This document contains a Spanish language exam on physics and chemistry concepts related to matter and energy. It consists of 7 multiple choice questions testing understanding of states of matter, phase changes, density, kinetic energy, and the relationship between temperature and particle motion. The questions assess knowledge of key terms like solid, liquid, gas, condensation, vaporization, kinetic energy, boiling point, and how properties change during phase transitions.
