Why does atmospheric pressure decrease with altitude? A6. There are fewer air molecules above you as altitude increases, so the weight of the air column decreases.
Calculate the pressure at the bottom of a 5 m deep swimming pool. (Density of water = 1000 kg/m³, ( g = 10 ) N/kg) A4. ( P = h \rho g = 5 \times 1000 \times 10 = 50,000 ) Pa (or 50 kPa) aqa science p2 5.5 activity sheet answers
Here are the for a typical AQA GCSE Science P2 – 5.5 Activity Sheet (topic: Pressure and Pressure Differences – often part of the Particle Model of Matter or Forces unit, depending on the specific sheet). Why does atmospheric pressure decrease with altitude
Why does a dam have a thicker base than top? A3. Pressure increases with depth, so the base must be thicker to withstand the greater force. Calculate the pressure at the bottom of a
