Study Notes: SAT Physics Subject Test

Heat and Thermodynamics

Temperature scales: \small T(K)=T(^{\circ}C)+273

Temperature change: \small Q=mc \Delta T (c is the specific heat.)

Phase change: \small Q=mL (L is the latent heat of transformation.)

Thermal expansion

\small \Delta L = \alpha L_{0} \Delta T (\small \alpha is the coefficient of linear expansion.)

\small \Delta V = \beta V_{0} \Delta T (\small \beta is the coefficient of volume expansion.)
