I believe the correct answer from the choices listed above is the second option. With this information, he was able to conclude that the beam was negatively charged. His cathode ray<span> tube experiments led to a very important scientific discovery, the electron. Hope this answers the question.</span>

Answer:
The answer to your question is 720.5°K
Explanation:
Data
Volume 1 = 285 ml
Temperature 1 = 355 °K
Pressure 1 = 1.88 atm
Volume 2 = 435 ml
Temperature 2 = ?
Pressure 2 = 2.5 atm
Formula
To solve this problem use the combined gas law
P1V1 / T1 = P2V2 / T2
- Solve for T2
T2 = T1P2V2 / P1V1
- Substitution
T2 = (355)(2.5)(435) / (1.88)(285)
- Simplification
T2 = 386062.5 / 535.8
- Result
T2 = 720.53°K
Conclusion
The gas must be heated to 720.5°K
an object is more dense if there is more weight in the same area, its because of the amount of particles and the weight of the particles. eg, 1cm cubed of gold would weigh alot more than 1cm cubed polystyrene, so gold is more dense
