The most weight was gained between 0 - 1 years for both boys and girls.
<h3>What is weight?</h3>
- Weight is a vector quantity that varies from place to place to due to effect of gravity.
Average weight of the boys in pounds;
age -------------------- average weight
0 -------------------------50
1 ------------------------- 45
2 ------------------------ 40
3 ------------------------- 35
4 -------------------------- 30
5 -------------------------- 25
Average weight of the girls in pounds;
0 --------------------------------- 20
1 ----------------------------------- 15
2 ------------------------------------ 10
3 --------------------------------------5
4 -------------------------------------- 0
5 --------------------------------------- 1

If not in use dispose it or when you need keep it from children
I’m pretty sure you would have to divide 5 and 30 and you will get 0.16666666 but I would think it would be 6cm/s but I could be wrong and if it is I’m am truly sorry.
Answer:
The change in internal energy is - 1.19 kJ
Explanation:
<u>Step 1:</u> Data given
Heat released = 3.5 kJ
Volume calorimeter = 0.200 L
Heat release results in a 7.32 °C
Temperature rise for the next experiment = 2.49 °C
<u>Step 2:</u> Calculate Ccalorimeter
Qcal = ccal * ΔT ⇒ 3.50 kJ = Ccal *7.32 °C
Ccal = 3.50 kJ /7.32 °C = 0.478 kJ/°C
<u>Step 3:</u> Calculate energy released
Qcal = 0.478 kJ/°C *2.49 °C = 1.19 kJ
<u>Step 4:</u> Calculate change in internal energy
ΔU = Q + W W = 0 (no expansion)
Qreac = -Qcal = - 1.19 kJ
ΔU = - 1.19 kJ
The change in internal energy is - 1.19 kJ
