Elaborate on the reason why heating water up will increase the rate of dissolving for a solute. a) the average kinetic energy of the solute molecules decreases with increasing temperature, and it changes the state of dissolution. the increased movement of the solute molecules causes them to break, and thus they dissolve more readily. b) the molecules that make up the solution speed up with increasing temperature. this increase in kinetic energy allows the solvent molecules to more effectively hold themselves together and strengthen the intermolecular attractions between solute molecules. c) the average kinetic energy of the solute molecules also increases with temperature, and it destabilizes the solid state. the increased vibration (kinetic energy) of the solute molecules causes them to hold together better, and thus they dissolve more readily. d) the average kinetic energy of the molecules that make up the solution also increases with increasing temperature. this increase in kinetic energy allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

The inside surface of a cylindrical-shaped cave of inner diameter 1.0 m is continuously covered with a very thin layer of water. the cave is very long and it is open on both ends. the water on the cave surface is at a constant temperature of 15.5 °c. the cave is constantly exposed to wind such that 15.5 °c air flows through the cave at 4.5 m/s. the kinematic viscosity of the air is 14.66 x 10-6 m2/s and the molecular diffusion coefficient of water vapor in the air is 0.239 x 10-4 m2/s. because the cave diameter is so large, the flow of wind down the length of the cave, in the x direction, can be treated like it is external flow and the cave surface can be approximated as flat where appropriate. calculate the x value, in a) the transition to turbulent flow occurs at rex meters, where the air flow transitions from laminar to turbulent along the inside surface of the cave b) calculate the x value, in meters, where the bulk steady state concentration of water vapor in the air flowing in the cave is 10% of the saturation concentration. assume the air at the surface of the water layer is 100% saturated with water vapor. assume the wind entering the cave contained no moisture before it entered the cave. take into account the transition from laminar to turbulent flow when solving part b
