Be careful on this one! Mass is always conserved, based on the law of conservation of mass. Since their was a change in state, we went from a solid to a gas, so, the weight would be lighter, not the mass.
Same amount of mass.
If it's to balance the equation then it's already balanced.
Answer:
The answer to your question is P2 = 1.52 atm
Explanation:
Data
Volume 1 = V1 = 4.54 l
Pressure 1 = P1 = 1.65 atm
Temperature 1 = T1 = 75°C
Volume 2= V2 = 5.33 l
Pressure 2 = P2 = ?
Temperature 2 = 103°C
Process
1.- Convert temperature to °K
Temperature 1 = 75 + 273 = 348°K
Temperature 2 = 103 + 273 = 376°K
2.- Use the combine gas law to find the final pressure
P1V1/T1 = P2V2/T2
-Solve for P2
P2 = P1V1T2 / T1V2
-Substitution
P2 = (1.65 x 4.54 x 376) / (348 x 5.33)
-Simplification
P2 = 2816.62 / 1854.84
-Result
P2 = 1.52 atm
The magnitude of the force required to change the length of a spring-like object is directly proportional to the spring constant and the displacement of the spring. Elastic potential energy is directly proportional to the square of the change in length and the spring constant.
So the whole point is that you need a abstract.
