What else can I help you with?
Can you produce a lower pressure by decreasing the area a force acts on?
Yes, the pressure is inversely proportional to the area over which a force is applied. Decreasing the area that a force acts on will result in a lower pressure. This relationship is defined by the equation Pressure = Force / Area.
What is meant by a stress on a reaction at equilibrium?
A stress on a reaction at equilibrium refers to any change that disturbs the balance between reactants and products. This can include changes in temperature, pressure, or concentration. When a stress is applied, the reaction will shift in a direction that helps to relieve the stress and re-establish equilibrium.
As you get closer to the Earth the air pressure decreases or increases?
in order to make things clear, I would like to explain how is the pressure measured and what does it mean... pressure is the force (weight) exerted by an object on a specific area. and by this we can define the atmospheric pressure as the weight of the column of air ,that extends from earth to the exosphere; the upper limit of our atmosphere, divided by the area. now by increasing the length of that column (and consequently increase the weight) we increase the pressure,and the same thing can be applied when decreasing the length.
Why is the inner core of the earth solid even though its so hot?
The melting point of materials varies depending on the applied pressure. As pressure increases so does the melting temperature. This relationship is normally shown in a phase diagram.The main constituent of the inner core is iron and the inner core pressure is approximately 330-360 GPA while the temperature varies from approximately 5000 to 7000 K.The extremely high pressures in the Earth's inner core therefore drive the melting point of the iron up beyond the temperature that occurs and the metals of the inner core cannot melt.As such the inner core is solid, even though it is the highest temperature region in the Earth.Please see the related links.
Why do some rocks bend while other rocks break?
This depends on the confining pressure, the temperature and the strain rate applied to the rock mass. In general, the lower the rate of strain, the more likely ductile or plastic deformation leading to bending or folding will occur. The higher the strain rate, the more likely brittle deformation is to occur, leading to the rock "breaking". As the confining pressure increases, a materials shear strength will increase (this usually coincides with a greater depth of burial) and due to the Earth's thermal gradient an increase in temperature. As the shear strength of the rock increases, the occurrence of brittle failure is less likely while the higher temperature means that plastic deformations are more likely to occur.
What will happen if a gas is held at constant temperature has an increase in pressure applied to it?
The volume of the gas will decrease. the gas will also attempt to increase in temperature.
What will happen if a gas is held at a constant temperature has a increase in pressure applied to it?
The volume of the gas will decrease. the gas will also attempt to increase in temperature.
What will increase the volume of gas?
change the pressure and/or the temperature of the gas
What would happen if a gas was held at constant temperature has an increased temperature applied to it?
It's Pressure would rise.
When you exert force on a fluid in a closed container does the pressure increase decrease or remain constant?
When force is exerted on a fluid in a closed container, the pressure will increase. This is because pressure is directly proportional to the force applied to a fluid.
What do you do to increase the amount of pressure by whwere the force is applied?
Since Pressure is Force per Unit Area (P = F/A), there are intuitively two ways to increase pressure. You can either keep the area constant and increase the force being applied, or keep the force constant and decrease the area on which the force acts.
How automobile engine applied to Boyle's law?
As volume changes so does pressure. During the compression cycle of an engine, the volume is decreasing causing the pressure to increase. This happens so rapidly that I do not believe that temperature stays constant. For this to actually be following Boyle's law the temp is supposed to remain constant.
Will the resistance of a copper conductor decrease with an increase in the applied voltage?
If all environmental conditions remain constant then the resistance will not change appreciably with applied voltage, but the current will increase. An increase in current will raise the temperature of the conductor which will increase the resistance somewhat.
When can avogadros principle be applied?
Avogadro's principle can be applied to ideal gases at constant temperature and pressure. It states that equal volumes of gases at the same temperature and pressure contain the same number of molecules, allowing for calculations involving quantities of gases.
How do the Boyle's law is applied in a pressure cooker?
Boyle's law states that the pressure of a gas is inversely proportional to its volume at constant temperature. In a pressure cooker, as the volume decreases due to the sealed environment, the pressure inside increases, allowing the temperature to rise above the boiling point of water and cook food faster.
What will happened if a gas held at a constant temperature has an increase in pressure applied to it?
boyle's law holds good in this case and the gas experiences decrease in volume....provided the gas is not in a container with fixed dimensions! its volume will decrease
Increase this to increase the pressure?
1. Temperature of a gas 2. Force applied to a surface 3. Containing (included in closed system) mass
