In an electric circuit, the volt (V) does the work by providing the electrical potential difference that drives current through the circuit, described mathematically as $V = I \cdot R$.

Energy can be removed from matter by increasing its volume, lowering its temperature, increasing its pressure, or boiling it, using formulas such as $PV = nRT$, $Q = mc\Delta T$, $PV^\gamma = \text{constant}$, and $Q = mL_v$.

A simple electric motor transforms electrical energy into mechanical energy through electromagnetic interactions, where current through coils generates a magnetic field that produces torque, leading to rotor motion.

Energy is expended in active transport through the hydrolysis of ATP to ADP and Pi, which provides the necessary energy to move molecules against their concentration gradient.

Activation energy provides enough energy for reactants to form the transition state, as described by the Arrhenius equation:

Energy in the Sun's core is transferred outward through radiative diffusion in the inner regions, described by $\frac{\partial I}{\partial t} + c \mathbf{n} \cdot \nabla I = j - \alpha I$, and convective transfer in the outer layers, following $q = h_c A \Delta T$.

$\text{Ar} > \text{Cl} > \text{P} > \text{Si} > \text{Mg} > \text{AI} > \text{Na}$ reflecting the trend in first ionization energy.

The only whole numbers that multiply to equal 11 are $1 \times 11$ and $11 \times 1$, though any nonzero real number $x$ and its counterpart $\frac{11}{x}$ will also work.
