why is mercury used in thermameter?and what is the difference between the clinical and the lab thermameter?
Mercury is used in thermometers with a higher range, as its freezing and boiling points are -39c and 360c while alcohol is used in those needing to measure a lower range with -114c and 78c respectively.
Mercury is used in thermometers becuase it expands easily and does not stick to the sides of the thermometer. Difference between clinical and lab thermometer- The range of clinical thermo.is between 35 degree celsius to 42degree celsius whereas the range of lab. thermo. is between -10degree celsius to 110degree celsius. CT are used to measure temp. of human body whereas LT is used to measure the temp. of objects other than the human body.

Tank A contains 5 times as much water as Tank B. How much water must Gautam transfer from Tank A to Tank B so that each tank contains 45 litres of water ?PLEASE EXPLAIN IN DETAIL! (A)30 litres (B)60 litres (C)75 litres (D)90 litres
The answer is 30 litres(a). Tank A: 45+30=75 Tank B:75/5=15 so the water transferred from Tank A to tank B so that each tank contains 45lit of water should be 30 litres [Tank A: 75-30=45; Tank B: 15+30=45]
