Which statement correctly describes the relationship between the volume of a gas and its temperature, in Kelvin, assuming pressu
re is held constant? The relationship is inversely proportional; as temperature increases, volume increases in the same way.
The relationship is inversely proportional; as temperature increases, volume increases in the same way.
The relationship is directly proportional; as temperature increases, volume increases in the same way.
The relationship is directly proportional; as temperature increases, volume increases in the same way.
The relationship is directly proportional; as temperature increases, volume decreases in the same way.
The relationship is directly proportional; as temperature increases, volume decreases in the same way.
The relationship is inversely proportional; as temperature increases, volume decreases in the same way.
The relationship is inversely proportional; as temperature increases, volume decreases in the same way.
The relationship between volume and temperature at constant pressure is expressed in this statement:
The relationship is directly proportional; as temperature increases, volume increases in the same way.
The relationship between the volume of a gas and temperature its temperature is defined by Charles Law. This law state that the volume of a given mass of gas is directly proportional to its temperature at constant pressure. It is illustrated mathematically thus:
V ∝ T or
V/T = constant
For example, if a balloon is filled with gas and placed in a cooling van, the nylon will reduce in size. But if it is heated up, the nylon will expand.
Therefore, option B correctly describes the relationship between volume and temperature at constant pressure.
Under Cyrus the Great, the Persians allowed the peoples they conquered to continue their lives and cultures. They could keep their customs and religion as long as they paid their taxes and obeyed the Persian rulers. This was different from how earlier conquerors such as the Assyrians had ruled.
