Test- particle model and matter Flashcards
1
Q
Pressure in a liquid
A
The pressure in a liquid increases with increasing depth due to the weight of the fluid above
2
Q
Density in a liquid
A
The greater the density in the liquid the greater the pressure in the liquid
3
Q
Atmospheric Pressure
A
The Earth’s atmosphere exerts pressure due to the weight of air above us.
Atmospheric pressure decreases with altitude because there is less air above.
4
Q
Upthrust and Floating
A
Objects in a fluid experience an upward force called upthrust.
An object floats if its weight is equal to the upthrust acting on it.
