A year has 365 days, and a day has 24 hours. If an hour has 60 minutes and a minute has 60 seconds. How many seconds are there in 2 years?

There are 60 seconds on a minute. You have to do 60 X 60 to get one hour (3600 seconds) Then, you have to get 3600 seconds and multiply it by 24 since there are 24 hours in a day (84600 seconds) Then since there are 365 days in a year you have to do 84600 X 365 and you will get 31,536,000 seconds.Explanation:

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
