A sample of hydrogen gas (H2) was heated until its original temperature of 305 K reached 453 K. If the final volume of the sample is 5.40 L, what was the original volume?

answerleaving cheese out to get moldy;

answer;

18.5 seconds

explanation;

velocity is distance covered per unit time; it is given by displacement divided by time.

thus; time = displacement/velocity

total time = total displacement/velocity

total distance = 5000 meters south

total time = 5000/4.5

                  = 1111.11 seconds

but; 1 minute = 60 sec

thus; 1111.11 /60

                = 18.51 seconds

thus; the time taken is 18.5 seconds
