At a constant pressure, the density of a certain amount of an ideal gas is ____________.
At a constant pressure, the density of a certain amount of an ideal gas is inversely proportional to the temperature. Explanation: The density of an ideal gas is given as d = `"PM"/"RT"` ∴ `"d" ∝ 1/"T"` ......(∵ P, M, R = constant) Concept: Ideal Gas Equation Is there an error in this question or solution? Answer VerifiedHint:To find the relation between density, pressure and temperature, try to think logically what will happen to the density when pressure or temperature will increase.The ideal gas law, also known as the general gas equation is an equation of state of a hypothetical ideal gas. Although the ideal gas law has several limitations, it is a good approximation of the behaviour of many gases under many conditions. Complete step by step answer: Hence, the correct answer is option B. Note:This is generally the case that as temperature increases density decreases but there is one exception to this which is water. When the temperature of water is decreased, its density increases(the water contracts) but this behaviour is upto \[{{4}^{\circ }}\] celsius only. After \[{{4}^{\circ }}\] celsius, if we further decrease the temperature, its density decreases(the water expands) and this behaviour of water is called anomalous expansion of water. |
