Pemuaian
Pemuaian Panjang
\(\Delta L = \alpha \:.\: L_o \:.\: \Delta T\)
\(L_t = L_o \:.\: (1 \pm \alpha \:.\: \Delta T)\)
\(\alpha\) = koefisien muai panjang
\(\Delta T\) = perubahan suhu
\(\Delta L\) = perubahan panjang
\(L_o\) = panjang mula-mula
\(L_t\) = panjang akhir
Pemuaian Luas
\(\Delta A = \beta \:.\: A_o \:.\: \Delta T\)
\(A_t = A_o \:.\: (1 \pm \beta \:.\: \Delta T)\)
\(\beta\) = koefisien muai luas = \(2 \times \alpha\)
\(\Delta T\) = perubahan suhu
\(\Delta A\) = perubahan luas
\(A_o\) = luas mula-mula
\(A_t\) = luas akhir
Pemuaian Volume
\(\Delta V = \gamma \:.\: V_o \:.\: \Delta T\)
\(V_t = V_o \:.\: (1 \pm \gamma \:.\: \Delta T)\)
\(\gamma\) = koefisien muai volume = \(3 \times \alpha\)
\(\Delta T\) = perubahan suhu
\(\Delta V\) = perubahan volume
\(V_o\) = volume mula-mula
\(V_t\) = volume akhir
Khusus untuk gas, nilai \(\gamma = \dfrac {1}{273}\)
Perbandingan koefisien muai:
\(\alpha : \beta : \gamma = 1 : 2 : 3\)
