Answer

The amount of thermal energy absorbed can be calculated using the formula:q = mcΔTWhere:* q = thermal energy absorbed (in Joules)* m = mass of the substance (in grams)* c = specific heat capacity of the substance (in J/g°C)* ΔT = change in temperature (in °C)Given:* m = 20.0 g* c = 0.388 J/g°C* ΔT = 30.0°C - 0.0°C = 30.0°CSubstituting the values into the formula:q = (20.0 g) * (0.388 J/g°C) * (30.0°C)q = 232.8 JTherefore, the amount of thermal energy absorbed is .
