熱量の保存 (conservation of heat quantity)
$$
m_1 c_1 (T_1 – T) = m_2 c_2 (T – T_2)
$$
m_1 c_1 (T_1 – T) = m_2 c_2 (T – T_2)
$$
m_1 c_1 (T_1 – T) = m_2 c_2 (T – T_2)

$$
\Delta U = Q + W
$$
\Delta U = Q + W
$$
\Delta U = Q + W

$$
\frac{pV}{T} = \text{const.}
熱効率 (thermal efficiency)
$$
e = \frac{W’}{Q_1} = \frac{Q_1 – Q_2}{Q_1}
$$
