Answer 2

Calculating Heat Required to Heat Water in an Aluminum Tank

To calculate the amount of heat required to heat 10 liters of water from 20 to 100 degrees Celsius in an aluminum tank with a mass of 1 kg, we can use the formula:

Q = mcΔT

Where: - Q = heat energy (in joules) - m = mass of the substance (in kg) - c = specific heat capacity of the substance (in J/kg°C) - ΔT = change in temperature (in °C)

Given: - m = 1 kg - c = 4.2 J/g°C (specific heat capacity of water)

We can calculate the heat required using the formula:

Q = mcΔT

Substituting the given values: Q = (1 kg) * (4.2 J/g°C) * (100°C - 20°C)

Q = 1 kg * 4.2 J/g°C * 80°C

Q = 336 J/g°C * 1 kg * 80°C

Q = 26880 J

So, the amount of heat required to heat 10 liters of water from 20 to 100 degrees Celsius in an aluminum tank with a mass of 1 kg is 26880 joules.
