Mercury and Alcohol are two common liquids used in thermometers. The boiling point of MERCURY is 357 degree C, while its freezing point is -39 degree C; For ALCOHOL, the boiling point is 78 degree C and the freezing point is -80 degree C; It is required in a laboratory to make measurements which are in the region of -60 degree C. Which type of thermometer would be more suitable? (ASSET)

Alcohol

Step-by-step explanation:

Alcohol would be more suitable for making measurements in a -60 degree laboratory, since its boiling point is 78 degrees and its freezing point is -80 degrees, meaning alcohol will not freeze in a -60 degree environment.

Mercury on the other hand, has a freezing point of -39. Thus, it will freeze in a -60 degree environment, making it not suitable for use in this laboratory.

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
