A & B are two identical thermometers but bulb of A is spherical & that of B is cylindrical. Which of the thermometers will show the temperature quickly?
Options:
Answer:
B
Solution:
For equal bulb volumes, a sphere has the least surface area.
The cylindrical bulb exposes more area to heat exchange.
With otherwise identical thermometers, B reaches the measured temperature faster.
