Determine the amount of thermal energy that must be transferred to a copper wire (mass 20g) to
increase its temperature from 25.0°C to its melting point (1085.0 °C). Note: The specific heat of
copper is 385 J/Kg. C.


Sagot :

Answer:  Thermal energy is 8,2 kJ

Explanation:  Heat Q = m c ΔT .    c = 385 J/kg C  and

ΔT = (1085 - 25)C = 1060 C.   Q = 0.020 kg · 385 J / (kg C) ·1060 C

= 8162 J
