Question

what state of matter is a sample at 1.0 atm and 85 °c? chart of pressure (atm) vs temperature (°c) with solid, liquid, gas regions options: gas, liquid, solid

Explanation:

Step1: Locate the point on the phase diagram

Find the intersection of pressure = 1.0 atm and temperature = 85 °C on the given phase diagram.

Step2: Identify the phase region

Check which phase region the intersection point lies in. The point at 1.0 atm and 85 °C is within the liquid region.

Answer:

liquid
