Placing an inflated balloon in the freezer would result in which of the following?
Correct Answer: D.the kinetic energy of the gas particles would decrease
If the balloon is placed in the freezer, the particles lose kinetic energy as the gas particles slow down and have fewer collisions with each other and the container. As a result, if the internal collisions between the gas particles and the inside of the balloon decrease, the volume of the balloon would also decrease and eventually the balloon would deflate. This is a prime example of Charles’ Law.
The Dental Admission Test (DAT) is a test administered by the American Dental Association (ADA). The test is four hours and 30 minutes long and contains four sections. The test is designed to assess your knowledge in: biology, chemistry, organic chemistry, perceptual ability, reading comprehension, and basic math.
How Should I Study?
The DAT is the final challenge before you apply to dental school and should not be taken lightly. Depending on the strength of your scientific knowledge, your study schedule should be between 4 to 10 weeks. Here's a link to my definitive DAT study guide and schedule which will help you prepare.
Register for the DAT.
You should plan on taking the DAT late spring or during the summer of your application year. For example, the class of 2020 should take the DAT in the spring or summer of 2015. You can begin the registration process for the DAT at the ADA's website. Be sure to apply for a test date early as the registration process may take some time.
