The temperature of the xenon : 180.863 K
<h3>Further explanation</h3>
Combined with Boyle's law and Gay Lussac's law

P1 = initial gas pressure (N/m² or Pa)
V1 = initial gas volume (m³)
P2 = final gas pressure
V2 = finalgas volume
T1 = initial gas temperature (K)
T2 = final gas temperature
P1=251 kPa
T1=-18+273=255 K
V1=1.9 L
P2=205 kPa
V2=1.65 L

Triangles may be regarded as similar or congruent on the following basis;

What is a triangle?</h3>
A triangle is a three sided figure. The figures are not shown here. However, two triangle may be regarded as similar or congruent by the following conditions;
1) Side angle side (SAS)
2) Side side side (SSS)
3) Angle Angle side (AAS)
Since the triagles are not shown here, the similarity of the triangles can not be established.

Conductors are required to transmit electricity to various parts of the home. These take the form of the copper in the wires. Insulators separate various electrical conduits from each other and external bodies, as well as protecting the conductors from the elements. These take the form of the plastic sheathing over the wires.
