according to Boyle's law, volume of gas shrinks with decreasing pressure
temperature affects air pressure when it is cold air pressure decreases when it gets warm air pressures rises
Variation of pressure and temperature..that changes. Gas into liquid..temp should be decreased likewise pressure..
The boiling point of a liquid should be recorded when the liquid reaches a constant temperature at which it changes from a liquid to a gas (vapor) under a specific pressure. This usually occurs when the vapor pressure of the liquid equals the atmospheric pressure.
The scientist should check for variations in temperature, the number of moles of gas present, or the nature of the gas molecules (e.g., size, shape, mass). These factors can affect the gas pressure in a sealed chamber with a fixed volume according to the ideal gas law.
I do my own blood pressure and temperature every day and if i get a reading that i think is wrong i do it again, if it is still the same i go to my doctor or phone the health services if i am worried about it, or there are sites online that will explain what your blood pressure should be, hope this helps.
At constant temperature if the volume of a gas decreses what should I do now
The pressure should be equal to a saturated suction temperature of around 40*F. The pressure would differ depending on which refrigerant is used.
Depends on temperature and relative humidity. I'd recommend you do a search for an 'R134a pressure/temperature chart'
You need to specify what kind of system. Automotive AC systems and home AC systems use different refrigerants. That, along with the temperature/pressure relationship and ambient air temperature, all factor into what your high pressure (and, consequentially, low pressure) side should read on your manifold pressure gauge.
An ideal thermometer should have a narrow, uniform tube with a bulb at one end to hold the temperature-sensitive liquid. This shape allows for easy reading of the temperature, as the liquid expands and contracts uniformly with temperature changes. The narrow tube also allows for quick response to changes in temperature.
The liquid in a thermometer should be a good conductor of heat so it can quickly and accurately reflect changes in temperature. Good conductivity ensures that the liquid expands or contracts rapidly with changes in temperature, allowing for precise temperature readings.
The gas is likely to expand and raise the pressure inside the can. Should the pressure become too great the can will burst.
