Answer:
change in temperature = (100 - 25) = 75.0°C.
change in thermal energy = mass × specific heat capacity × change in temperature.
= 0.200 × 4,180 × 75.0.
= 62,700 J (62.7kJ)
b) by the end of the fifth day, group b will be more than one cm taller than group a. eliminate
Explanation:
The correct prediction based on the data shown is that by the end of the fifth day, group B plants will be more than 1cm taller than group A plants.
let us examine the table closely;
Day Group A (Water Only) Plant Height (cm) Group B (Water and Fertilizer)
1 2.0 2.0
2 2.2 2.3
3 2.3 2.8
4 2.5 3.2
5 2.6 3.8
We can see that by the end of the fifth day, the height differences between the two plants, 3.8 - 2.6 = 1.2cm, this is greater than 1cm. This claim from the experiment is very correct.
Other predictions are false.
