Answer:
An increase in pressure
Explanation:
The ideal gas law states that:
where
p is the gas pressure
V is the volume
n is the number of moles
R is the gas constant
T is the temperature of the gas
in the equation, n and R are constant. For a gas kept at constant volume, V is constant as well. Therefore, from the formula we see that if the temperature (T) is increase, the pressure (p) must increase as well.
Answer:
a)
b)
Explanation:
Given;
- depth of the water-tank,
- length of the pipe,
- inclination of the pipe from the horizontal,
a)
Now the effective vertical height of the water column from the free surface of the water to the bottom of the pipe at house:
Now the pressure due to effective water head:
where:
density of the liquid, here water
acceleration due to gravity
height of the liquid column
b)
Now the height of water corresponding to this pressure will be the same as the effective water head by the law of conservation of energy.
