A new linear temperature scale, degrees Zunzol (${}^{\circ }\text{Z}$), is based on the freezing point and boiling point of a newly discovered compound zunzol. The freezing point of zunzol, $-22.9{}^{\circ }\text{C,}$ is defined as $0{}^{\circ }\text{Z,}$ and the boiling point of zunzol, $79.8{}^{\circ }\text{C,}$ is defined as $100{}^{\circ }\text{Z.}$ What is the freezing point of water in degrees Zunzol? What is the boiling point of water in degrees Zunzol?
