Exception in thread main java.lang.NullPointerException is one of the common problems and Java error that you will face when developing pure Java or Java EE applications.This Java Exception has been around since early JDK days e.g. JDK 1.0.his is critical data since it allows you to trace back the problem in your application Java code at this particular line of code of the affected Java class. java.lang.NullPointerException: Resolution strategies. Now that you understand this problem, it is now time to resolve it.
Key Concepts. 1  Condensation is the process in which molecules of a gas slow down, come together, and form a liquid. 2  When gas molecules transfer their energy to something cooler, they slow down and their attractions cause them to bond to become a liquid. 3  Making water vapor colder increases the rate of condensation.ut as the concentration of water molecules increases in the container, the rate of condensation increases. Eventually, the rate of condensation equals the rate of evaporation and the water molecules go back and forth between the liquid and the gas.
A: There are quite a few things which affect how fast water vapor will condense, more than the ones you mention. It takes 540 calories per gram of water to make it turn into vapor. The water releases this same amount when it condenses.
