Table 2 shows the time taken for blood to clot at different temperatures.
Temperature / °C: 5, 15, 25, 35, 45
Time for blood to clot / s: 70, 50, 30, 18, 32
Which statement best describes the relationship between temperature and clotting time from 5 °C to 35 °C?
Temperature / °C: 5, 15, 25, 35, 45
Time for blood to clot / s: 70, 50, 30, 18, 32
Which statement best describes the relationship between temperature and clotting time from 5 °C to 35 °C?
- As temperature increases, clotting time decreases, so blood clots faster up to 35 °C.
- As temperature increases, clotting time increases, so blood clots slower up to 35 °C.
- Clotting time stays the same as temperature increases up to 35 °C.
- Clotting time first decreases then increases between 5 °C and 35 °C.
