Chapter 1, Problem 1.113E

A new linear temperature scale, degrees Zunzol (°Z), is based on the freezing point and boiling point of a newly discovered compound zunzol. The freezing point of zunzol, -141.5 °C, is defined as 0 °Z, and the boiling point of zunzol, -24.8 °C, is defined as 100 °Z. What is the freezing point of water in degrees Zunzol? freezing point: Z. What is the boiling point of water in degrees Zunzol? boiling point: I. Z. TOOLS X10 64°F Clear 2:10 PM JENG 9/3/2021 F4 FZ F8 home end nser t delete 12
