According to the first law of
To review:
The given blank space in the statement, “according to the first law of thermodynamics, energy can be neither _________ nor __________. Energy occurs in two major forms: _________, the energy of movement, and _________, or stored energy.”
Introduction:
Energy is a quantitative property, which is required to do work and can be of two basic types. One type of energy is the one which is stored energy and is known as potential energy. The other type of energy is characterized by movement and is known as kinetic energy.
Explanation of Solution
According to the law of conservation of energy, the entire energy of a system always remains constant. In other words, energy can neither be created nor destroyed. It can be transformed from one form to another. This principle is known as the law of conservation of energy and is stated as the first law of thermodynamics.
The main two types of energy are – kinetic energy and potential energy. The kinetic energy is characterized by movement or motion. For example, a person running in a marathon or a ball rolling downhill or a moving car are using kinetic energy. The other type of energy is potential energy, which is characterized by the position of the object. It is, therefore, the stored energy in an object. For example, an object kept at a height or a compressed string.
According to the first law of thermodynamics, energy can be neither destroyed nor created. Energy occurs in two major forms: kinetic energy, the energy of movement, and potential energy, or stored energy.

- Which of the following is TRUE regarding the second law of thermodynamics? The quality of the energy in the universe increases over time. The entropy of the universe is always increasing. Energy is conserved in the universe. The energy of the universe is always increasing. Entropy is conserved in the universe.arrow_forwardBeginning physics students are often taught the basicconcepts of thermodynamics with two phrases: First,you can never win. Second, you can never break even.Explainarrow_forwardImagine you are working in a lab, and you are performing two chemical reactions. You notice that Reaction A occurs much faster than Reaction B, and that both reactions release the same amount of heat. Which of the following conclusions can be made from your observation? Reaction A has the same activation energy as Reaction B, and the AG of Reaction A is more negative (i.e., a larger negative number) than the AG for Reaction B. Reaction A has a lower activation energy than Reaction B, and the AG of Reaction A is the same as the AG of Reaction B. Reaction A has a higher activation energy than Reaction B, and the AG of Reaction A is the same as the AG of Reaction B. Reaction A has the same activation energy as Reaction B, and the AG of Reaction A is less negative (i.e., a smaller negative number) than the AG for Reaction B.arrow_forward
- Which of the following best describes a thermodynamically favorable (spontaneous) chemical reaction? It has a ΔG that is greater than zero and is endergonic. It has a ΔG that is greater than zero and is exergonic. It has a ΔG that is less than zero and is endergonic. It has a ΔG that is less than zero and is exergonic.arrow_forwardWhich is not true regarding the 1st Law of Thermodynamics? Energy cannot be destroyed.

- Discuss the following statement: “enzymes and heat are alike in that both can speed up reactions that—although thermodynamically feasible—do not occur at an appreciable rate because they require a high activation energy. diseases that seem to benefit from the careful application of heat—in the form of hot chicken soup, for example—are therefore likely to be due to the insufficient function of an enzyme.”arrow_forwardWhy is it not enough to just rely on either thermodynamic data alone ...
