What was the initial temperature of a gas contained in a 2.0-l bottle at a pressure of 1.00 atm if it was placed under vacuum and its pressure was reduced to 0.82 atm at a temperature of 10.0 c? assume volume remains the same.

answer; natural resources;

the answers would be

the first one and the second one

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
