3.1.1 KMT & States of Matter Unit Assessment

Minnesota State Standard 9C.2.1.4.1 Use kinetic molecular theory to explain how changes in energy content affect the state of matter (solid, liquid and gaseous phases).

Learning Target 3.1.1: I can define the kinetic molecular theory and apply it to various states of matter.

Goal 3.1.1.a I can recall that matter is made of tiny particles that are in constant motion.

Goal 3.1.1.b I can compare the motion of these tiny particles in solid and liquid states of matter.

Goal 3.1.1.c I can compare the motion of these tiny particles in gaseous states of matter.

Goal 3.1.1.d I understand the transitions from one state to another in terms of energy absorbed/released.

Essay Question:
A 10.0 g sample of lauric acid solid pieces is scooped into a glass test tube. The melting point of lauric acid is 44°C and the boiling point of lauric acid is 298°C. Explain the motion of the particles and the states of matter as energy is added to the system and the temperature goes from 18°C to 320°C. You should use the kinetic theory of matter in your explanation.
