A sample of chlorine gas is held at a pressure of 1023.6 kPa. When the pressure is decreased to 8114 kPa the
eduard

Answer:

T₁  = 39 K

Explanation:

Given data:

Initial pressure = 1023.6 kpa

Final pressure = 8114 kpa

Final temperature = 36°C (36+ 273= 309K)

Initial temperature = ?

Solution:

P₁/T₁ = P₂/T₂

T₁  = P₁×T₂ /P₂

T₁  = 1023.6 kpa × 309 K /8114 kpa

T₁  = 316292.4 K. Kpa /8114 kpa

T₁  = 39 K

Thus original pressure was 39 k.

What is the reason behind that the melting and boiling point of iron is more than that of sodium?​
sweet [91]

Answer:

As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds than for covalent substances.
