Homework Statement
1. A kettle holding 1 lt. of water is boiling. Assuming water is evaporating at a constant evaporation rate of 1g/min, determine how long it will take for the kettle to dry out.
2. Another kettle holding 1 lt. of water and 20g of salt is also boiling. Again water evaporates at a rate of 1g/min. This time you are asked to derive a mathematical relationship for how salt concentration in the kettle changes with respect to time.
