<p>The temperature of 1 mole of an ideal monoatomic gas is increased by&nbsp;&nbsp;<span class="equation">\(50^0\)</span>C &nbsp;at constant pressure. The total heat added and change in internal energy are&nbsp;<span class="equation">\(E_1\)</span>and&nbsp;<span class="equation">\(E_2\)</span>, respectively.&nbsp; If&nbsp;<span class="equation">\(\frac{E_1}{E_2} = \frac{x}{9} \)</span>. then the value of x is_____</p>
