The solubility of solids_and the solubility of gases _ with increases
in temperature.
A. increases, increases
B. increases, decreases
C. decreases, decreases
D. decreases, increases

the correct answer would be d. hope this !

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

ok whats the question if not i cannot you i need question and need a thing to answer
