The first instrument we will use in lab is called a graduated cylinder. A graduated cylinder reads starting from zero at the bottom and goes up as liquid fills it. Keep in mind that you should always estimate one digit further than what is marked on the device to preserve your significant figures. For example, if the device has 1.0 mL increments, the measurement can be estimated to the second decimal place. For the graduated cylinder below, what would be the correct volume reading considering that the markings are in milliliters? Hint: What are the increments of measurement on the graduate cylinder below? -60 -50 -40 -30 -20

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
