The change of temperature in solids results in a change in their ________.
width
height
length
The equation for a change in length of a solid due to a ∆T is... ∆L=(α)(L)(∆T) α = coeff. of linear expansion (specific to material) L is the original length
The change of temperature in liquids results in a change in their ________.
weight
volume
The equation for a change in volume of a liquid due to a ∆T is... ∆V=(β)(V)(∆ T) where β = 3α β = coefficient of volume expansion (in K-¹ or °C-¹) V is original volume
