What happens to temperature and thermal energy during phase change​

Chemistry
1 answer:
Cloud [144]3 years ago
3 0

Answer:

During phase change (e.g. gas to liquid/liquid to solid vice versa), there is no temperature change observed. Thermal energy is not used to increase the kinetic energy of the particles, but to break the intermolecular forces. Thus, the temperature remains constant as all the thermal energy is used up and none of it is absorbed or released.

love history [14]
  • T_1=27°C
  • T_2=40°C
  • V_1=1L
  • V_2=?

Using Charles law

\boxed{\sf \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}}

\\ \sf\longmapsto V_1T_2=V_2T_1

\\ \sf\longmapsto 1(40)=27V_2

\\ \sf\longmapsto V_2=\dfrac{40}{27}

\\ \sf\longmapsto V_2=1.48\ell

Calculate the concentration of hi when the equilibrium constant is 1x10^5
exis [7]
Answer is: concentration of hydrogen iodide is 6 M.

Balanced chemical reaction: H₂(g) + I₂(g) ⇄ 2HI(g).
[H₂] = 0.04 M; equilibrium concentration of hydrogen.
[I₂] = 0.009 M; equilibrium concentration of iodine.
Keq = 1·10⁵.
Keq = [HI]² / [H₂]·[I₂].
[HI]² = [H₂]·[I₂]·Keq.
[HI]² = 0.04 M · 0.009 M · 1·10⁵.
[HI]² = 36 M².
[HI] = √36 M².
[HI] = 6 M.
