Frictional force is directly proportional to the normal force. Increasing the normal force increases the frictional force.

Increasing the number of alkyl substituents on the double bond increases the stability of alkenes due to hyperconjugation.

As the number of carbon atoms increases, the acidity generally decreases due to the increasing electron-donating effect of alkyl groups.

As the number of carbon atoms increases, the solubility of carboxylic acids in water generally decreases due to the increasing hydrophobic character.

The boiling points of alcohols increase with the number of carbon atoms due to increased van der Waals forces.

The boiling points of aldehydes increase with the number of carbon atoms due to increased van der Waals forces.

Increasing the number of gas molecules at constant temperature and volume leads to more collisions with the walls of the container, resulting in increased pressure.

Increasing the number of gas molecules at constant volume and temperature increases the pressure, according to the ideal gas law.

The RMS speed is independent of the number of gas molecules; it depends only on temperature and molar mass.

According to the ideal gas law, increasing the number of moles (n) of a gas while keeping volume (V) and temperature (T) constant will increase the pressure (P).

According to Avogadro's Law, increasing the number of moles of gas increases the pressure if the volume is constant.

According to Avogadro's Law, increasing the number of moles of gas increases the pressure if temperature and volume are constant.

According to the ideal gas law, increasing the number of moles of gas at constant volume and temperature will increase the pressure.

According to Avogadro's Law, increasing the number of moles of gas at constant volume and temperature will increase the pressure.

According to Avogadro's Law, increasing the number of moles of gas increases the pressure if volume and temperature are constant.

Increasing the number of slits in a diffraction grating results in sharper maxima due to increased constructive interference.

Increasing the number of turns in a coil increases its inductance.

Increasing the number of turns (N) in a coil increases the induced EMF, as EMF = -N * (dΦ/dt).

According to Faraday's law, the induced EMF is directly proportional to the number of turns in the coil. Therefore, increasing the number of turns increases the induced EMF.

According to Faraday's law of electromagnetic induction, the induced EMF is proportional to the rate of change of magnetic flux and the number of turns in the coil. Increasing the number of turns increases the induced EMF.

Increasing the number of turns in a coil increases the magnetic field produced, as the field is proportional to the number of turns.

Increasing the number of turns increases the magnetic field strength.

Increasing the number of turns (n) in a solenoid increases the magnetic field strength, as B = μ₀nI.

The magnetic field inside a solenoid is directly proportional to the number of turns per unit length. Increasing the number of turns increases the magnetic field strength.

As the object distance increases, the size of the image formed by a convex lens increases until it reaches a maximum.

Increasing the permittivity of the medium decreases the electric field due to a point charge, as E = Q/(4πε₀r²).

Increasing the plate area A of a capacitor increases its capacitance, as C is directly proportional to A.

Increasing the plate area A of a parallel plate capacitor increases its capacitance, as C = ε₀ * A / d.

At constant temperature, increasing pressure does not affect the RMS speed, as it is dependent on temperature and molar mass.

At constant volume, increasing pressure increases the temperature of the gas, which in turn increases the RMS speed.
