The first law of thermodynamics states that when a process converts energy from one form to another, some energy converted into heat, an unusable form of energy energy can neither be created nor destroyed, but it can change from one form to another energy flows through ecosystems without being recycled most energy in ecosystems comes from the sun

Tungsten-filament lightbulb emits light based on the temperature of the filament. which phenomenon does this demonstrate?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

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.
