Calculeaza caldura specifica a alamei stiind ca o piesa de alama cu masa 200g,incalzita de la 12°C la 16,4 °C,absoarbe o caldura de 338,45J.
Alama=380 J/kg * g


Răspuns :

m=200g
ti=12⁰c
tf=16,4⁰c
Q=338,45J
c=?

c=Q/m x DT
200g=0,2kg

c=338,45j/0,2kgx4,4
c=338,45j/0,88j
c=384,6
c=Q/mxDT
200g=0,2
c=338,45J/0,2kgx4,4
c=338,45J/0,88J
c=384,6
