Briefly explain why there is a constant temperature plateau in the cooling curve

Chemistry

This plateau is where a phase change occurs. Likely, this cooling curve observes the changing of a liquid into a solid (so that the temperature is quantifiable). As something cools, it’s losing energy to the surroundings; when a phase change occurs, like liquid to solid, energy isn’t lost directly from the atom, but instead the energy maintained by free motion of the atom is used. This lack of motion reduces it into a lattice (all while maintaining a constant internal energy), finalizing the phase change, after which energy is lost directly from the atom again.

C=h/[M(T2-T1)] solve for T1
vodka [1.7K]

Explanation:

This is expressing as a subject of a formula of a specie.

This equation is used in solving for specific heat capacity of a material;

     equation:

         c = \frac{h}{M(T2 - T1)}

First cross multiply:

  c[M(T2 - T1)]  = h

Then multiply both sides by \frac{1}{c } :

\frac{1}{c }  x    c[M(T2 - T1)]   = \frac{1}{c }  x h

        M(T2 - T1) = \frac{h}{c}

Multiply both sides by \frac{1}{M}

\frac{1}{M}   x   M(T2 - T1)  = \frac{1}{M} x  \frac{h}{c}

    T2 - T1 = \frac{h}{Mc}

Now rearrange to produce;

    T1 = T2 + \frac{h}{Mc}

How to determine whether an element is paramagnetic or diamagnetic?
givi [52]
To determine whether an element is paramagnetic or diamagnetic, you need to examine the electron configuration of the element. If it has unpaired electrons, then the substance is paramagnetic. If the electrons are paired, then it is diamagnetic.

What is difference between ∆H and ∆H°
Elena-2011 [213]

If it is shown as ∆H , then it means that a specific chemical reaction is undergoing heat in Kelvin(K). If it is shown as ∆H° , then it means that a specific chemical reaction is undergoing heat in Celsius(C⁰).
