The specific heat of copper is 0.092 cal/g·°C. How much energy is required to heat 40.0 grams of copper from 25.0°C to 75.0°C? A)92 cal B)184 cal C)2.0 × 10² cal D)280 cal

Question

Quizplus · Accepted Answer

The energy required can be calculated using the formula: Q = mcΔT, where m = 40.0 g, c = 0.092 cal/g·°C, and ΔT = 75.0°C - 25.0°C = 50.0°C. Thus, Q = 40.0 g × 0.092 cal/g·°C × 50.0°C = 184 cal.
