Question

How much energy is required to raise the temperature of 0.2 kg of aluminum from 15^circ C to 18^circ C ? (Refer to table of specific heat values.) A. 179J B. 600J C. 538J D. 5382J

Answer 1

To solve this problem, we need to use the formula for calculating the amount of energy required to change the temperature of a substance:Q = m × c × ΔTWhere:- Q is the amount of energy required (in joules)- m is the mass of the substance (in kilograms)- c is the specific heat capacity of the substance (in joules per kilogram per degree Celsius)- ΔT is the change in temperature (in degrees Celsius)Given information:- Mass of aluminum (m) = 0.2 kg- Initial 15°C- Final temperature = 18°C- Change in temperature (ΔT) = 18°C - 15°C = 3°CThe specific heat capacity of aluminum is approximately 900 J/kg°C.Substituting the values into the formula:Q = 0.2 kg × 900 J/kg°C × 3°CQ = 540 JTherefore, the correct answer is C. 538J.
