Question

DETERMINE A VARIAÇAO DE TEMPERATURA SOFRIDA POR UM CORPO DE 50 G APOS GANHAR 500 CAL SENDO c=2cal/gºc .

Answer 1

$\boxed{Q = m*c*\Delta\Theta}$

$500 = 50.10^-^3*2.\Delta\Theta\\\\\\ 500 = 100.10^-^3\Delta\Theta\\\\\\ \Delta\Theta = \frac{500}{100.10^-^3}\\\\\ \boxed{\Delta\Theta = 5000\°C}$

Answer 2

Q=m.c.Δθ
500 = 0,05.2.Δθ
500/0,1=Δθ
Δθ=5000 ºC
