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.
Determine the amount of heat, in kJ, required to heat 100.0 g of liquid Ca at 851C to 951C.
Melting Point = 851C Boiling Point = 1487C
Molar Heat Capacities
C = 26.2 J/molC
C = 31.0 J/molC
ΔH = 9.33 kJ/mol
ΔH = 162 kJ/mol
