A. Find the boiling temperature of a juice that is boiling at an absolute pressure of 31.19 KPa. Assume that the boiling point elevation is negligible.
B. Find the enthalpy of superheated steam with pressure 150 kPa and temperature 150°C.
C. If the enthalpy of saturated steam at 50°C and 55°C is 2592.1 kJ/kg and 2600.9 kJ/kg, respectively, find the enthalpy at 53°C.
Three resistors with values of 4.0 \Omega,7.0 \Omega, and13 \Omega areconnected in series in a circuit with a 6.5 Vbattery. What is the total equivalent resistance? What is the current in each resistor?
Is it possible for both the pressure and volume of a monatomic ideal gas to change without causing the internal energy of the gas to change?
To determine the specific heat of an object, a student heats it to 100 in boiling water. She then places the 68.5 object in a 196 aluminum calorimeter containing 135 of water. what is the specific heat of the object
A sled weighing 61.0 N is pulled horizontally across snow so that the coefficient of kinetic friction between sled and snow is 0.100. A penguin weighing 67.0 N rides on the sled, as in the figure below. If the coefficient of static friction between p..
