<h2>
Answer: The volume will triple (increase by a factor of three).</h2>
Explanation:
The expression for an Ideal Gas is:
(1)
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas
Finding :
(2)
If we are told the the amount of gas and pressure remain constant, but we increase the temperature by a factor of three; we will have to rewrite (2) with the new temperature :
(3)
(4)
Now, if we compare (2) with (4), it is clearly noticeable the volume of the gas has increased by a factor of 3.
Answer:
What soil conditions favor the use of belled caissons?
Answer:
- where the bell can be unearthed from a solid surface.
- where the supporting stratum below the bottom of the caisson is impermeable to water movement.
What soil conditions favor piles over caissons?
Answer:
- non-cosheal soils
- subterranean water or excessive depth of bearing strata make caisson unworkable
What type of piles are especially well suited to repair or improvement of existing foundations ?
Answer:
Without hammering, minipiles or helical piles are placed which escapes much of the vibration and noise associated with traditional pile installation. for working close to existing buildings or for improving the exiting foundations where excessive vibration could damage exiting structures or noise may interfere with ongoing activities these piles are good options.
Why?
Their slenderness involves little or no displacement of the soil, thus minimizing the risk of disturbance to nearby foundations.
List and explain some cost thresholds frequently encountered in foundation design.
Answer:
building below the water table- site dewatering must occur, strengthening of slopes supper system must be done and waterproofing of the foundation all of which entails money
building near existing building - this requires underpinning(The process of reinforcing the base of an existing building or other structure underpins it.)
increase in column/wall load- building height determines the foundation depth
A period of a satellite is the time taken by the satellite to travel round a
body.
The comparison between the periods , and is
Reason:
The period, <em>T</em>, of a satellite is given as follows;
Volume of the planet <em>A</em> =
Mass of planet <em>A, </em> =
Volume of the planet <em>B</em> =
Mass of planet <em>B, </em> =
Period of the satellite on planet <em>A</em>, , is given as follows;
Period of the satellite on planet <em>B</em>, , is given as follows;
Therefore, get;
Therefore, = (2·√2)·
The comparison between and is therefore;
