Student X decided to perform a science experiment, where she wanted to determine the pressure within the classroom. She took a balloon and inflated it to 1.50 L (at 19oC), and then heated up the balloon to 22oC. The balloon grew to a size of 1.9 L after being heated. When released outside, the pressure in the balloon was 103 kPa. What was the original pressure of the balloon, when still inside? Show all work (Formal method)

Serious injuries can occur when students attempt to force the pipet bulb onto the top of the pipet. The blue bulbs we use in lab are not meant to attach to the pipet, they simply rest on the top. Which of the following items will help you be more successful when working with a pipet? Group of answer choices Gently place the pipet bulb on the pipet Keep the tip of the pipet submerged when filling It is best to fill the pipet to a point just above the calibration line, then adjust the volume by slowly releasing liquid. Liquid should fully fill the pipet bulb The more aggressive you are with the pipet bulb, the quicker you will get out of lab
