$PV = nRT$

Relates pressure, volume, and temperature of an ideal gas.

Heat Transfer

$Q = mc\Delta T$

Sensible heat transfer.

Heating Energy

The energy required to heat a substance is calculated using:

$q = c_p \cdot m \cdot \Delta T$

Where:

$q$ is the heat energy required (kJ)
$c_p$ is the specific heat capacity (kJ/kg·K)
$m$ is the mass (kg)
$\Delta T$ is the temperature change (K or °C)

Example Calculation:
Heating 10 kg of bronze ( $c_p = 0.435$ kJ/kg·K) from 20°C to 100°C ( $\Delta T = 80$ K):

$q = (0.435\ \text{kJ/kg·K}) \times (10\ \text{kg}) \times (80\ \text{K}) = 348\ \text{kJ}$
