Question

the specific heat of copper metal is 0.385 j/g·c how much energy will be added to 35 g sample of copper to change temperature from 20°C to 65°C

Answer 1

Apply the formula \(\sf q=mc(t_{final}-t_{initial})\).
\(m\) is the mass, in \(\sf g\) or \(\sf kg\).
\(c\) is the specific heat, in \(\sf J/g.C\) or \(\sf J/kg.C\)
