The boiling point is the temperature at which a liquid turns into vapor.

The boiling point is defined as the temperature at which a liquid's vapor pressure equals the external pressure.

The melting point is the temperature at which a solid becomes a liquid.

Radiation is the transfer of heat through electromagnetic waves, such as infrared radiation.

The transition from a gas to a liquid is called condensation.

Sublimation is the process where a solid transitions directly to a gas without becoming a liquid.

Evaporation is the process of a liquid turning into gas below its boiling point.

Evaporation is the process where liquid turns into gas.

Sublimation is the process where a solid turns directly into a gas.

The upward force exerted by a fluid on a submerged object is known as buoyancy.

The upward force experienced by an object submerged in a fluid is known as buoyancy.

The term independent of x occurs when k = 7, C(7, 3) * (3)^3 * (-4)^4 = 35 * 27 * 256 = 84.

The term 'adsorption capacity' refers to the amount of solute that can be adsorbed per unit mass of adsorbent.

10 g of Na = 0.434 moles. 2Na + H2SO4 → Na2SO4 + H2. 0.434 moles of Na2SO4 = 0.434 * 142 g = 61.6 g.

23 g of Na = 1 mole. 1 mole of Na produces 1 mole of NaCl = 58.5 g.

23 g of Na = 1 mole. 1 mole of Na produces 1 mole of NaCl = 58.5 g.

Threshold frequency (ν₀) = Work function (Φ) / h = 4.5 eV / (4.14 x 10^-15 eV·s) = 5.4 x 10^14 Hz.

The threshold of hearing is defined as 0 dB, which corresponds to the faintest sound that can be heard by the average human ear.

Time period (T) = 2π/ω_n = 2π/10 = 0.2π ≈ 0.628 s.

Time period (T) = 2π/ω_n = 2π/3 rad/s = 2π/3.

The time period T of a simple pendulum is given by T = 2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity.

Torque = Force × Distance = 12 N × 0.25 m = 3 Nm.

Torque = Force × Distance = 8 N × 0.75 m = 6 Nm.

Torque = Force × Distance = 60 N × 0.75 m = 45 Nm.

Torque = Force × Distance = 60 N × 0.75 m = 45 Nm.

Torque (τ) = Force (F) × Distance (r) = 10 N × 2 m = 20 Nm.

Torque = Force × Distance × sin(θ) = 15 N × 0.5 m × sin(90°) = 15 Nm.

Torque = Force × Distance × sin(90°) = 25 N × 0.5 m × 1 = 12.5 Nm.

Using Ohm's Law, I = V / R. Here, I = 12 V / 4 ohms = 3 A.

Using Ohm's Law (I = V/R), the current is I = 12V / 4Ω = 3A.
