Arigid container holds a gas at a pressure of 55 kpa and a temperature of -100.0*c. what will the pressure be when the temperature is increased to 200*c

P2 = 150.4 KPa

Explanation:

Gay-Lussac's Law:

at constant volume, the pressure of a gas varies directly with the temperature

∴ P1 = 55 KPa

∴ T1 = - 100.0°C ≅ 173 K

∴ T2 = 200°C ≅ 473 K

⇒ P2 = ?

⇒ P2 = (473 K)(55 KPa) / (173 K)

⇒ P2 = 150.4 KPa

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
