Why is the second law of thermodynamics not violated by living organisms? |
|
Answer» The second law of thermodynamics STATES that the entropy of a closed system will always increase with time. The only KNOWN closed system is the entire UNIVERSE. Living organisms are not a closed system, and THEREFORE the energy input and output of an organism is not RELEVANT to the second law of thermodynamics. |

What does the second law of thermodynamics state quizlet? |
|
Answer» The SECOND LAW of thermodynamics states that the total ENTROPY can only increase over TIME for an isolated system, meaning a system which neither energy nor matter can enter or leave. The total entropy can remain constant in ideal cases where the system is in a steady STATE (equilibrium) or undergoing a reversible process. |

How does the second law of thermodynamics apply to living organisms? |
|
Answer» According to the second law of thermodynamics when an energy is put to use a part of it is always CONVERTED into unuseful form of energy.When photosynthesis starts energy it is UTILISED by living organisms by which unuseful energy is still CREATED and lost. The AMOUNT of energy released is always less than the actual energy released by any living organism.Example:-When a BULB is grown first it is converted it into heat energy then into light energy. Hence, energy is lost in the form of heat energy.Similarly, when a machine is used a part of it is lost in friction and moving other parts of machine. |

Why does lithium and magnesium reacts slowly with water? |
|
Answer» sity of lithium is about half that of water and so it first floats on the water SURFACE and ultimately vanishes FORMING a colorless lithium hydroxide solution. Thus, it reacts very SLOWLY with water. Magnesium has a diagonal relationship with lithium and HENCE it also reacts very slowly with water. |

How to find lewis dot structure of PO43- Using n1 n2 and n3 PLZ NO SPAM IF U KNOW THEN ONLY ANSWER |
|
Answer» Explanation:For the PO4 3- Lewis structure use the periodic table to find the TOTAL NUMBER of valence electrons for the PO4 3- molecule. Once we know how many valence electrons there are in PO4 3- we can distribute them around the central atom with the goal of FILLING the outer shells of each atom. In the Lewis structure of PO43- there are a total of 32 valence electrons. For the Lewis structure for PO4 3- you should take formal charges into ACCOUNT to find the best Lewis structure for the molecule. Remember, PO4 3- has a negative three CHARGE on the molecule. For the Lewis structure you'll need to have a total charge for the molecule of 3-. PLEASE MARK ME AS THE BRAINLIEST |

Is cold bad for lithium-ion batteries? |
| Answer» LITHIUM batteries rely on chemical reactions to WORK, and the cold can slow and even stop those reactions from occurring. ... Unfortunately, charging them in low temperatures is not as effective as doing so under NORMAL weather conditions because the ions that PROVIDE the charge do not MOVE properly in the cold weather.Explanation: | |
| 32. |
How is enthalpy used in everyday life? |
|
Answer» Change in enthalpy can apply to refrigerators and hand warmers. In a fridge, REFRIGERANTS such as Freon are evaporated. The enthalpy of vaporization (liquid to gas energy change) is EQUIVALENT to the coldness of your food. Some people USE chemical HEAT PACKS (hand warmers) outside |
