Question A14 Heat is added to a cylinder containing 1.005 kg of air during which the mass and the pressure are both kept constant. The temperature of the air increases from 20°C to 120°C. What will be the work done by the system during this process? (A) 0 kJ (B) 28.84 kJ (C) 72.16 kJ (D) 101.0 kJ

In a common demonstration, a bottle is heated and stoppered with a hard-boiled egg that's a little bigger than the bottle's neck. When the bottle is cooled, the pressure difference between inside and outside forces the egg into the bottle. Suppose the bottle has a volume of 0.500 L and the temperature inside it is raised to 80.0 while the pressure remains constant at 1.00 atm because the bottle is open. (a) How many moles of air are inside? (b) Now the egg is put in place, sealing the bottle. What is the gauge pressure inside after the air cools back to the ambient temperature of 25 but before the egg is forced into the bottle ?

A mole of ideal monatomic gas at 0 and 1.00 atm is warmed up to expand isobarically to triple its volume. How much heat is transferred during the process?

An ideal gas initially at 300 K undergoes an isobaric expansion at 2.50 kPa. If the volume increases from 1.00 m3 to 3.00 m3 and 12.5 kJ is transferred to the gas by heat, what are (a) the change in its internal energy and (b) its final temperature?

A thirsty nurse cools a 2.00 L bottle of a soft drink (mostlywater) by pouring it into a large aluminum mug of mass 0.257 kg andadding 0.120 kg of ice initially at -15.0°C. If the soft drink and mugare initially at 20.0°C, what is the final temperature of the system, assumingthat no heat is lost?

The internal energy of a gas system increases by 14.7 J and 6.7 J of work isdone on the system. What is the net amount of heat that must have beenadded to the system in joules?

One mole of a dilute diatomic gas occupying a volume of 10.00 L expands against a constant pressure of 2.000 atm when it is slowly heated. If the temperature of the gas rises by 10.00 K and 400.0 J of heat are added in the process, what is its final volume?

A nyperthermic male weighing 104kg, has a mean body temperature of 42°C. He iIs to be Cooled to 37°C by placing him in a water bath, which is initially at 25°C.What is the minimum amount of bath water required to achieve this result? The specific heat of the body is 3.5kJ/kg*K, and the specific heat of water is 4.19KJ/Kg*K.

One mole of an ideal gas does 4500 J of work as it expands isothermally to a final pressure of 1.00 × 105 Pa and volume of 0.031 m3 what was the initial volume ofd the gas inm cubic meters? What is the tenpature of the gas in kelvin?

A frictionless piston–cylinder device initially contains 200 L of saturated liquid refrigerant-134a. The piston is free to move, and its mass is such that it maintains a pressure of 900 kPa on the refrigerant. The refrigerant is now heated until its temperature rises to 70°C. Calculate the work done during this process.
