The amount of heat energy q used to heat up
WebFeb 22, 2024 · Initially, Heat released by the metal Q 1 = σAT 4. Later, Heat released by the metal Q 2 = σAT 4. As the temperature is tripled, T 2 = 3T. So Q 2 = σAT 24 = σA (3T) 4 = 81 σAT 4. Q2 = 81 Q1. So, the correct answer is option 4. An object that absorbs and emits all possible radiation with 100% is called a blackbody. WebStep 5: Using the equation Q = mL Q = m L, calculate the energy required to change the substance from its second phase to its third phase. Step 6: Using the equation Q = mcΔT Q = m c Δ T ...
