Which statement about the properties of matter is true? *25*

a. it is possible for matter to have different physical properties but the same
chemical properties.
b. it is possible for matter to have only chemical properties.
c. it is possible for matter to have many chemical properties that depend on the
state of matter.
d. it is possible for matter to have no chemical properties.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
