What is the relationship between the variables on this graph? As the temperature increases, the flow rate increases.

The temperature does not have an effect on flow rate.

As the temperature increases, the flow rate decreases.

Ithinks its false. tell me if im wrong

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.
