Termometría. Las temperaturas iniciales de m gramos del líquido A, 2m gramos del líquido B y 3m gramos del líquido C son respectivamente 30° C, 20°C y 10°C; mezclando los líquidos A y B la temperatura final es 25°C; mezclando los líquidos B y C, la temperatura final es 14,5°C. ¿Cuál será la temperatura final si se mezclan los líquidos A y C? Desprecia la capacidad calorífica del calorímetro y supóngase que no hay reacciones químicas durante la mezcla de líquidos.

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
