Suppose that 1.15 g of rubbing alcohol (propan-2-ol) evaporates from a 65.0 g aluminum block. If the block is initially at 25°C, what is the final temperature of the block after the evaporation of the alcohol? (Assume that the heat required for the vaporization of the alcohol comes only from the aluminum block and that alcohol vaporizes at 25°C, aluminum’s specific heat capacity (Cs) is 0.903 J/°C.g)
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.
Suppose that 1.15 g of rubbing alcohol (propan-2-ol) evaporates from a 65.0 g aluminum
block. If the block is initially at 25°C, what is the final temperature of the block after the
evaporation of the alcohol? (Assume that the heat required for the vaporization of the alcohol
comes only from the aluminum block and that alcohol vaporizes at 25°C, aluminum’s specific
heat capacity (Cs) is 0.903 J/°C.g)
