A thermometer is constructed by filling a small glass tube with a liquid that expands linearly with temperature.The thermometer is then calibrated at 0S1U1P1$\circ$S1S1P0C and 100S1U1P1$\circ$S1S1P0C,and the scale evenly divided between the two values.Unfortunately a manufacturing defect results in the middle one-third of the tube being narrower,otherwise the tube has uniform diameter.For what range of temperatures is the reading accurate?
