Gauge pressure = absolute pressure - atmospheric pressure.
Atmospheric pressure (at sea level) is generally taken to be 101.325kPa.
so the answer is (C) = 448.955 kPa
The gauge pressure would be 448.955 kPa.
448.995 kPa
The absolute pressure is approximately 256 kPa.
Boyle's Law says that PV is constant for ideal gas at a constant temperature. The pressure used should be the absolute pressure, not the gage pressure. Ge the absolute pressure should be obtained using : P = PG + PE where PG = gage pressure ( kPag , psig, etc. ) PE = barometric pressure ( kPaa, psia, etc. ) P = absolute pressure ( kPaa , psia, etc. ) ( PG + PE ) ( V ) = Constant for constant temperature The g in kPag and in psig indicates gage pressure.
Boyle's law.
Yes. Any sample of gas in a closed container will exert pressure on the container, as long as the temperature of the gas is above absolute zero. You can force the gas into a smaller volume by shrinking the container, but that action raises the temperature and pressure of the gas.
The absolute temperature of the oven is 745/345 times the absolute temperatureof the ice bath.(745/345) x (273.15 K) = 589.85 K = 316.7° C.
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
The gauge pressure would be 448.955kPa.
if the gauge pressure is 206 kPa, absolute pressure is 307 kPa
The absolute pressure is approximately 256 kPa.
If a gas has a gage pressure of 156 kPa its absolute pressure is approximately?

Lots of things are true... Here are some:* For constant pressure, the volume of an ideal gas is directly proportional to the absolute temperature. * For constant volume, the pressure of an ideal gas is directly proportional to the absolute temperature.

I suppose you mean the formula for the variation in pressure. The simplest expression of this is, at a fixed temperature,and for a given mass of gas, pressure x volume = constant. This is known as Boyle's Law. If the temperature is changing, then we get two relations: 1. If the pressure is fixed, volume = constant x temperature (absolute) 2. If the volume is fixed, pressure = constant x temperature (absolute) These can be combined into the ideal gas equation Pressure x Volume = constant x Temperature (absolute), or PV = RT where R = the molar gas constant. (Absolute temperature means degrees kelvin, where zero is -273 celsius)
Charles's law states that at constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its absolute temperature. For fixed mass of an Ideal Gas at constant pressure the volume it occupies is directly proportional to its absolute temperature. So, if you double the absolute temperature of a gas while holding its pressure constant, the volume has to double. There is no such thing as an Ideal Gas. So, doubling the temperature of a real gas will not exactly double its volume. However, the general principle hold true. If you increase the temperature of any gas at constant pressure the volume it occupies will increase.
