You just throw them on the pan with the flame all the way up it will be done in a second !
The formula for energy or enthalpy is:
E = m Cp (T2 – T1)
where E is energy = 63 J, m is mass = 8 g, Cp is the
specific heat, T is temperature
63 J = 8 g * Cp * (340 K – 314 K)
<span>Cp = 0.3 J / g K</span>
<span>a pure substance that can be separated into different elements by chemical means</span>
