/s. (i) If he wants the rate of water flows two times from his rate of water flows now, determine the diameter of the other end of the pipe should he changes. Given the radius of his pipe is 2.0 m. (ii) With the fast rate of water flows that he has now, determine the volume of water that he can have in 10 minutes.

The vapor pressures of a halogen compound in its solid and liquid phases display the following temperature dependence: p(s) 4012 K T solid- liquid- In 1 bar (1) P 1 bar 18.316- = 11.247- 2589 K T where T is in K. (a) Determine the temperature of the triple point (in K).

Consider the air and the bell jar. After the syringe has been pumped, the volume of air in the jar (increase,decrease or remains the same) the pressure (increase, decrease or remains the same) and the density (increase, decrease or remains the same).
