oblicz energie potrzebna do stopienia wzkazanej masy lodu:
a) 6,17g
b) 15 dag
c)180mg
d)16,9g
e)28g
L=ciepło topnienia lodu
L= 335 000 J/kg
a]
m=6,17g=0,00617kg
Q=mL=0,00617kg*335 000 J/kg= 2066,95 J
b]
m=15dag=150g=0,15kg
Q=0,15kg*335 000 J/kg=50 250 J
c]
m=180mg=0,18g=0,00018kg
Q=0,00018kg*335 000 J/kg=60,3J
d]
m=16,9g=0,0169kg
Q=0,0169kg*335 000J/kg=5661,5J
e]
m,=28g=0,028kg
Q=0,028*335 000J/kg=9380J
