1. The pressure falls more rapidly in a quasi-static, adiabatic process than along an isotherm when the volume of a gas is increased.
2. If a thermometer measures the temperature of two objects as being equal, you can conclude that if the objects are placed in thermal contact, no heat will flow between them.
3. All reversible engines operating between the same two temperatures have the same efficiency.

My answers were F,T,T, Would appreciate other opinions and feedback.

I got true for questions 2 and 3 as well. But for 1 I got true. If I remember correctly, for an adiabatic process where the gas expands the internal energy and thus the temperature both drop. So in the final state the adiabatic process lies on a lower isotherm curve than the isotherm curve it originally lied on in the initial state. And so I got true for the pressure dropping more quickly for adiabatic than isotherm.
