It depends on the year that you bough it in. IF it is within the last 5 yrs. they should be good for the next 5 1/2 yrs.
I've heard they are good for about 2 hours. I've never used it for more than 20 minutes at a time, and I usually get like 4-5 uses out of it at that rate.
It can last for months or just a week, it really depends on how much you grill and at what tempeature.
A Coleman sixteen point four ounce propane cylindrical tank will often last its user approximately an entire year under the optimal use and the best case scenarios of its environment.

Propane stove. Propane water heater. Propane fridge. Propane heater. Propane gas lights. Propane generator w/storage cells for electric use. Propane A/C units (not cheap, but have long life.)
Purging a propane cylinder is done by first removing air in cylinder that has never had propane in it. Then cylinder is is filled with propane vapor appx. 15psi this vapor is then blown out. This process is then repeated appx.4-5 times this removes all unflamable gas from cylinder and replaces it with propane vapor. If a new cylinder is not purged the propane will not burn properly.
The factors that determine how long a propane generator can run are the size of the propane tank, the size of the generator, the brand of generator, and what is being used under the generator's power.
About 6 hours
One pound of propane will produce 21,622 BTU's. 20 pounds of propane will produce 432,440 BTU's. A heater that produces 80,000 BTU's per hour will produce heat for almost 5 1/2 hours.
Provided it is stored satisfactorily it should last for years. I suppose the valve might leak eventually, over a long time.
The propane will last until the tank is empty.
About 120psi for a 16 oz propane tank
because her name is too long if they put two names on the screen they wound not fit her last name is Coleman
1 gallon of Propane ~= 4.23 lbs ~= 91500 Btus 1 lbs of Propane ~=22000 Btus 20 lb tank of propane holds approx 4 gallons of propane (366000 BTUs) Your grill will last 366000 BTUs/ Grill BTU output hrs
The length of time a propane tank lasts on a hot air balloon depends on several factors. These factors include the size of the tank, the operator's discretion, and wind. Most last several hours.
I believe portable barbecue grills last as long as the propane tank you have, possibly buy a few extra of them, just to make sure they last through the whole entire football game.
That would depend on too many things that are no listed. Need to know what the desired temperature is.. What the BTU rating of the heater is, what the efficiency rating is, what the R value of the structure is.
Generally, a good propane heater is large and has a thick metal surrounding. One that is made of cheap, thin metal is probably not a good heater because it will not last long.
Surely it depends on your rate of usage-what appliances you run from it
A 20 pound propane tank holds 4.1 gallons of LP which equates to about 0.016 cubic meters. If your heater burns 3 m3 per hour the tank will last about 19 seconds. If you meant .0003 then it will last 51.73 hours.
A cylinder? A cylinder is still a cylinder regardless of how long it is.
