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.

Question

C) Less than 100 °C because as the water gets hotter, it takes a greater amount of heat to
raise the temperature by one degree.
D) 100 °C because that's the highest temperature liquid water can reach at 1 atm pressure.
E) The water will all boil away before that much heat can be added.

8. 1026 kJ of heat is added to a sample of water at 1 atm pressure and the temperature rises
from 40 °C to 80 °C. If 1026 kJ more heat is added, what will the final temperature of the
water be?
A) 120 °C because the water will continue to heat up at the same rate.
B) More than 100 °C but less than 120 °C because some of the heat will be used to
boil the water.
