How many grams of coffee must evaporate from 800 g of coffee in a 180 g glass cup to cool the coffee from 95.0°C to 39.0°C? You may assume the coffee has the same thermal properties as water and that the average heat of vaporization is 2340 kJ/kg (560 cal/g). (You may neglect the change in mass of the coffee as it cools, which will give you an answer that is slightly larger than correct.) g

Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.

How many grams of coffee must evaporate from 800 g of coffee in a 180 g
glass cup to cool the coffee from 95.0°C to 39.0°C? You may assume the
coffee has the same thermal properties as water and that the average heat
of vaporization is 2340 kJ/kg (560 cal/g). (You may neglect the change in
mass of the coffee as it cools, which will give you an answer that is slightly
larger than correct.)
