We use the formula:
ΔP = (ΔH / ΔV) ln(T2 / T1)
where,
ΔH = change in enthalpy from solid to liquid = 4810 J/mol
ΔV = change in volume from solid to liquid = 0.55 cm^3/mol
T2 = 620 K, T1 = 600 K
So,
ΔP = (4810 / 0.55) ln(620 / 600)
ΔP = 286.76 J/cm^3
or converting to atm:
<span>ΔP
= 2830 atm</span>
Answer:
Explanation:
Electron capture is a form of beta decay in which the nucleus of a radionuclide captures an electron. In the case of mercury-201, the equation below illustrates that
²⁰¹₈₀Hg + ⁰₋₁e ⇒ ²⁰¹₇₉Au
As can be seen above, the electron capture reduces the atomic number by one unit leading to the production of a new radioisotope (because of the change in atomic number).
Answer:
The coldest temperature possible
Explanation:
Absolute zero = 0 K
A. is wrong. 0 °C = 273 K
B. is wrong. -210 °C = 63 K
C. is wrong. 32 °F = 273 K
E. is wrong. -196°C = 77 K
