Clouds release moisture on what side of the mountain?
The windward side of a mountain tends to have winds ascending it which leads to expansion in the air, a drop in temperature, cooling ,rise in relative humidity and condensation. The water vapor gets carried by the wind and leads to cloud formation and rainfall.
How does a sustained high temperature affect ceramics?
Brittle materials, especially ceramics, are prone to fracture by sudden changes in temperature. A sudden change can cause rapid and unequal expansion or contraction that set up tensile stresses in the material causing it to break. For example, putting a drinking glass or glass bottle in boiling water will often result in it breaking.
Can water be used faster than precipitation?
Yes and it causes the water table to fall.
What causes most water pollution?
Industrial Waste
What is a tidal wave caused by a earthquake?
This is known as a tsunami.
What are the causes of expansion and contraction of water in soil formation?
Expansion of water in soil formation can be caused by freezing and thawing cycles, leading to frost wedging. Contraction of water can occur when water evaporates from the soil, resulting in shrinkage. Both expansion and contraction play important roles in shaping soil structure and contributing to the weathering of rocks.
What causes creaking in hot water pipes?
Expansion and contraction
Is an Expansion and contraction with regard to weathering are caused by rusting?
Expansion and contraction in weathering are caused by temperature changes, not rusting. Rusting is a chemical process that occurs when iron reacts with oxygen in the presence of water, leading to the formation of iron oxide (rust). However, rusting can contribute to the weakening and eventual breakdown of materials, which may then be more susceptible to expansion and contraction due to temperature changes.
Describe how temperature changes can make cracks form in rocks?
Temperature changes cause rocks to expand and contract, leading to stress within the rock. Over time, repeated expansion and contraction can weaken the rock and lead to the formation of cracks. Additionally, differential rates of expansion and contraction in different parts of the rock can cause internal forces that contribute to crack formation.
Is the boiler expansion tank full of water?
The boiler expansion tank should not be full of water. It should have a mix of water and air to allow for expansion and contraction of the water in the system. If the tank is full of water, it may indicate a problem with the tank or the system.
Why the process of boiling water is noisey?
At the minute site of the formation of a bubble of boiling, we have some water turning instantaneously to steam. This has a much larger volume than water, and expands VERY rapidly. In this expansion, it forces some water away to make space for the bubble, and it is these forces of expansion, and the reaction to them, that causes the noise.
Could expansion or contraction cause problems?
Yes, expansion or contraction of materials can cause problems in structures, particularly if they are not accommodated for in the design. If expansion or contraction occurs unevenly or is not properly controlled, it can lead to issues such as warping, cracking, or failure of the structure. Proper planning and use of materials that can accommodate thermal expansion and contraction is important to avoid these problems.
What causes pressure in a radiator?
Expansion of the water inside due to heat causes the system to be pressurised.
Freeze-thaw is an example of?
Freeze-thaw refers to the process of water freezing and then thawing, which can cause physical weathering of rocks and damage to infrastructure due to the expansion and contraction of water. It is a common phenomenon in regions with fluctuating temperatures, leading to the formation of ice wedging and frost heaving.
Expansion and contraction with regard to weathering are caused by rusting.?
Expansion and contraction in materials due to rusting occur when iron in the material reacts with oxygen in the presence of water, forming iron oxide (rust) which has a larger volume than iron. This expansion and contraction can lead to cracking and weakening of the material over time.
At what temperature do the combined effects of contraction and expansion produce the smallest volume of water?
Water has its smallest volume (for any given mass) at 4 degrees Celsius.
Does gold expand under hot or cold water?
Heat causes expansion.
