The amount of energy before and after any energy transformations remain the same because energy cannot be created or destroyed. From the law conservation of energy; any time energy is transferred between two objects, or converted from one form into another, no energy is created and none is destroyed. The total amount of energy involved in the process remains the same.
Answer:
I believe the answer is B.
The reason is because the molecules didnt come togeather around that time
Answer:
1973. K
Explanation:
PV=nRT
(5.4)(120)=(4)(0.0821)T
648=(0.3284)T
1973. = T
Using the ideal gas equation, T is measured in Kelvin.
Or, you could isolate T:
T = PV/nR
The answer is the same.
