Answer:
See explanation
Explanation:
According to chemistry libretexts(2020); "The rms velocity is directly proportional to the square root of temperature and inversely proportional to the square root of molar mass. Thus quadrupling the temperature of a given gas doubles the rms velocity of the molecules. ... As the temperature of a gas is increased, the velocity of the molecules is also increased."
Hence considering two gases for which the Vrms of the particles of one is high and that of the other is low, we can conclude that the gas having the higher Vrms is at a higher temperature than the gas having a lower Vrms according to the foregoing.
Assuming that the space within the solid or liquid is vacuum, it is not matter because there is no mass inside. However, there is a volume. The volume inside a solid would have regular straight sides because atoms of a solid is compactly arranged. For liquids, the space could be irregular curves and paths because the atoms in a liquid are free-flowing.
1 2 2 1 is the answer so u are correct
Answer:
The addition of energy through the chemical reaction when substance combines and gets decomposed.
Explanation:
- Chemical changes take place when the substance combines with some other to form a chemical synthesis and gets alternatively decomposed into 2 different substances through chemical reactions.
- As when the chemical reactions occur the atoms rearrange themselves. As these are accompanied by the energy changes.
- Such as those of sodium and water to produce sodium hydroxide and hydrogen. The chemical changes are found in organic, inorganic, and biochemical changes.

उस पदार्थ या यौगिक को अभिकर्मक (reagent) कहते हैं जो किसी तंत्र में रासायनिक अभिक्रिया उत्पन्न करने के लिये डाला या मिलाया जाता है। उस पदार्थ को भी अभिकर्मक कहेंगे जिसे यह जांचने के लिये मिलाया जाता है कि कोई अभिक्रिया होती है या नहीं। इस तरह के कुछ वैश्लेषिक अभिकर्मक हैं - फेहलिंग का अभिकर्मक (Fehling's reagent), मिलॉन का अभिकर्मक (Millon's reagent) तथा टॉलीन का अभिकर्मक (Tollens' reagent)।
