What does the diagram show about phases and the phase of the substance as it is heated? Check all that apply. The substance is a gas at more than 2,000°C.

The particles are close together but move in different directions between 0°C and 2,200°C.

The attractions between the particles increase in region 2.

The speed of the particles increases in region 5.

The substance does not exist as a solid.

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.
