Calculate the amount of heat released (in kJ) when 50.0 g of the fluorocarbon C₂C13F3 are cooled from 80.0°C to 5.0 °C. Make sure you include the correct sign as part of your answer. prie
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.
Cooling curve is basically a diagram of state and phase transformation of any substance with respect to temperature. It means cooling curve explains how phase or state of any substance changes when temperature is increased or decreased.
At boiling point and melting point substance changes their phase.
Boiling point = 47.6 °C
Melting point = -36.4 °C
