Answer: 37.9 g
Explanation:
heat gained = heat lost
[tex]Q= m\times c\times \Delta T[/tex]
Q = heat lost by aluminium= heat gained by water= 815.7 J
m = mass of the substance = ?
c = heat capacity of aluminium = 0.897 J/gK
[tex]\Delta T={\text{Change in temperature}}=(325-301)K= 24[/tex] [tex]815.7J=m\times 0.897J/gK\times24K[/tex]
[tex]m=37.9g[/tex]
A cube of aluminum has a temperature of 325 K, if the aluminum cools to 301 K as the water absorbs 815.7 J of heat then the mass of cube is 37.9 grams.
How do we calculate the mass?
Mass of the aluminum cube will be calculated by using the below formula:
Q = mcΔT, where
Q = amount of absorbed heat = 815.7 J
m = mass of aluminum cube = ?
c = specific heat of aluminum cube = 0.897 J/g•K
ΔT = change in temperature = 325 - 301 = 24K
On putting values we get
m = 815.7 / (0.897)(24)
m = 37.9g
Hence mass of aluminum cube is 37.9 g.
