Energy cannot be created or destroyed, so the answer would be c.) not a or b.
Hope this helps!
I’m pretty sure the first option is the right answer
This law<span> states that the pressure of a given amount of </span>gas<span> held at constant volume is directly proportional to the Kelvin temperature. Therefore, the variables are pressure and temperature. Hope this answers the question. Have a nice day.</span>
Answer: 6. Rb Cl
Because, as the electronegativities of the elements, Rb and Cl, indicate this an ionic compound. Meaning that the elements are as ions ( Rb+ Cl-)., which in liquid (molten) state are charges that move freely, making the compound a good conductor of electricity.
The changes in matter/energy can be classified as follows:
- Physical changes - Crystallizing salt from seawater
- Chemical changes - ripening fruit
- Nuclear changes - production of elements in the stars
<h3>What are physical, chemical and nuclear changes?</h3>
Matter and energy undergo physical, chemical and nuclear changes.
Physical changes are changes in which no new product is formed.
Chemical changes are changes in which no new product is formed.
Nuclear changes are changes in which no new product is formed.
Examples of each of the given changes is as follows:
- Physical changes - Crystallizing salt from seawater
- Chemical changes - ripening fruit
- Nuclear changes - production of elements in the stars
Therefore, matter/energy undergo changes.
