When we write length as 3.2 cm, it means that the measurement has only 2 significant figures and the length has been measured by measuring instrument having a least count if 0.1 cm. However, when we write the length as 3.200 cm, it means that the measurement has 4 significant figures i.e, the measurRead more
When we write length as 3.2 cm, it means that the measurement has only 2 significant figures and the length has been measured by measuring instrument having a least count if 0.1 cm. However, when we write the length as 3.200 cm, it means that the measurement has 4 significant figures i.e, the measurement has been done using an instrument having a least count of 0.001 cm. Thus, the second measurement is more precise.
Under high pressure and low temperature condition, the volume of a given mass of a gas is very small and molecules are closely packed. As a result, the intermolecular interactive forces become significant and cannot be neglected. Moreover as compared to total volume the actual volume occupied by theRead more
Under high pressure and low temperature condition, the volume of a given mass of a gas is very small and molecules are closely packed. As a result, the intermolecular interactive forces become significant and cannot be neglected. Moreover as compared to total volume the actual volume occupied by the gas molecules is also not negligible. Due to these two factors gases show large deviation from ideal gas behaviour under high pressure and low temperature condition.
What is the difference in writing a length as 3.2 cm and 3.2000 cm?
