Thermal properties and temperature — practice question

A thermometer is marked with graduations beginning at $-10\,^\circ\text{C}$ and finishing at $110\,^\circ\text{C}$. What are the lower fixed point and the upper fixed point of the Celsius scale?

  • Alower fixed point $-10\,^\circ\text{C}$; upper fixed point $100\,^\circ\text{C}$
  • Blower fixed point $-10\,^\circ\text{C}$; upper fixed point $110\,^\circ\text{C}$
  • Clower fixed point $0\,^\circ\text{C}$; upper fixed point $100\,^\circ\text{C}$
  • Dlower fixed point $0\,^\circ\text{C}$; upper fixed point $110\,^\circ\text{C}$
