Here are the answers to [[2021-2022 Energy and Math Review Homework]].<br> <br> 1) System is the substance(s) that is going thru the change. The surrounding is everything else in the Universe.<br> <br> 2) Heat is a form of Energy. Unit of energy is Joules, BTU and calories.<br> <br> 3) Minimum amount of energy needed for a set of reactants to form a set of products.<br> <br> 4) Greater than<br> <br> 5) Temperature<br> <br> 6) Energy flow from a high temperature body to a lower temperature body until the temperatures are equal.<br> <br> 7) there is no energy, 0K (no movement energy), pure crystal/substance (no Entropy energy)<br> <br> 8) randomness or disorder<br> <br> 9) releases<br> <br> 10) If you do not have a Perfect crystal, then there is randomness in the system (which requires energy).<b>THIS QUESTION IS NOT ON TEST</b><br> <br> 11) Relative temperature scale are based on a condition that can change (FP/BP of water) <br> <br> 12) Kelvin by 273<br> <br> 13) 293K for 20.°C (298K if 25°C)<br> <br> 14) Disagree since the energy is not LOST but just moved from the chemical reaction to the surroundings.<br> <br> 15) When all the reactants are together (including all PE reactant and Activated energy) just before they reorganize into the products.<br> <br> 15) Enthalpy is the energy that holds the substance together (example bonds), energy of movement (called Temp) and energy in the phase of the substance.<br> <br> 16) Will talk about in class.
