Answer 2

Calculating the Amount of Heat Released During Condensation

To calculate the amount of heat released during the condensation of 1.5 tons of water vapor at 100 degrees Celsius to cooled water at 10 degrees Celsius, we can use the formula:

Q = m * L + m * c * ΔT

Where: - Q = amount of heat released - m = mass of the substance (in this case, water) - L = latent heat of condensation - c = specific heat capacity - ΔT = change in temperature

Given: - m = 1.5 tons = 1500 kg - ΔT = 100°C - 10°C = 90°C - L = 2 MJ/kg = 2,000,000 J/kg - c = 4200 J/kg°C

Plugging these values into the formula:

Q = (1500 kg * 2,000,000 J/kg) + (1500 kg * 4200 J/kg°C * 90°C)

Calculating: Q = (3,000,000,000 J) + (567,000,000 J) Q = 3,567,000,000 J

So, the amount of heat released during the condensation is 3,567,000,000 joules.
