If the mass of the apple is 0.1515 kg, find the apple volume (cm3) and apple density (g/cm3). Is the calculated density, the true density or bulk density? Is the provided density for canola seeds a bulk or true density?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
The powder (using canola seeds) displacement method was used to determine the volume of an apple at room temperature (25.0ºC). The container was filled with canola seeds and mass was determined to be 1684.4 g. The container was emptied, the apple was placed into the container, and then the container was filled with canola seeds and the mass was 1701.9 g. The density of canola seeds is 0.6580 g/cm3.
