Is a liquid at normal temperatures and pressures a physical or chemical change?
This liquid is only a liquid, not a change.
What are normal R22 operating pressures?
The pressures depend on the temperatures so it is not possible to give "normal" temperatures. The pressures change with the outdoor and indoor temperatures. You need to be EPA certified to attach gauges to the unit to check the pressures.
What gas do oxygen have?
Oxygen IS a gas at normal temperatures and pressures
What is the normal phase of Ta?
Tantalum (sometimes called Columbium in the US) is solid at normal temperatures and pressures.
Solid at normal temperatures and pressures a physical or chemical property?
Physical
What is normal population?
Quinta Normal's population is 104,012.
What is Quinta Normal's population?
Quinta Normal's population is 104,012.
Are there any elements that can not freeze?
Hydrogen and helium cannot be solidified at normal pressures, however they will 'freeze' at temperatures near absolute zero under high pressures.
What is selective breeding cause by?
Selective breeding is caused by humans, we created selective breeding by finding out that if we mate two lions one with white lion gene (and white fur) and one with out the gene (with normal fur )there is a good chance that a white lion may be born but also a good chance a normal lion may be born
What cause blood pressure?
The force of the heart pushing and pulling blood through the arteries and veins causes a change in the force felt in those areas. This regular change from normal is blood pressure.Changes from the "normal" pressures can be caused by many things, including alcohol, stress, other health issues and old age.BASICALLY: The force with which the ventricals contract
What is the normal pressure high and low for a roof top unit?
The refrigerant pressures are dependent on the type of refrigerant.
How would the partial pressures of O2 and CO2 change in an exercising muscle?
Although venous levels change, arterial Pco2 and Po2 levels remain surprisingly constant during exercise. In fact, Pco2 may even decline to below normal and Po2 may rise slightly because of the efficiency of the respiratory adjustments. Increased blood flow does not cause a change in gas pressures. the only way to change gas pressures is by altering atmospheric pressure, ie. scuba diving, or changing elevation. Partial pressure of any blood born gas is always directly proportional to atmospheric pressure as evidenced by Dalton's law of partial pressures. However in exercising muscle metabolic processes temporarily increase Pco2 and decrease Po2 until equalized by sufficiently oxygenated arterial blood. So the short answer to your question is that intramuscular Pco2 pressures would increase and Po2 would decrease, but the partial pressures in the blood would remain constant.
