Simply put, they’re tools that let you calculate how much water your aquarium can carry, as knowing the maximum gallons of water a fish tank can hold is crucial for everyone with a fish tank, whether a newbie or expert. If you have never heard of aquarium volume calculators before, you might be wondering exactly what they are and why they exist right about now. Our calculator is super simple to use with an easily adjustable slider and offers two measurement units. If you’ve been struggling to calculate your fish tank’s volume, you will be glad to know that we have our own sleekly designed aquarium volume calculator available on this page. By pulling the plunger, the accessible volume increases, which decreases pressure and, according to Boyle's law formula, causes the suction of the fluid.Your tank's volume is approximately 0.0 cubic centimeters or 0.0 liters, which is approximately 0.0 U.S. Syringe – Whenever you have an injection, a doctor or a nurse draws a liquid from the small vial first. During exhalation, the volume of the lungs decreases, so the pressure inside is higher than outside, so the air flows in the opposite direction. As air flows from an area of higher pressure to a place of lower pressure, air enters the lungs and allows us to take in oxygen from the environment. Whenever you take a breath, your diaphragm and intercostal muscles increase the volume of your lungs, which decreases gas pressure. This model can tell us what the maximal efficiency of a heat engine is.īreathing also can be described by Boyle's law. There are a few areas where Boyle's law is applicable:Ĭarnot heat engine – Consists of four thermodynamic processes, two of which are isothermal ones, satisfying Boyle's law. You only have to ensure that the substance remains in the gas form (e.g., neither condensates nor crystallizes) at this temperature. In advanced mode, you can choose any temperature you like, and we will calculate the number of molecules contained in the gas. Boyle's law formula is valid for a wide range of temperatures. In other words, we can say that the average velocity of gas particles doesn't change during that transition. In thermodynamics, temperature measures the average kinetic energy that atoms or molecules have. You can always use our Boyle's law calculator to check if your evaluations are correct!īoyle's law describes all processes for which temperature remains constant. It is then decompressed isothermally to the pressure of 0.2 atm. The next Boyle's law example concerns a gas under 2.5 atm pressure while occupying 6 liters of space. This is a consequence of the fact that the product of the pressure and the volume must be constant during this process. P 2 = p 1 × V 1 / V 2 = 100 kPa × 2 m 3 / 1 m 3 = 200 kPa.Īfter halving the volume, the internal pressure is doubled. The question is: "How does the pressure of the gas change?". We decide to compress the box down to 1 m 3, but we don't change the overall temperature. The initial pressure is 100 kPa (or 10 5 Pa if we use scientific notation), and the volume of the container equals 2 m 3. Imagine that we have an elastic container that holds a gas. We can use Boyle's law in several ways, so let's take a look at some examples: The transition can progress in both ways, so both compression and gas expansion satisfy Boyle's law. For this process, the curve is a hyperbola. The most commonly used type is where the pressure is a volume function. We can visualize the whole process on Boyle's law graph. Just insert any three parameters, and the fourth one will be calculated immediately! This Boyle's law calculator works in any direction you like. P 2 = p 1 × V 1 / V 2 or p 2 / p 1 = V 1 / V 2.Īs we can see, the ratio of the final and initial pressure is the inverse of the ratio for volumes. Then, the equation of Boyle's law states that: Let's say we change the volume of a gas under isothermal conditions, and we want to find the resulting pressure. We can write Boyle's law formula in various ways depending on which parameter we want to estimate. Similarly, p 2 and V 2 are the final values of these gas parameters. Where p 1 and V 1 are initial pressure and volume, respectively. We can write the Boyle's law equation in the following way:
