Warmup questions: (no points, but no penalty) A. If heat transfer is into the system, Q will be positive B. If heat transfer is out of the system, Q will be [negative The actual problem 380 J of work are done on a gas while its volume is decreased. At the same time, the system's thermal energy decreases by 10 J. What is the absolute value of the heat transferred into (or out of) the system in this process? Enter...

A gas inside of a test chamber has 35 J of heat removed from it as the sample is compressed by a device that does 50 J of work on it. What is the change in the thermal energy of the gas? Does the temperature of the gas increase or decrease? If the gas expands, doing 50J of work on the compressing device, does the temperature of the gas increase or decrease?

15 J of heat are removed from a gas sample while it is being compressed by a piston that does 30J of work. What is the change in the thermal energy of the gas? How does change the temperature of the gas? (increase, decrease?)

= OTHERMOCHEMISTRY Understanding the definitions of heat and work A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) From previous experiments, this chemical reaction is known to absorb 245. KJ of energy....

One mole of ideal gas is confined in a cylinder by a piston and is in the thermal contact with a heat reservoir with T=To. As a result, gas slowly expands from V1 to V2 while at the same temperature To. The internal energy of the gas does not change. Calculate work done by the gas and the heat flow into the gas.

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...
