An electric hand mixer draws $1\mathrm{.}5$ amperes at $110$ volts. It is used to mix $1kg$ of cookie dough for $5$ minutes. After mixing, the

temperature of the cookie dough is found to have increased by $6C.$ If the heat capacity of the dough is $4\mathrm{.}2kJ*k{g}^{-1}*K^{-1},$ what fraction

of the electrical energy used by the mixer is converted to internal energy of the dough?

$\%$ of the electrical energy used by the mixer is converted to internal energy of the dough.

Discuss the fate of the remainder of the energy.
