Cathode rays are a stream of negatively charged particles or electrons in vacuum tubes. They were first seen by Johann Hittorf in 1869. They are named since they are emitted by electrode or cathode. In order to release the electrons, the electrons should first be detached from the atoms of the cathode.

The pressure caused by a sample of gas is 2.25 atm. 1 atm is
nexus9112 [7]

Answer:

0.326\frac{N}{cm^2}

Explanation:

Hello.

In this case, considering that 1 atm equals 1.01 kPa, we can compute the pressure in kPa first as shown below:

2.25atm*\frac{1.01kPa}{1atm} =3.26kPa

Now, we convert kPa to Pa, considering 1 kPa equals 1000 Pa:

3.26kPa*\frac{1000Pa}{1kPa}=3260Pa

Now, since Pa is equal to N/m², and 1 m equals 100 cm, the pressure in newton per square centimeter turns out:

3260\frac{N}{m^2}*(\frac{1m}{100cm})^2  \\\\0.326\frac{N}{cm^2}

Best regards.
