Zeroth and first laws of trermodynamics

The zeroth law of thermodynamics states that if two bodies are each in .................. equilibrium with some third body, then they are also in ....................... with each other.

The most common application of the Zeroth Law of Thermodynamics is the thermometer. Using a simple thermometer containing .................... in a tube, we may watch the Zeroth law in operation. The liquid inside the tube expands as the temperature rises because the tube's area remains constant.

The First Law of Thermodynamics states that energy cannot be ...................... or destroyed; it can only be ..................................... from one form to another.

What is an adiabatic process?

• A process with no change in temperature
  

• 
  A process with no heat exchange with the surroundings
  

• 
  A process with no change in volume
  

• 
  A process with constant pressure

In an adiabatic expansion of an ideal gas, the temperature of the gas:

• Increases
  

• 
  Decreases
  

• 
  Remains constant
