How Does Temperature Change with Volume in a Quasi-Static Adiabatic Process?

AI Thread Summary
In a quasi-static adiabatic process for an ideal gas, the relationship TV^(γ-1) = constant holds true, indicating that temperature and volume are inversely related under adiabatic conditions. To find the radius at which the temperature drops to 2000 K after a uranium fission bomb detonation, the Ideal Gas Law and the adiabatic process equation PV^γ = constant can be applied. The initial conditions involve a gas sphere with a radius of 50 ft and a temperature of 300,000 K. Calculating the new radius requires understanding the changes in volume and temperature as the gas expands. This analysis is crucial for understanding the thermodynamic behavior of gases in explosive scenarios.

Hello Friends!

can anybody help me?

show that for a quasi static adiabatic process of an ideal gas, the following reaction holds

TV^{\gamma-1}}=constant

Secondly:::

At about 100ms after detonation of a uranium fission bomb, the "ball of fire" cosists of a sphere of gas with a radius of about 50 ft and a temperature of 300,000 degree Kelvin. At what radius is the temperature 2000 K?

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
