To calculate the amount of heat required to raise the temperature of the copper bowl and water to the boiling point, we need to consider the following steps:

Calculate the heat required to raise the temperature of the copper bowl from 20°C to its boiling point:

q_copper = m_copper x c_copper x ΔT_copper
q_copper = 2 kg x 0.587 J/g°C x (100°C - 20°C)
q_copper = 2 kg x 0.587 J/g°C x 80°C
q_copper = 93.92 J

Calculate the heat required to raise the temperature of the water from 20°C to its boiling point:

q_water = m_water x c_water x ΔT_water
q_water = 4 kg x 4.18 J/g°C x (100°C - 20°C)
q_water = 4 kg x 4.18 J/g°C x 80°C
q_water = 1334.4 J

Total heat required to raise the temperature of the copper bowl and water to their boiling point:

Total heat = q_copper + q_water
Total heat = 93.92 J + 1334.4 J
Total heat = 1428.32 J
Therefore, the amount of heat required to introduce into the system until the copper bowl and water reaches its boiling point is 1428.32 Joules.
