Physics Grade 10 Gas laws Ideal gas law Solving problems

1. When the pressure of an ideal gas of a given mass at a temperature of  Т=273 K is P₁=10 kPa its volume V₁=20 m³.

Construct a graph of the isothermal process of this gas if the final gas pressure  P₂=4 kPa.

a on coordinate axes p-V.

b on coordinate axes V-T.

c on coordinate axes p-T.

2. In its initial state, a gas occupies a volume V₁=1 m³ at a temperature of Т₁=200 K. The final temperature of the gas is Т₂=300 К.

Construct a graph of the isobaric process of the ideal gas at a pressure of P=1·10⁵ Pa:

a on coordinate axes p-V.

b on coordinate axes V-T.

c on coordinate axes p-T.

3. The figure below shows a closed cyclic process on the coordinate axes V-T for a constant mass of an ideal gas.

a Name each section of this cycle, and for each section identify the process that is occurring: compression, expansion, heating, or cooling.

b Draw this cycle on coordinate axes p-V.

с Draw this cycle on coordinate axes p-T.
