What is molecular solvation?
A molecular solid is a crystalline solid held together by intermolecular forces and composed of discrete molecules held together by van der Waals interactions. This type of solid can be contrasted with metallic solids and covalent solids, which are held together by stronger bonds.As one would expect based on the aforementioned information, molecular solids tend to be melted or sublimated at lower temperatures than other types of solids, because of their weak intermolecular bonding.
What order does water in a puddle take part in the water cycle?
first it evaporates into a cloud, then its held up in the cloud for a time and when cold and warm air mix it comes back down to earth.
Why is G C content is more stable at high temperatures than DNA with a high A T content?
Guanine (G) and Cytosine (C) are joined together with three hydrogen bonds, whereas Adenine (A) and Thymine (T) are only held together with two. This makes G and C more stable than A and T.
Is styrofoam polar or nonpolar?
Thermoplastic is a term that refers to a substance turning into plastic when exposed to extreme temperatures. This would make Styrofoam thermoplastic.
What is a tcf food?
A "TCF" (time and temp. control food safety) is now being widely used as opposed to the "PHF"- (potentially hazardous foods) acronym. it is any foods that need constant temperature monitoring for safety. hot held foods 139 F. Minimum, cold held foods 41 F. or lower.
What is the temperature for buffet?

Meat
What temperature should hot foods be kept at?
Food should be hot held at 135 F for no more than 4 hours. Food should be reheated to 165 F for at least 15 seconds before the 4 hour point is reached.
At what temperature should cold food be maintanied?
Generally, potentially hazardous foods should be stores at 40°F or below. Vacuum-packaged foods that require refrigeration should be stored at 38°F or below, due to concerns about Clostridium botulinum.
How do you prevent time-temperature abuse when transporting food?
The term "time and temperature abuse" refers to the transport and storage of foods or when foods are "not cooked to the recommended minimum internal temperature, not held at the proper temperature, or not cooled or reheated properly". Temperature danger zone occurs between 41°F to 140°F. Prevention means keeping foods out of that danger zone.
What colds can you catch from climbing mountains?
Only the type of cold that you feel from low temperatures. You can not catch the infectious disease called the common cold from climbing mountains or from being cold. The common cold is caused by viruses that you catch from other people, it has nothing to do with cold weather. Check out the related questions in the related questions section for more about this long held belief/myth that you catch a cold from being in the cold. It is just a myth from before people knew about viruses.
How long may potentially hazardous foods be held in the temperatures danger zone before they must be discard?
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.
Is it safe to cook frozen meats?
yes you can, providing you put it in the fridge, so bacteria dose not get to it.Do not defrost frozen meat and poultry products at room temperature. Keeping the products cold during defrosting is the key to preventing bacteria from growing.Always cook fresh meat and poultry products immediately after microwave defrosting. During microwave defrosting, random areas will sometimes begin to cook, creating temperatures easily high enough for harmful bacteria to thrive. To defrost meat or poultry products in cold water, do not remove original packaging. Be sure the package is airtight or put it into a leak-proof bag before submerging the product completely in cold water, changing the water every 30 minutes so that it continues to defrost. Note: Foods defrosted in the microwave or by the cold-water method should be cooked before refreezing because they may have been held at temperatures higher than 40 F. Wash all utensils, cutting surfaces and counters with hot, soapy water after contact with meat and poultry. If possible, use a separate cutting board for fresh meat and poultry products. Wash hands thoroughly in hot, soapy water before and after handling meat and other fresh foods. Keep fresh meat and meat juices away from other foods, both in the refrigerator and during preparation. Never place cooked foods on the same platter, board or tray that held fresh meats or poultry.
