<h2>Answer:</h2>
<em>Metals are both good heat conductors and good electrical conductors because of the </em><em>looseness of outer electrons in metal atoms</em>
_________________________
Unlike nonmetals that are insulators, most metals are both good heat conductors and good electrical conductors. This is because within a solid metal there is one or more outer electrons in each atom that become detached and can move freely through the solid metal, but <em>what about the other electrons?</em> Well, the
y remain bound to the positively charged nuclei, and bound within the material in almost fixed positions. On the other hand, insulators are material having few, very few or no electrons that are allowed to move freely through the material.
Answer : The correct option is, (B) 279.2 Kpa
Solution : Given,
Initial pressure of gas = 475 Kpa
Initial volume of gas = 
Final volume of gas = 
Initial temperature of gas = 290 K
Final temperature of gas = 277 K
Using ideal gas equation :
Formula used :
where,
= initial pressure of gas
= final pressure of gas
= initial volume of gas
= final volume of gas
= initial temperature of gas
= final temperature of gas
Now put all the given values in the above formula, we get the final pressure of the gas.
Therefore, the absolute pressure of the gas after expansion is, 279.2 Kpa
