Question

The burning of fossil fuels creates a low pressure region. Pick out the correct options regarding this.

• A. As temperature increases, pressure decreases
• B. As temperature increases, pressure increases
• C. As temperature increases, molecules start moving and air expands
• D. As temperature increases, molecules comes closer to each other

Answer 1

Answer: (A), (C)

As temperature increases, molecules start moving and air expands

When the fossil fuels are burnt, temperature increases. This increase in temperature, increases the kinetic energy of air molecules and they start moving. Thus the same number of molecules will occupy more space. This reduces the pressure in that region. Therefore, the burning of fossil fuels creates a low pressure region.
