FAQ

What is the Volume Expansivity?
Volume Expansivity is the fractional increase in the volume of a solid, liquid, or gas per unit rise in temperature. Volume Expansivity is usually measured using the Per Degree Celsius for Temperature Coefficient of Resistance. Note that the value of Volume Expansivity is always negative.
Can the Volume Expansivity be negative?
Yes, the Volume Expansivity, measured in Temperature Coefficient of Resistance can be negative.
What unit is used to measure Volume Expansivity?
Volume Expansivity is usually measured using the Per Degree Celsius[°C⁻¹] for Temperature Coefficient of Resistance. Per Kelvin[°C⁻¹] are the few other units in which Volume Expansivity can be measured.
