What is the difference between alcoholic and Mercury thermometer based on their function? ​
user100 [1]
Alcohol filled thermometer is used for low temperature applications. (Weather) It’s freezing point is -70 degC
While mercury freezes at -38 deg C

Mercury is/was better for human and other animal temps. High thermal coefficient of expansion mercury vs. alcohol = better resolution for small temperature changes in a medical application.

For higher temperatures alcohol will boil before mercury will.

yan [13]

Translation of question

A ship is used to measure the depth of the sea using sound devices. A sound was fired at the bottom of the water and five seconds later there was a bounce. If the speed of sound in the water is 1500 m / s, then the depth of the water is

Answer:

3750 m

Explanation:

For sound to bounch back and be heard, this phenomenon is echo. Therefore, the distance traveled is 2d. Considering that speed is distance per unit time, expressed as s=d/t where d is distance, t is time and s is speed, in this case we say s=2d/t. Making d the subject of the formula then d=0.5st

Given 5 s as time and 1500 m/s as speed, we deduce that d=0.5*1500*5=3750 m
