Initially (state 1) a well-insulated rigid tank contains 11 kg of a saturated liquid-vapor mixture of water at 100 kPa and half of the mass is in the liquid phase. An electric resistance heater placed in the tank is now turned on and kept on until all the liquid in the tank is vaporized (state 2). Determine (a) the initial specific volume in m3/kg, (b) the final specific entropy in kJ/kg. K and (c) change of entropy in kJ/K.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
