Question

transforme 20c em farenheit e kelvin​

Answer 1

celsius pra farenheit

$\frac{c}{5} = \frac{f - 32}{9} \\ \frac{20}{5} = \frac{f - 32}{9} \\ 5f - 160 = 180 \\ 5f = 180 + 160 \\ 5f = 340 \\ f = 340 \div 5 \\ f = 68$

celsius em Kelvin

$c = k - 273 \\ 20 = k - 273 \\ k = 273 + 20 \\ k = 293$
