Question

What are the three main gas laws? Know how each relates to temperature, pressure and volume
(simplify answer)

Answer 1

The three main gas laws are:

1. **Boyle's Law**:
- **Relation**: Pressure and Volume
- **Description**: When the temperature is constant, the pressure of a gas is inversely proportional to its volume. If you increase the volume, the pressure decreases, and vice versa.
- **Formula**: \( P_1 V_1 = P_2 V_2 \)

2. **Charles's Law**:
- **Relation**: Volume and Temperature
- **Description**: When the pressure is constant, the volume of a gas is directly proportional to its absolute temperature (in Kelvin). If you increase the temperature, the volume increases, and vice versa.
- **Formula**: \( \frac{V_1}{T_1} = \frac{V_2}{T_2} \)

3. **Gay-Lussac's Law**:
- **Relation**: Pressure and Temperature
- **Description**: When the volume is constant, the pressure of a gas is directly proportional to its absolute temperature. If you increase the temperature, the pressure increases, and vice versa.
- **Formula**: \( \frac{P_1}{T_1} = \frac{P_2}{T_2} \)

These laws describe how temperature, pressure, and volume interact in gases under different conditions.
