False because they can turn back to their original form a chemical change would be like burning paper it can’t be changed back to it’s original offer it’s burnt
Answer: (2) increases
Explanation: Entropy is the measure of randomness or disorder of a system. More is the random arrangement of molecules in a system , more is the entropy of the system. More ordered is the arrangement of molecules in a system, less is the entropy of the system.
When carbon dioxide sublimes, it means solid carbon dioxide is directly changing to gaseous state without undergoing into liquid state, thus the molecules will be more random and thus the entropy will increase.

Answer:
The new temperature of the gas is 200 Celsius degrees.
Explanation:
Charles's Law consists of the relationship between the volume and temperature of a certain amount of ideal gas, which is maintained at a constant pressure, by means of a proportionality constant that is applied directly.
In this way, Charles's law is a law that says that the quotient that exists between volume and temperature will always have the same value:
Assuming you have a certain volume of gas V1 that is at a temperature T1 at the beginning of the experiment, if you vary the volume of gas to a new value V2, then the temperature will change to T2, and it will hold:
In this case:
- V1= 20 L
- T1= 100 °C
- V2= 40 L
- T2= ?
Replacing:
Solving:
T2=200 °C
<u><em>The new temperature of the gas is 200 Celsius degrees.</em></u>
Answer:
8.067 g/cm^3
Explanation:
Density = Mass/Volume
where mass = 121g and....
Volume = (35 - 20) = 15ml
where 1ml = 1cm^3
So Density = 121/15
;Density = 8.067 g/cm^3
