Convert 380 torr to atm:
The Correct Answer and Explanation is:
To convert 380 torr to atmospheres (atm), we use the standard conversion factor:
1 atm = 760 torr
Now apply this conversion:Pressure in atm=380 torr760 torr/atm=0.5 atm\text{Pressure in atm} = \frac{380\ \text{torr}}{760\ \text{torr/atm}} = 0.5\ \text{atm}Pressure in atm=760 torr/atm380 torr=0.5 atm
Final Answer:
380 torr = 0.5 atm
Explanation:
Pressure is a physical quantity that measures the force applied on a given area. Different units are used to measure pressure depending on the context or the system being used. Torr and atmospheres are both common units of pressure. The torr is named after the Italian physicist Evangelista Torricelli, who invented the barometer. One atmosphere is the average pressure at sea level on Earth and is equivalent to 760 torr.
To convert between torr and atmospheres, it is essential to know the exact ratio between them. One atmosphere equals 760 torr. This is a fixed, defined relationship based on historical measurements and standards. Therefore, to convert from torr to atm, you divide the given number of torr by 760.
In this case, 380 torr is exactly half of 760 torr. This means it is equal to 0.5 atm. The operation used is simple division:380760=0.5\frac{380}{760} = 0.5760380=0.5
This method can be applied to any pressure value in torr to convert it into atmospheres. Conversely, to convert from atm to torr, you would multiply the value in atm by 760.
Unit conversion like this is important in science and engineering where pressure may be reported in different units depending on the measurement tools or the region. Being able to convert units correctly ensures accurate interpretation of data and proper functioning of systems that rely on pressure measurements.
