I understand there is a relationship between pressure & temperature in a sealed rigid container.
An open container is placed in a freezer at -15 degrees C then the door is opened and the cap replaced with the freezer at 1000mb what will the pressure be within the container if it is placed in a room with an ambient temperature of 40 degrees C
Same answer as yesterday:
Thank you again DRWLS but ref my post "site not working correctly". Still cannot read the answer. Most frustrating. Can I close the adverts? Mike
Here is the same answer, again.
If you cover an open cold container after removing it from the freezer, warm air at 313 K and P = 1000 mb will come in contact with the contents, and (after sealing with a lid) chill at constant volume to 258 K.
Since P/T = constant in this case, you end up with a pressure P' that satisfies the equation
P'/258 = Po/313, where Po = 1000 mb
P' = 258/313 * 1000 = 824 mb
Note that I had to use Kelvin temperatures.
