The volumetric expansion can be calculated using equation (2)ĭV = (30 gallons) (0.00039 1/ o F) ((100 o F) - (70 o F))ģ0 gallons + 0.351 gallon = 30.351 gallonsĭensities of solids, liquids and gases. The volumetric expansion can be calculated using equation (2)ĭV = (0.1 m 3 ) (0.00070 1/ oC) ((40 oC) - (20 oC))ġ00 liters + 1.4 liters = 101.4 liters Example - Cubic Expansion of Oilģ0 US gallons of oil is heated from 7 0 o F to 100 o F. Volumetric expansion coefficients for commonly used liquidsĬonvert between Metric and Imperial Volumentric Temperature Coefficientsġ00 liters - 0.1 m 3 - of oil with volumetric expansion coefficient 0.00070 1/ oC is heated from 20 oC to 40 oC. Volumetric Temperature Coefficients - β - for some Fluids Density of Ethylene Glycol based Water Solution.Ρ 0 - initial density (kg/m 3, lb/ft 3 ) This calculator can be used to calculate expansion volume when initial volume and initial and final densities for the liquid are known Online Thermal Cubic Expansion Calculator - Densities The volumetric coefficient for water is negative below 4 oC and indicates that the a volume decreases when temperature moves from 0 oC ( 32 o F ) to 4 oC. Water has its highest density and smallest volume at 4 oC (39.2 o F). Example - water is a liquid where the volumetric expansion coefficient changes a lot with temperature. If you want to calculate volumetric change for a liquid over a temperature range where the volumetric expansion coefficient for the liquid changes a lot - interpolate the coefficient values, or split the calculation in the different temperature ranges. Note that the volumetric expansion coefficient used in the calculator is constant. Make a Shortcut to this Calculator on Your Home Screen?.Β - volumetric temperature expansion coefficient (1/ oC, 1/ o F) V 0 - initial volume (m 3, ft 3, gallons. The calculator below is generic and can be used for metric and imperial units as long as the use of units is consistent. Online Thermal Cubic Expansion Calculator - Expansion coefficient and Temperaturesīe aware that the expansion coefficient for some liquids - like water - may vary with temperature. Ρ 0 = initial density (kg/m 3, lb/ft 3 ) The density of a fluid when temperature changes can be expressed as Β = volumetric temperature expansion coefficient (m 3 /m 3 o C, ft 3 /ft 3 o F) The change in the units volume when temperature changes can be expressed asĭV = V 1 - V 0 = change in volume (m 3, ft 3 ) extension ideas/prompting questions for teachers.Specific volume of a unit can be expressed as.offer simple explanations of how climate change may impact the oceans’ chemical and physical properties.ĭownload the Word file (see link below) for:.describe how salinity affects water density.describe how temperature affects water density.Learn more in the article Climate change, melting ice and sea level rise.īy the end of this activity, students should be able to: Melting land ice and increased rainfall – as consequences of climate change – have the potential to disrupt the oceans’ chemical and physical properties, which will impact this complex circulation system. Both types of currents work with the atmosphere to help shape the Earth’s climate. Deeper currents are driven by changes in water density. Surface currents in the top 400 m are driven mainly by wind. It moves water, heat, salt and nutrients around the world. The ocean has a complex circulation system called the Global Ocean Conveyor.
