The electric field due to a charged plane sheet is directly proportional to the surface charge density; increasing σ increases E.

Increasing surface roughness generally increases the coefficient of friction due to greater interlocking between the surfaces.

Generally, the resistance of a conductor increases with an increase in temperature.

Increasing the temperature of a gas at constant volume results in an increase in pressure, according to Gay-Lussac's law.

Increasing the temperature of a gas at constant volume increases the pressure, as per Gay-Lussac's law.

The speed of sound in a gas increases with an increase in temperature.

Increasing the temperature increases the average kinetic energy of gas molecules, which in turn increases their average speed.

For most liquids, increasing the temperature decreases the density as the liquid expands.

Increasing the temperature increases the average kinetic energy of the molecules, resulting in a wider distribution of molecular speeds.

For an endothermic reaction, increasing the temperature shifts the equilibrium to the right, thus increasing the value of Kc.

Increasing the temperature of an exothermic reaction decreases the equilibrium constant.

Generally, as temperature increases, the refractive index of a medium decreases due to reduced density.

Increasing the temperature of a conductor generally increases its resistance due to increased atomic vibrations.

Increasing the temperature generally increases the resistance of the potentiometer wire due to the increased vibrations of the atoms in the conductor.

Increasing the temperature increases the RMS speed, as v_rms is proportional to the square root of temperature.

For most solid solutes, increasing the temperature increases their solubility in water.

Increasing the temperature of a gas increases the average kinetic energy of the molecules, which in turn increases their speed.

Increasing the tension in a string increases the speed of the wave, as speed is proportional to the square root of tension.

Increasing the tension in a string increases the speed of the wave traveling through it, as speed is proportional to the square root of tension.

Increasing the transmission power generally increases the range of the communication system.

Increasing the voltage while keeping resistance constant will increase the current.

Increasing the voltage in a circuit increases the current, according to Ohm's Law.

Increasing the wavelength decreases the frequency of the incident light, which can lead to fewer or no electrons being emitted if the frequency falls below the threshold frequency.

Increasing the wavelength decreases the frequency, which may fall below the threshold frequency, thus decreasing or stopping the current.

Increasing the wavelength of light increases the fringe spacing in a diffraction grating experiment.

Increasing the wavelength of light increases the fringe spacing in a diffraction pattern.

Increasing the wavelength increases the fringe separation, as it is directly proportional to the wavelength.

Increasing the wavelength (λ) increases the fringe width (β), as β is directly proportional to λ.

Fringe separation is directly proportional to the wavelength; increasing the wavelength increases the fringe separation.

Increasing the wavelength of light decreases the angle of refraction when passing from air into glass due to the dispersion of light.
