Answer: 6.65 bullfrogs per square
kilometer
Explanation:
The formula to calculate the population density will be:
= N/A
where,
N = total population = 452
A = land area = 68km²
Therefore, population density will be:
= N/A
= 452/68
= 6.65 bullfrogs per square
kilometer

Energy released from changing the phase of a
substance from the liquid phase to solid phase can be calculated by using the
latent heat of fusion. The heat of fusion of iron is calculated as follows:
<span>Energy = mL(f)</span>
<span>9840 cal (4184 J / 1 cal) = .200 kg x L(f)</span>
L(f) = 2.06 x10^8 J/kg
