Question 49

A thermometer is calibrated in degrees Celsius, with scale markings ranging from −20∘C-20^\circ\text{C}−20∘C to 120∘C120^\circ\text{C}120∘C.

What are the values of the lower fixed point and of the upper fixed point on the Celsius scale?

A

Lower fixed point = −20∘C-20^\circ\text{C}−20∘C, Upper fixed point = 120∘C120^\circ\text{C}120∘C

B

Lower fixed point = 0∘C0^\circ\text{C}0∘C, Upper fixed point = 100∘C100^\circ\text{C}100∘C

C

Lower fixed point = 0∘C0^\circ\text{C}0∘C, Upper fixed point = 120∘C120^\circ\text{C}120∘C

D

Lower fixed point = −20∘C-20^\circ\text{C}−20∘C, Upper fixed point = 100∘C100^\circ\text{C}100∘C
