The 2 main components of the internal energy of a substance are:
The internal energy is a sum of kinetic and potential energy.
E_k (total)=E_k(translational) + E_k(rotational) + E _k(vibrational)
Internal energy is the microscopic energy contained in a substance, given by the random, disordered kinetic energy of the molecules. Further it includes the potential energy between those molecules, and the nuclear power contained in the atoms of those molecules.
The internal energy of a system is extensive property. it's a state property. The exchange is independent of the path followed. Change in internal energy of a cyclic process is 0.
Internal energy is affected by factors including pressure, volume, and temperature. All the variables on this listing are state functions.

Answer: -
60 mL of potassium chloride 20% should be diluted to prepare 480 ml of potassium chloride 2.5%
Explanation: -
Volume of potassium chloride solution = 480 mL
Percentage of potassium chloride = 2.5%
Amount of Potassium chloride = 
x 480 mL
= 12 mL
Let the required amount be R.
20 % of R = 12 mL.
x R = 12mL
R = 60 mL.
Thus, 60 mL of potassium chloride 20% should be diluted to prepare 480 ml of potassium chloride 2.5%
Answer:
Hey
of course, the damage of a collision depends upon how fast to objects are moving at each other and how strong they are. If you have two tanks moving at each other 2 miles per hour it will be very little damage and the ->shape<- will not change much, maybe a dint or two. But if two balloons filled with water are moving at each other 5000 mph they will completely evoporate in a burst of light, and their ->shape<- will change very much. This is how shape and motion are related.
Hope it helped

<span>The scientific method is a systematic way of questioning about the world around us and answering questions. The number of steps varies from one description to another, mainly when data and analysis are separated into separate step, but this is a fairly standard list of 6 scientific method steps, which you are expected to know for any science class:
1. Form a Hypothesis. This is a sort of educated guess about what you expect.
2. Design an Experiment to test your hypothesis. An experiment has an independent and dependent variable. You change or control the independent variable and record the effect it has on the dependent variable.
3. Conduct Experiment
4. Record data and observations and analyze what the data means. Often, you'll prepare a table or graph of the data.
5. Form a Conclusion. Conclude whether to accept or reject your hypothesis. Communicate your results.</span>
One possible answer could be that a chemical reaction has occurred.
