The answer is in the picture which is given below:
Answer:
The new pressure will be 0.225 kPa.
Explanation:
Applying combined gas law:
where,
are initial pressure and volume at initial temperature 
.
are final pressure and volume at initial temperature 
.
We are given:
Putting values in above equation, we get:
Hence, the new pressure will be 0.225 kPa.
<h2>Answer:</h2><h3>The temperature of the gas: V</h3>
The temperature of gas is a variable quantity. It can be changed by changing energy or pressure of gas.
<h3>The amount of gas in the tube (in terms of mass and moles): C</h3>
It is a constant entity. As mass of gas once taken can not be changed by changing temperature, pressure etc.
<h3>The radius of the tube: C</h3>
The radius of tube cannot change at any rate.
<h3>The temperature of the gas (changed by the water surrounding it): V</h3>
It can be changed by changing the temperature of water surrounding it.
<h3>The type of gas: C</h3>
It can never be changed.
<h3>The pressure of the gas: V</h3>
It can be changed by simply changing temperature and volume of gas.
