Answer:
8 cm3
Explanation:
The volume of this irregular solid will calculated as the difference between the final volume and the initial volume;
The final volume of the water and the solid is 25 ml
The initial volume of the water alone was 17 ml
The volume of the irregular solid is thus approximately;
25 - 17 = 8 ml
We then use the conversion;
1 cm3 = 1 mL
Thus the volume of the solid is 8 cm3

Answer: 1,013.32 cal × 4.18 J/cal = 4,235.68 J
Explanation:
1) Data:
Water ⇒ C = 1 cal/g°C
m = 65.8 g
Ti = 31.5°C
Tf = 36.9°C
Heat, Q = ?
2) Formula:
Q = mCΔT
3) Calculations:
Q = 65.8g × 1 cal/g°C × (46.9°C - 31.5°C) = 1,013.2 cal
4) You can convert from calories to Joules using the conversion factor:
1 cal = 4.18 J
⇒ 1,013.32 cal × 4.18 J/cal = 4,235.68 J
