Answer: C diamond has a different crystal structure from graphite
Explanation:
<u>Answer:</u>
<em>The percentage error in the measurement is 2.4%
</em>
<u>Explanation:</u>
The measurement made by the student is 
.
But the actual value of density is 
The formula to calculate percentage error is
percentage error = 
Hence percentage error in this case is given by
<em>Percentage error = 
</em>
<em>= 
</em>
A physical quantities value will be determines by various quantities. If errors are made in measuring any of these quantities there will be error in the measurement of the final physical quantity as well.
Here density of a substance is a derived quantity determined by measuring mass and volume of that substance.<em> If errors are made in mass and volume measurements the density value will also be erroneous.

Answer : The correct option is, (2) gas to liquid
Explanation :
Entropy : It is defined as the measurement of randomness or disorderedness in a system.
The order of entropy will be,
As we are moving from solid state to liquid state to gaseous state, the entropy will be increases due to the increase in the disorderedness.
As we are moving from gaseous state to liquid state to solid state, the entropy will be decreases due to the decrease in the disorderedness.
In option 1, 3 and 4, the entropy increases. while in option 2, the entropy decreases.
Hence, the correct option is, (2) gas to liquid
The answer will be A.
Sorry if it was incorrect but that’s the closest answer.
Answer:
Okay, I think I may actually have an answer for you. I would go with C, "The number of particles able to undergo a chemical reaction is less than the number that is not able to."
Explanation:
I just took a quiz with a similar question, and B is the only gas particle that is able to react. This cancels out all the other answers, as A and B are obviously incorrect based on that information, and it rules out D because T1 is the only sample with a particle able to react. I hope this helps!
