Aproton is also known as this ion __

Explanation:

An atom consists of three subatomic particles, that is, protons, neutrons and electrons. Nucleus of an atom consists of protons and neutrons whereas electrons revolve around the nucleus.

Protons are positively charged whereas neutrons have no charge and electrons are negatively charged.

Thus, we can conclude that a proton is also known as positively charged ion.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
