____ have more energy than ____.
2 answers:
Answer : The correct option is, Infrared rays; radio waves
Explanation :
Electromagnetic waves : It is a wave in which two vectors are vibrating mutually perpendicular to each other and in direction of the wave. The two vectors are electric field and magnetic field.
The gamma-rays, x-rays, ultraviolet-rays, infrared-rays, microwaves and radio-waves are the electromagnetic waves.
The increasing order of electromagnetic waves in terms of wavelength will be,
As,
According to the formula, the energy is inversely proportional to the wavelength. That means higher the wavelength, lower will be energy and vice-versa.
The decreasing order of electromagnetic waves in terms of energy will be,
Therefore, infrared rays have more energy than radio waves.

Answer:
For a gas held at constant temperature, we can apply Boyle's law, which states that the product between the gas pressure and its volume is constant:
where
P is the pressure
V is the volume
As we see from the equation, P and V are inversely proportional to each other: this means that when the volume is decreased, the pressure increases, and vice-versa. The reason for that is that when the volume is decreased, the gas is compressed, so the molecules of the gas come closer to each other, so they collide more frequently with the wall of the container, exerting therefore a greater pressure.
