Question 38

A student investigates whether respiration in germinating seeds is exothermic. The table shows the results. Table

Flask	Contents	Temperature on day 0 in $∘C^\circ\text{C}$	Temperature on day 5 in $∘C^\circ\text{C}$
1	living germinating seeds	20.0	26.5
2	boiled seeds	20.0	20.5
What is the best estimate of the mean temperature rise per day caused by respiration in the germinating seeds, in $∘C^\circ\text{C}$ per day?
