Assuming ideal gas law, and closed system (constant volume) P1/T1=P2/T2, ensuring that the Temperature is in Kelvin so the new P is =854.5 kpa
235/110 x 400 = 854.5454 kPa if no change in volume
A : 845.46 kPa
the answer is D 854.46 kPa
854.46 kPa
A statement, derived by French physicist and chemist Joseph Gay-Lussac (1778-1850), which holds that the pressure of a gas is directly related to its absolute temperature. Hence, the ratio of pressure to absolute temperature is a constant.
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.
decreases
Using the Celsius temperature scale, it is not correct. But doubling the temperature using the Kelvin temperature scale, where zero is the absolute minimum gegree possible, will double pressure . p1/T1=p2/T2=constant.
Boyle's law states that the volume of a gas is inversely proportional to its pressure if the temperature remains constant.
Usually we use a temperature of 20 °C and an absolute pressure of 101.325 kPa for 1 atmosphere.
A : 845.46 kPa
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)
i need to explain what an absolute pressure gauge measures
Other things being equal, the pressure falls in the same proportion as the absolute temperature.
Absolute Zero
Usually we use a temperature of 20°C and an absolute pressure of 101.325 kPa for 1 atmospher.
absolute pressure
A pressure measurement, in comparison to atmospheric pressure on Earth, at sea level, near sea level, at standard temperature, usually expressing an absolute pressure (but does not have to be). 1 atmosphere absolute = 1.01325 bar absolute 1 atmosphere absolute = 101,325 pascal absolute 1 atmosphere absolute = 14.69595 psi absolute

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.
