What type of rock is this? (i found it outside and it just caught my eye and it feels great having it around)

Nice looking rock, dont know what type it is but nice rock.

Yea idk what kind of rock it is but thats nice .

i'd say that the moon rock is about 2.2 billion years old.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
