Micra fuel tank leak

The natural state of petrol is gaseous.

No it’s not, it’s liquid.

It's only liquid under some pressure.

Gasoline is a volatile liquid

We got there in the end.

Gasoline evaporates relatively quickly, often within hours, with the rate influenced by factors like temperature, exposure area, and the type of gasoline blend.

Here's a more detailed explanation:

• Volatility:
  Gasoline is a volatile liquid, meaning it readily turns into a gas (vapor) at relatively low temperatures.
  
  
• Evaporation Time:
  A small amount of spilled gasoline can evaporate within 1 to 3 hours, while larger amounts or those in storage tanks may evaporate more slowly, potentially over several hours or even days.
  
  
• Factors Affecting Evaporation Rate:
  • Temperature: Higher temperatures accelerate evaporation.
    
    
  • Exposure Area: The larger the surface area of the gasoline exposed to the air, the faster the evaporation.
    
    
  • Gasoline Blend: Winter-blend gasoline, which is more volatile, evaporates faster than summer-blend gasoline.
    
    
  • Wind: Wind can increase evaporation rates by carrying away the gasoline vapors.
• Evaporation in Vehicles:
  Gasoline in a fuel tank can evaporate, especially during hot weather or if the fuel cap is not properly sealed.
  
  
• Evaporation in Storage:
  Gasoline storage tanks often have internal floating roofs to minimize evaporation by reducing the surface area exposed to the atmosphere
  
  
• Weight Loss:
  The evaporation rate can be measured by determining the weight loss of the gasoline over time.
  
  
• Vapor Pressure:
  The changes in vapor pressure and evaporation rate of gasoline can be expressed by the exponential of the weight loss fraction.

. You regard that as proof?!. Perhaps you'd like to find some AI article (it's not a "thread", by the way) that tells you how fast a tank full of petrol will evaporate with the cap left off? Or are you claiming your "victory" by virtue of not being able to understand the difference between a "spill" and a "tank"?

 

[DiyNutJob]

Either your tank has a hole, and therefore a potential leak, or it doesn't. Which is it ?

It doesn't, unless cap untightened or seal obstructed by debris.

We didn't. Volatile mean evaporative.

This thread is the proof. AI is just confirmation of the proof.

OK, you have convinced us that you are simply an AI bot..

Yes, and to evaporate, a substance must be….oh forget it, you’ll never understand.

 

[DiyNutJob]

Yes, and to evaporate, a substance must be….oh forget it, you’ll never understand.

To evaporate, a substance must be highly energetic or it will never lift off. To prevent lift off, you must use a container that can resist the lift off pressure. It can be hard for you to understand if you never did your o'level physics. See this for a visualisation of the process:

The natural state of petrol is gaseous.

So, is petrol a liquid or as you said earlier, a gas?

At ambient temperature and pressure it's a gas. So it naturally reverts to gas from liquid. The gas has a larger volume than the liquid state. This creates the pressure for it to escape from a container.

I’ll try again. Is it liquid or gas when it comes out of the petrol pump hose and keep it in your fuel tank in a temperature range of say, -20°c and +40°c.? In other words, the average temperature range we live in.

It is liquid when pressurised. It is gas when unpressurised.

 

[Mottie]

It is liquid when pressurised. It is gas when unpressurised.

We're getting there. Painfully, but getting there. So, If I filled an open (unpressurised) bucket with unpressurised petrol, would it remain liquid or would it change into a gas?

It changes into gas. Are you sure you know where you are going?

 

[Mottie]

It changes into gas. Are you sure you know where you are going?

Look at this. It might help you l though I doubt it, you are beyond help. Anyone who believes they have 'lifetime' oil in their engine that never needs changing is, quite simply, an idiot.
