Abike tire reads a pressure of 13.2 psi. what is the
pressure of this bike tire in atm? (recall: 1 atm = 14.7 psi)
don't forget to express your answer with the correct
number of significant figures. *

0.89821 atm

Explanation:

Psi and atm are units of pressure.

Psi stands for pound force per square inch.

While atm stands for atmosphere.

In order to convert the psi to atm we would divide the given value 14.696.

Given value = 13.2 psi

In atm:

13.2 / 14.696 = 0.89821 atm

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
