We discussed earlier some basic principles about the behavior of gases called the kinetic-molecular theory. Among other things, this theory suggests that gas molecules are in constant motion, and the average speed of the individual gas particles is dependent upon temperature – the higher the temperature, the faster the molecules move. It is not just gas particles that are in constant motion. The molecules and ions that make up liquids and solutions are also continually moving in nearly random directions. As a result, molecules and ions in a solution will collide with one another fairly frequently. As with gases, a temperature increase will produce an increase in the average particle speed.
Beth grabbed her container of chili from he fridge and tossed in the microwave for 4 minutes. However, she forgot to vent the lid and after several minutes the dish exploded spraying chili all over the inside of the microwave.
Was the temperature of the liqued increasing or staying constant?
