1. Calculate the change in the internal energy of the following systems and then determine whether the processes are endothermic or exothermic: (a) 45 kJ of heat is transferred from the system to the surroundings. Answer: AE- the process is (b) 605 J of work is performed by the surroundings to the system. Answer: AE (c) When 145 J of work is done by the surroundings to the system, 212 J of heat is transferred from the system to the...

1.) A system absorbs 1.56E+2 kJ of heat and the surroundings do 1.107E+2 kJ of work on the system. What is the change in internal energy (in kJ) (ΔU) of the system? 2.) A sample of gas in a cylinder is provided with 6.221E+2 kJ of heat. This causes a piston to then compresses the gas by doing 4.343E+2 kJ of work to the gas. What is the change in internal energy of the gas during this compression? 3.)A gas...

A ball is thrown straight up such that it leaves your hand with 200 Joules of kinetic energy. Suppose we choose the ball + Earth as our system and we use the height of the ball when it leaves your hand as h = 0. Answer the questions below ignoring air resistance. Initial gravitational potential energy when the ball leaves your hand = Kinetic energy when the ball is half way to its maximum height = j. Gravitational potential energy...
1) Calculate the heat through a glass window that is 30.0 cm*150 cm in area and 1.20 mm&n
1) Calculate the heat through a glass window that is 30.0 cm*150 cm in area and 1.20 mm thick. Assume the temperature onthe inside of the window is 25.0�C while the outside temperature is 8.00�C. 2)Five hundred joules of heat is absorbed by a system that does 200 J of work on its surroundings. What is the change in the internal energy of the system? 3)An ideal gas expands isothermally, performing 8.80 kJ of work in the process. Calculate the heat absorbed during the expansion. 4)A gas contained in a cylinder that has a piston is kept at a constant pressure of 2.80*10^5Pa. The gas expands from0.500 m^3to 1.50 m^3 when 300 kJ...

He gas is confined to a piston and cylinder with a mechanical stop that prevents the cylinder from expanding. The temperature of the gas is 298 K, the volume of gas in the cylinder is 1.20 L and its pressure is 2.15 bar. The ideal gas EOS is very accurate for He under these conditions. Starting from the final state of the He gas in part (b), the gas (and apparatus) was cooled from 298 K to 263 K. The...
