Who discovered that the volume of gas decreases?
Robert Boyle
Known for his law of gases, Boyle was a 17th-century pioneer of modern chemistry. Every general-chemistry student learns of Robert Boyle (1627–1691) as the person who discovered that the volume of a gas decreases with increasing pressure and vice versa—the famous Boyle’s law.
Who said that when you increase temperature of a gas the volume of the gas increases?
Figure 11.9. 1: As a container of confined gas is heated, its molecules increase in kinetic energy and push the movable piston outward, resulting in an increase in volume. As with Boyle’s Law, k is constant only for a given gas sample….Charles’s Law.
| Temperature (K) | Volume (mL) | |
|---|---|---|
| 300 | 120 | 0.40 |
| 500 | 200 | 0.40 |
| 1000 | 400 | 0.40 |
Which statement is correct with Boyle’s law?
A modern statement of Boyle’s law is: The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system.

How did Robert Boyle discover his law?
Using Hooke’s pump, Boyle and Hooke carried out experiments to investigate the properties of air and the vacuum, making their first great discovery: Boyle’s Law. They made their discovery using a glass tube similar to the one shown at the top of this page.
What does Daltons law state?
Dalton’s law, the statement that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual component gases. The partial pressure is the pressure that each gas would exert if it alone occupied the volume of the mixture at the same temperature.
Why does volume decrease when pressure increases?
Boyle’s law Because the volume has decreased, the particles will collide more frequently with the walls of the container. Each time they collide with the walls they exert a force on them. When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume.
What happens when the volume is doubled?
In other words, pressure is inversely proportional to volume. So, if you double the volume, it will be like halving the pressure. This also makes sense if you think about it logically. If the gas has more space to move around in, it’s going to spend less time pressing against the walls of the container.
When does the pressure of gas increase or decrease?
Boyle found that when the pressure of gas at a constant temperature is increased, the volume of the gas decreases. when the pressure of gas is decreased, the volume increases.
How is the volume of gas affected by charles’law?
Calculations using Charles’ Law involve the change in either temperature (T2) or volume (V2) from a known starting amount of each (V1and T1): Boyle’s Law -states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.
When does the volume of a gas remain the same?
This means that if a gas is heated up and the pressure does not change, the volume will. So for a fixed mass of gas at a constant pressure, volume ÷ temperature remains the same.
How is the pressure of a gas inversely proportional to its volume?
When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume. This is shown by the following equation – which is often called Boyle’s law.
