In this problem, the ideal gas equation PV=nRT is applied. In this relationship, volume is inversely proportional to pressure. Hence, pressure increases when volume decreases, vice versa. In this case, volume is decreased from 75 to 50 L, so the pressure is expected to increase above 300 kilopascals.
Answer:
During World War II, rationing was implemented to control the equal distribution of items in short supply. Although the primary goal of rationing was equal distribution, a secondary goal was to free valuable factory resources for war production.

A
Explanation:
The earth's rotation makes stars appear to move during the night.
Answer:
The energy of electromagnetic radiation increases as its frequency increases.
The frequency and wavelength of electromagnetic radiation are inversely proportional.
Explanation:
According to Max Plank's equation, the energy of electromagnetic radiation is given by E=hf where h= Plank's constant and f= frequency of the electromagnetic radiation. This means that the energy and frequency of electromagnetic radiation and its energy are related by a direct proportion. As frequency of the electromagnetic radiation increases, the energy of the radiation increases also.
However, frequency and wavelength of electromagnetic radiation are inversely related. The frequency decreases with increasing wavelength of electromagnetic radiation.
