If wet clothes are hung on the line to dry at 10 degrees fahrenheit on a sunny say in January, they will first become stiff and then eventually dry. The first process is called freezing. During the second process, called sublimation, ice goes directly to water vapor. Write the equations for these two changes which wter, H2O, undergoes. Indicate the state of products and reactants.
