8) A fire breaks out, raising the ambient temperature by 224.0K while 82.0g of gas leak out of the tank. Calculate the new temperature and the number of moles of gas remaining in the tank. a) 514K,4.01mol b) 293K,2.34mol c) 852K,4.01mol d) 10K,782mol 9) When you suddenly stand up after lying down for a while, your body may not compensate quickly enough for the pressure changes and you might feel dizzy for a moment. If the gauge pressure of the blood at your heart is 12.13kPa and your body doesn't compensate, what would the pressure be at your head, 45.3cm above your heart? (assume blood mass density =1060kg/m3 ) a) 4.54kPa b) 7.42kPa c) 201kPa d) 15.2kPa 10) From the above question: If the gauge pressure of the blood at your heart is 12.13kPa and your body doesn't compensate, what would it be at your feet, 1.30×102cm below your heart? (assume blood mass density =1060kg/m3 ) a) 25.6kPa b) 4.53kPa c) 154kPa d) 0.23kPa 11) For 2 moles of He gas inside a cylinder at 20 degrees Celsius: Find the total internal energy of the He gas. a) 7.3kJ b) 5.1kJ c) 0.25kJ d) 120kJ
