Gas Laws. Learning Objectives TLW know the variables that influence the behavior of gases (TEKS 9) TLW be able to describe interrelationships between.
GAS LAWS!. COMPRESSIBILITY Compressibility is a measure of how much the VOLUME of matter can DECREASE under pressure.
What is a Mole Chemists use the mole to count microscopic particles. How many socks come in a pair? 2 How many eggs are in a dozen? 12 How many eggs come.
