Combined Gas Law 2.0

According to Boyle's Law, pressure and volume are inversely related which means that

• When pressure increases, volume increases
• When pressure decreases, volume decreases
• When pressure increases, volume decreases
• When pressure doubles, volume triples

According to Charles Law, volume and temperature are directly related. This means that

• When volume increases, temperature increases
• When volume increases, temperature decreases
• When volume double, pressure triples
• When volume doubles, volume is reduced by 1/2
