If placed in an environment at room temperature, most food will cool to said temperature after two hours, however this is entirely dependant on the food in question.
However, according to the US FDA Model Food Code, for food service, cooked food should be cooled down to 70°F within 2 hours. From that point, you have another 4 hours to get the internal temperature down to 40°F.
When cooling cooked food, once the food temperature gets down to 135 degrees F, the clock starts ticking and it should be cooled to 70 degrees F within 2 hours. In the next 4 hours, it should be cooled to 41 degrees F.
to test the temp of a case of sour cream, should i open one and submerge thermometer into it

Food doesn't specifically have to be cooled in a certain time. Food must be covered once it has cooled however, so don't leave it out for more than a few hours. ANSWER: For safety reasons, food must be cooled within 4 hours, otherwise pathogens can grow and make the food unsafe to eat. Never leave any food out of the refrigerator for more than 4 hours as well, for the same reason.
You remove heat. Nitrogen must be cooled to -196 degrees Celsius to become a liquid.
Check you turned the oven on. Also ensure that you have set the oven at the correct temperature.

A large quantity of food must be cooled by immediate refrigeration. The refrigerator's temperature should be set as cold as possible and, if practicable, the food to be cooled should be refrigerated on shallow trays or dishes to allow for quick cooling. You could also put your trays of food into the freezer until cold, before covering or sealing and refrigerating.A large quantity of food must be cooled by immediate refrigeration.

The same as most substances, CO2 must be cooled and put under increased pressure to become a solid. At one atmosphere, CO2 must be cooled to a temperature of -78.5 degrees Celsius to solidify. At height pressures CO2 solidifies at higher temperatures, however solid CO2 never exists at a temperature above -56.4 degrees Celsius.
Hold hot foods at 135 F degrees and check temp every 4 hours. At 4 hours, if temp has fallen below 135 degrees F, then throw it out. Do not reheat it. Do not eat it or let anyone else eat it.
In the US, the Food and Drug Administration department recommends a minimum temperature of 135 º F (57 º C). The danger zone is 41º F - 135º F. Potentially hazardous foods exposed to this temperature range for a cumulative total of more than 4 hours are not safe to eat. Pasta and rice dishes should be cooled to below 41ºF as quickly as possible to prevent the growth of Bacillus cereus that can produce a toxin, especially in foods that are cooled slowly. Because this toxin is heat-resistant, it's not destroyed by reheating to any temperature.
it must be cooled in the desiccator in order to take the correct measurement on the scale while performing the experiment.
It is permissible to hold hot food without temperature controls for up to four hours if the following conditions are met:Food must be held at 135 degrees Fahrenheit or higher before the food is removed from the temperature control.Label the food upon receipt with the time it must be discarded. The discard time is four hours after the food has been removed from the temperature control.After the four hour time limit, the food must have been served, consumed, or thrown away.
Yes, if a custard tart is not eaten within a few hours after it is baked and cooled, it should be refrigerated. Any leftovers must also be refrigerated.
Once thawed, the food should be cooked properly. Once cooked, the food can be eaten hot, or quickly cooled and put into a fridge to be eaten in a day or two. The food should not be refrozen once thawed.
