In the context of Boyle’s Law, which describes the relationship between the pressure and volume of a gas at constant temperature, the terms ‘Torr’ and ‘Atm’ refer to units of pressure.
The Torr is a unit of pressure defined as 1/760 of an atmosphere (atm). In practical terms, 1 Torr is approximately equal to 133.322 Pa (Pascals). This unit is often used in vacuum measurements and is named after Evangelista Torricelli, the Italian physicist and mathematician who first studied the pressure of gases.
The Atm, or atmosphere, is another unit of pressure traditionally defined as being precisely equal to the average atmospheric pressure at sea level. It is equivalent to 101,325 Pa. Boyle’s Law is frequently utilized in contexts dealing with gases in varying pressures, making the understanding of these units crucial. When working with Boyle’s Law, knowing how to convert between Torres and Atmospheres can help you accurately calculate the properties of gas under changing conditions.
