-13,9 celcius
yg lainnya lupa rumus
tadi ada yang jawab katanya jawabannya -28 yang bener yang mana ya kak?
7˚F = …. ˚C = …˚R = … ˚K
1. 7˚F = …. ˚C
= 5/9 × (t - 32˚)
= 5/9 × (7˚-32˚)
= 5/9 × -25˚
= -13,5˚C

2. 7˚F= ….˚R
= 4/9 × (t - 32˚)
= 4/9 × (7˚-32˚)
=4/9 × -25˚
= -10,8˚R

3. 7˚F = … ˚K
= 5/9 × (t - 32˚) + 273˚
= 5/9 × (7˚-32˚) + 273˚
= 5/9 × -25˚ + 273˚
= 13,5˚ + 273˚
= 286,5˚K
makasih
