A wrongly calibrated uniform-capillary thermometer reads ice melting as -10°C and reads 60°C at a true temperature of 50°C. Its reading at the boiling point of water is:

Options:

Answer:

Solution:

Let $r = a C + b$ . Ice gives $b = - 10; 60 = 50 a - 10$ gives $a = 1.4$ . At $10 0^{\circ} C, r = 140 - 10 = 13 0^{\circ}$ .
