What would happen if you touched an object that is the same temperature as your hand? Would any heat transfer happen? Explain your answer in 4-5 sentences.

Answers

Answer:

Explanation:

When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the object

which means that it refers to transfer through a selectively permeable partition, the contact path.[1] For the relation of thermal equilibrium, the contact path is permeable only to heat; it does not permit the passage of matter or work; it is called a diathermal connection. According to Lieb and Yngvason, the essential meaning of the relation of thermal equilibrium includes that it is reflexive and symmetric. It is not included in the essential meaning whether it is or is not transitive. After discussing the semantics of the definition, they postulate a substantial physical axiom, that they call the "zeroth law of thermodynamics", that thermal equilibrium is a transitive relation. They comment that the equivalence classes of systems so established are called isotherms

What does the Law of Conservation of Momentum stare about the momentum in a system in an inelastic collision?

Answers

Answer:

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Explanation:

Answer:

For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.

Transfer this mixture in a blender and blend it on high speed for 15 seconds. Filter the blended mixture, using a strainer, into a measuring container. Observe the amount of mixture you obtain after filtration. Add liquid detergent equal to 1/6 volume of the obtained pea mixture. Mix by swirling. Allow the mixture to rest for about five to ten minutes. Transfer this mixture to test tubes. Fill the tubes to about 1/3 of their volume. Add a pinch of meat tenderizer to each of these tubes. Mix gently to avoid damaging the DNA. Tilt the test tube, and pour alcohol (75% isopropyl alcohol or 95% ethanol) down the sides of the tube. Add alcohol to about 2/3 volume of the tube. You will obtain two layers. The layer at the top contains the DNA.Now that you are done with the DNA extraction process, answer the following questions: What purpose does blending the pea mixture serve? Why do you need to add liquid detergent? What role does the meat tenderizer play? Why is alcohol added and why does the DNA get extracted in the alcohol layer?
