What are the differences between adiabatic, isothermal, and isobaric processes in thermodynamics?
In thermodynamics, adiabatic processes do not involve heat exchange, isothermal processes occur at constant temperature, and isobaric processes happen at constant pressure.
What happen to the mercury in a thermometer when the temperature increase?
When the temperature increases, the mercury in a thermometer expands and rises up the column because the volume of the liquid increases with temperature. This expansion is linear and is used to indicate the rise in temperature on the thermometer scale.
Why gaps are left in concrete slaps?
Gaps in concrete slabs, also known as control joints, are intentionally placed to control cracking caused by shrinkage as the concrete cures. These joints help to direct where cracks may occur, allowing them to happen in a controlled manner along the joint lines rather than randomly across the slab. Without control joints, cracks may still form but they would be more unsightly and difficult to predict.
What will happen if the ignition temperature is lower than the room temperature?
If the ignition temperature is lower than the room temperature, the substance will not ignite or burn spontaneously at room temperature. Ignition temperature refers to the minimum temperature required for a substance to ignite and sustain combustion, so if it is lower than the room temperature, the substance will remain stable at that temperature.
What is the temperature when a tornado happens?
The temperature during a tornado can vary, but it is typically around the same as the surrounding air temperature. Tornadoes can occur in a wide range of temperatures, as they are caused by specific atmospheric conditions rather than just temperature alone.
When temperature rises what will happen to the gaps between the concrete sections?
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
When the temperature rises what will happen to the gaps between the concrete sections?
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
When earthquake happen when these sections of earth crust move?
earthquakes happen when these sections of earths crust move
Why are there gaps at regular spots in the side walk?
They're called "expansion joints". Concrete expands and contracts with temperature changes. The expansion joints allow this to happen without cracking the concrete slab.
How does concrete behave in fire?
Concrete will react differently according to the temperature experienced. for normal strength concrete nothing will happen at less than 500c but after that it starts losing its strength and cracks will appear will fail from 5-6 hours and it may explode but exploding is less likely to happen but for high strength concrete at a very high 500c-700c it well explode suddenly
What earthquakes happen when these sections of earth's crust move?
a salami.
Why does grout loss happen in concrete?
Cement seggregates
What is the difference between the setting and hardening of concrete?
Setting indicate the beginning of stiffening of concrete ,in this case the concrete has not any strength and any cracks if occur can be re unit the concrete in this state just like a dough bread afar setting the concrete stiff and become hard and get strength and any cracks if happen cant be re unit
Will happen to the strength of the concrete if impurities such as clay and silt occur in the sand?
The impurities like clay and silt in sand can reduce the strength of concrete by weakening the bond between the cement and aggregates. This can lead to an increase in voids in the concrete mixture, reducing its structural integrity and overall durability. It is important to use clean and well-graded sand to maintain the desired strength of the concrete.
What will happen if you bang your head on concrete?
You may hurt yourself badly.
What will be happen when the air content was not in the concrete mix?
A better, more homogenous, cast.
WHAT HAPPEN TO THE TEMPERATURE AS YOU GO DEEPER INTO THE OCEAN?
Temperature decreases with depth.
