The work done by a gas during expansion at constant pressure is given by W = PΔV.

During isothermal expansion, the work done by the gas is equal to the heat absorbed, as the internal energy remains constant.

The work done by an ideal gas during an isobaric process is given by W = PΔV.

The work done by an ideal gas during an isothermal expansion is W = nRT ln(Vf/Vi).

The work done by an ideal gas during an isothermal expansion is given by W = nRT ln(Vf/Vi).

Frictional force F_friction = μk * N = 0.4 * 5 kg * 9.8 m/s² = 19.6 N. Work done by friction = -F_friction * distance = -19.6 N * 2 m = -39.2 N·m, approximately -40 N·m.

In an isochoric process, the volume remains constant, so no work is done by the system (W = PΔV = 0).

In an isochoric process, the volume remains constant, so no work is done by the system (W = PΔV = 0).

The work done by the system during expansion against a constant external pressure is given by W = PΔV.

Work done W = F * d = q * E * d = (2 × 10^-6 C) * (500 N/C) * (0.4 m) = 0.4 J = 80 J.

W = q * V = 2 × 10^-6 C * 10 V = 20 × 10^-6 J = 20 μJ.

Work done W = q * V = (2 × 10^-6 C) * (5 V) = 10 μJ.

Work done W = q * ΔV = 2 × 10^-6 C * (100 V - 50 V) = 2 × 10^-6 * 50 = 0.1 mJ.

Work done W = q * ΔV = (2 × 10^-6 C) * (100 V - 50 V) = 100 μJ.

The work done is equal to the change in gravitational potential energy, which depends on the initial and final positions.

The work done in moving an object in a uniform gravitational field depends only on the height difference between points A and B.

The work done in moving an object in a gravitational field depends only on the initial and final positions, not the path taken.

In an isochoric process, the volume remains constant, which means no work is done on or by the gas. Therefore, the work done is zero.

The work function φ can be calculated using φ = hf, where h = 6.63 x 10^-34 J.s and f = 5 x 10^14 Hz, giving φ ≈ 3.1 eV.

The work function is the minimum energy required to remove an electron from the surface of a metal.

The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy.

To find the x-intercept, set y = 0. Thus, 3x - 12 = 0 gives x = 4.

Setting x = 0 in the equation gives 2y - 10 = 0, thus y = 5.

Set x = 0: 2y = 10 => y = 5. The y-intercept is (0, 5).

Capillarity is the phenomenon where liquid rises in a narrow tube due to surface tension.

Enzymes are proteins that act as catalysts, speeding up biochemical reactions without being consumed in the process.

Chemisorption is characterized by the formation of strong chemical bonds between the adsorbate and the adsorbent.

Chemisorption involves the formation of strong chemical bonds between the adsorbate and the adsorbent.

Isopropanol (2-propanol) is a secondary alcohol, as the hydroxyl group is attached to a carbon that is connected to two other carbons.

Enzymes are primarily proteins that catalyze biochemical reactions.
