Answer:
2.6 kJ
Explanation:
The formula for the amount of heat (q) absorbed by the water is
q = mCΔT
1. Calculate ΔT
ΔT = 23.5 °C - 22.1 °C = 1.4 °C
2. Calculate q
q₂ = mCΔT = 500 g × 4.184 J·°C⁻¹g⁻¹ × 1.4 °C = 2900 J = 2.9 kJ

Answer:
state of matter
Explanation:
Because there are three state of matter namely:liquid,solid and gas and oxygen is a gas.
D = m / V
0.736 = 225.0 / V
V = 225.0 / 0.736
V = 305.7 cm³
