Answer:</h3>
1270 Psi
<h3>
Explanation:</h3>
<u>We are given;</u>
- Pressure in the tank, P₁ as 422 psi
- Temperature in the tank, T₁ as 20.0 K
- New temperature in the tank, T₂ as 60.0 K
We are required to determine the pressure at 60.0 K
- We are going to use the pressure law;
- According to the pressure law, the pressure of a gas is directly proportional to the temperature at constant volume.
- That is;
![P\alpha T](https://tex.z-dn.net/?f=P%5Calpha%20T)
- Thus,
![\frac{P}{T}=constant](https://tex.z-dn.net/?f=%5Cfrac%7BP%7D%7BT%7D%3Dconstant)
- At different pressures and temperature;
![\frac{P1}{T1} =\frac{P2}{T2}](https://tex.z-dn.net/?f=%5Cfrac%7BP1%7D%7BT1%7D%20%3D%5Cfrac%7BP2%7D%7BT2%7D)
- Thus, rearranging the formula;
![P2=\frac{P1T2}{T1}](https://tex.z-dn.net/?f=P2%3D%5Cfrac%7BP1T2%7D%7BT1%7D)
Hence;
![P1=\frac{(422Psi)(60K)}{20}](https://tex.z-dn.net/?f=P1%3D%5Cfrac%7B%28422Psi%29%2860K%29%7D%7B20%7D)
![P1=1266Psi](https://tex.z-dn.net/?f=P1%3D1266Psi)
Therefore;
P₂=1266 Psi
= 1270 Psi
Thus, the pressure at 60.0 K is 1270 Psi
