Solution:

To calculate the mass increase, we must go through the following steps:
→ Calculate the heat energy supplied
→ Calculate mass increase according to Einstein

1. Q = m·c_w·ΔT
2. Q = 1000kg · 4,18 kJ/kg · 50 ℃
3. Q = 2.09·10⁸ J
4. ΔE=Δm·c² or Δm = ΔE/c²
5. Δm = 2.09·10⁸ [kg·m²/s²]/(300'000'000 m/s)² = 2.32·10^-9 kg
