3. how much cooler is the melting point of silver than gold? gold melts at 1946 f and silver melts at 1762.

Answer 13

Answer 14

do u want me to readu the whole ?

Answer 15

no just check whether day temp< night temp

Answer 16

day temp is 260 far and night is -280 f

Answer 17

k fine then temp drops by 260+280=540f
this is bcoz initially it was at 260 then to reach -280 it has to drop by 540 f

Answer 18

ok

the 3rd
just subtract
1946-1762=184f
