When a substance melts it has changed from a solid to a liquid state while when a substance is set on fire is changes from liquid to gaseous state as it boils.
<h3>What is change of state?</h3>
Change of state of matter is the transformation of a substance from one phase of matter to another.
When a substance melts it has changed from a solid to a liquid state while when a substance is set on fire is changes from liquid to gaseous state as it boils.

We are given with
V = 12L
T = 298 K
P = 1000 kPa
We are asked to get the number of moles, n
We can solve this using the ideal gas law
PV = nRT
n = PV / RT
Simply substitute the values and use the appropriate value for R.
Tissues and organ systems
Explanation:
It is known that for first order reaction, the equation is as follows.
t = ![\frac{2.303}{K} log \frac{[C_{4}H_{8}]_{o}}{[C_{4}H_{8}]_{t}}](https://tex.z-dn.net/?f=%5Cfrac%7B2.303%7D%7BK%7D%20log%20%5Cfrac%7B%5BC_%7B4%7DH_%7B8%7D%5D_%7Bo%7D%7D%7B%5BC_%7B4%7DH_%7B8%7D%5D_%7Bt%7D%7D)
t = ?, K = rate constant = 79 1/s
Initial conc. of
= 1.68
Decompose amount of
= 52% of 1.68
= 
= 0.8736
= 0.87
Now,
= (1.68 - 0.87)
= 0.81
Therefore, calculate the value of t as follows.
t = ![\frac{2.303}{K} log \frac{[C_{4}H_{8}]_{o}}{[C_{4}H_{8}]_{t}}](https://tex.z-dn.net/?f=%5Cfrac%7B2.303%7D%7BK%7D%20log%20%5Cfrac%7B%5BC_%7B4%7DH_%7B8%7D%5D_%7Bo%7D%7D%7B%5BC_%7B4%7DH_%7B8%7D%5D_%7Bt%7D%7D)

Thus, we can conclude that 0.00921 s will be taken for 52% of the cyclobutane to decompose.
