The equation relating the volume change to a change in temperature has the same form as the linear expansion equation, and is given by the formula ĭelta V = beta V_0 Delta T or V_f=V_0(1+beta Delta T )ĭV = V_1-V_0 = change in volume (m^3) īeta = volumetric temperature expansion coefficient (m^3/m^3^oC) Specific volume of a unit can be expressed as Where Delta V is the change in volume in m^3, beta is the coefficient of volume expansion in ^o C ^- ^1, V_0 is the original volume in m^3, Delta T is the temperature change in ^o C. ![]() It is always a good idea to asses in a given situation, but, comparing the two coefficients of thermal expansion for the liquid and solid involved gives different analysis and study. Sometimes it is being neglected the expansion or contraction of the container because liquids usually have a significantly and substantially higher coefficient of thermal expansion than do solids. In other cases, like for a mercury or alcohol-filled thermometer, it is the variation in volume that is significant. In some instancesit is just an amendment in one dimension that really matters. When something alters temperature, it increases or decreases in all three dimensions. ![]() It depends in the change in temperature, fundamental volume, and the kind of substance. Volume expansion takes placein liquids and gases.
