Explanation:
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
Answer:
0.900 Jg^-1℃^-1
Explanation:
Given that;
H = mcθ
H = heat added
m = mass of aluminium
c = specific heat of aluminum
θ = increase in temperature
Making c the subject of the formula;
c = H/mθ
c = 207 J/28.4 g * 8.1oC
c = 0.900 Jg^-1℃^-1
