Thw...thermoplastic heat resistant wire building wire type. In most applications replaced by type thhn which has a smaller od and
THHN wire is moisture resistant thermoplastic allowed for use in dry and wet locations. Maximum temperature is 60 C or 140 F. Being thermoplastic it should not be handled below 0 C as cracking of the insulation could easily occur.
Cross link polyvinyl chloride RW90 (PVC) and THHN are two common types of insulation THHN wire stands for thermoplastic high heat resistant nylon coated wire. THWN stands for thermoplastic heat- and moisture resistant nylon coated wire.
It's a table that shows the ampacity ratings for the particular wire size and insulation you are using. Example: #12 THHN CU is rated @ 30amps under the 90 degree column. (#12)is the wire size, (THHN)is the type of insulation on the wire (CU)is copper. You shouldn't be using the chart unless you're a qualified electrician simply because there are many sub rules and exceptions.

Not sure what you mean by "gas" rated wire. If you mean "gasoline resistant" you probably have type THHN wire insulation. Size #8 THHN is not suitable for a 60 amp application anywhere.
yes
#1 copper thhn
yes
I would need more detailon your question but what i can tell you is 100' of #10 THHN eire is 8320grams with insulation and 7110 grams as bear copper wire. Now what i am trying to figure out is if that copper wire is 100% copper or not?

The conductor can be pulled into conduit and then buried but it is not certified for direct earth burial.
