The statement above is TRUE.
When heat is added to a substance, the heat increases the kinetic energy of the particles of the substance and enable to vibrate or move faster, this usually increase the temperature of the substance. However, adding heat does not always increase the temperature of a substance. For instance, during the process of boiling point of water, the additional heat energy that is added to the water is used to break the chemical bonds in water and not to increase the temperature of water.<span />
B) decreasing the reactants particle size
1) pOH(solution) = 6.
pOH + pH = 14.
pH = 14 - pOH.
pH = 14 - 6.
pH = 8.
pH (potential of
hydrogen) is a numeric scale used to specify the acidity or basicity <span>an aqueous solution.
This solution is basic, because pH value is greater than 7.
</span>2) [OH⁻] = 10∧(-pOH).
[OH⁻] = 10⁻⁶ M; equilibrium concentration of hydroxide ions.
You can use the HWE (Hardy Weinberg Equilibrium) equations :
p + q = 1
p^2 + 2pq + q^2 = 1
If the allele combinations do not equal one after a while, evolution has occurred.
