This composer reworked his ballet Ala i Lolli into the Scythian Suite, and this composer of the Lieutenant Kije Suite styled his first symphony in D major after Haydn, calling it the "Classical Symphony."  The "Dance of the Knights" appears in this composer's ballet Romeo and Juliet. He used an oboe to represent a duck and strings to represent the title character in one tone poem, which also features the bassoon to represent a grandfather and french horns to represent the title animal. For 10 points, name this Russian composer of Peter and the Wolf.
Fine Arts

Mobility is related to the zeta potential, dielectric constant, and this quantity in the Smoluchowski equation. For gases, the variation of this quantity with temperature is given by Sutherland's formula. Measured with a Zahn cup, this quantity is squared in the Grashof number, and the ratio of this quantity to thermal diffusivity is the Prandtl number. When this quantity is zero, the Euler equations correspond to the NavierStokes equations. Reynolds number is the ratio of inertial forces to this quantity, which is constant for Newtonian fluids. Measured in poise [PWAHZ], this quantity is zero for superfluids. For 10 points, name this internal friction of a fluid that tends to resist its flow.
Science

The negative ratio of this quantity to the gas constant is equated to the derivative of the natural log of equilibrium constant over the derivative of the natural log of inverse temperature. During throttling processes, this quantity remains constant, and for isochoric processes, this quantity is simply equal to the change in internal (*) energy. The standard heat of formation is this quantity for the formation of 1 mol of a compound. This quantity for the conversion of a gas to an ionic solid is reported as the lattice energy, and this quantity has units of joules per kilogram. For 10 points, name this quantity which is equal to the product of pressure and volume of a system plus its internal energy, which is usually denoted H.
