A quantity of ideal monatomic gas consists of n molecules initially at temperature Ta. The pressure and volume are then slowly doubled in such a manner as to trace out a straight line on a p-V diagram. (a) In terms of n, R, and Ta, calculate: The work W (i) (ii) The internal energy AU (b) What would be the value of the molar specific heat for this process?

Suppose 3.32 moles of a monatomic ideal gas expand adiabatically, and its temperature decreases from 371 to 254 K. Determine (a) the work done (including the algebraic sign) by the gas, and (b) the change in its internal energy.

A balloon holding 4.50 moles of oxygen (0,) gas absorbs 935 J of thermal energy while doing 112 J of work expanding to a larger volume. HINT (a) Apply the first law of thermodynamics. (b) Recall that the molar specific heat at constant volume, C, takes different values depending on whether the gas is monatomic or diatomic. Click the hint button again to remove this hint. (a) Find the change in the balloon's internal energy (in J). (b) Calculate the change in temperature of the gas (in K). K

A monatomic ideal gas expands adiabatically from 1.8 m³ to 4 m³. If the initial pressure is 102 kPa, calculate the energy in kJ transferred to or from the system by heat.

Suppose 6.36 moles of a monatomic ideal gas expand adiabatically, and its temperature decreases from 387 to 263 K. Determine (a) the work done (including the algebraic sign) by the gas, and (b) the change in its internal energy.
