A wavelength's frequency and energy (E) drop as it becomes longer. You may conclude from these equations that the wavelength grows shorter as the frequency rises. The wavelength lengthens as the frequency drops.
Since frequency and wavelength are inversely related to one another, the wavelength of the wave falls as frequency increases.
<span>While explaining the differences between the rate law and integrated rate law of the reaction, two statements apply from the options. They are
1. The rate law shows the relationship between the rate of a reaction and the concentrations of the reactants. This will give us an idea about the speed that reactants are turned to compounds and products.
2. The integrated rate law is a relationship between the concentration of a reactant and time. This gives an idea of amount of reactant left after a period of time.</span>
Below are the choices:
A The mercury will change temperature at a much faster rate under the same heating conditions.
<span>B The two metal samples will change temperature at about the same rate. </span>
<span>C The gold would float if placed in the mercury. </span>
<span>D The gold would sink to the bottom if placed in the mercury.
</span>
<span>a = false, it will take 0.031 cal to raise 1g Au 1degree while it will take 0.033 cal to raise 1g Hg 1 degree so, although Au will heat up faster, it will not be discernably faster so...
b = true
c = false, Au density > Hg
d = true</span>
