<h2>Hello!</h2>
The answer is: 4.77atm
<h2>Why?</h2>Since there's a fixed volume, we can use the the Gay-Lussac's Law which stablish a relation between the pressure and the temperature:
<em>P</em> is the volume of the gas
<em>t</em> is the temperature of the gas
<em>k </em>is the proportionality constant
We also have the following equation:
Where:
We are asked to find the pressure in atm, so we must convert 483.73kPa to atm:
Then,
Have a nice day!
Converting the temperature, 295 K from Kelvin to Celsius scale:
Water has a boiling point of and a melting point of
When we compare water at two different temperatures, we can say that water is in liquid form at both these temperatures as both of them are quite below the boiling temperature and above the melting temperature.
The temperature difference between water at the given two temperatures =
Water at is at a higher temperature and so is warmer than water at a lower temperature of
