As pressure increase what does volume do?
since PV=nRT and we assume that the number of moles and temperature remains constant, we can assume that PV=R as R the gas constant will not change, if pressure is increased, then volume must decrease to counteract the change in pressure
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
Why if a gas is present at 27 Celsius its volume becomes doubled when temperature increases to 327 Celsius under constant pressure?
pV = nRT we can firstly assume that n (number of moles) and R (gas constant) do not change and as pressure is also kept constant, the temperature must be proportional to the volume. Thus if temperature is increased from 27C (300K) to 327C (600K) and is doubled, the volume must also double.
What happens when pressure falls and temperature rises?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.
Why does the volume increase when the temperature increases?
Directly proportionalWell the reason is:as you usually know, when you increase volume, pressure should decrease.but in a case of constant pressure, as volume increases, well, pressure stays the same.So how does that work? The only reason pressure wouldn't change is if the temperature will increase, allowing molecules of gas to move more rapidly, and therefore creating pressure that stays constant, as the volume increases. (but if you would keep increasing temperature under constant volume, pressure would actually increase).

What usually happens in general for a gas at a constant volume?
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.

"Constant pressure" means the pressure must not change.
Metamorphic change is caused by increase of?
Increased pressure and or temperature.
Suppose the temperature of the air in a balloon is increased if the pressure remains constant.. what quantity must change Would it be Volume or Number of molecules or Compressibility OR Adhesion?
Volume
When scientists record the volume on a gas why do they also record the temperature and the pressure?
because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.
How is isothermal possible in a balloon?
Isothermal is where pressure and/or volume changes, but temperature remains constant. Pressure, Volume, and Temperature are related as: PV = nRT =NkT for an ideal gas. Here, we see that since a balloon's volume is allowed to change, its pressure remains relatively constant. Whenever there is a pressure change, it'll be offset by an equivalent change in volume, thus temperature is constant.
Does the frequency of a wave remain constant if the medium temperature and pressure do not change?
no
A change in can bring about a change in air pressure?
if the dna sequence of a gene was tacttaccgagctagact then what kind of mutation has occured This has nothing to do with the question of air pressure. Either a change of temperature or a change of volume can affect air pressure, according to Boyle's Law of Gases. Increasing temperature=increased air pressure Decreased volume=increased air pressure The reverse is also true. Decreased temperature=decreased air pressure Increased volume=decreased air pressure
How deos this change in volume affect the density of solids liquids and gasses?
A change in volume with a constant, unchanging Pressure and Temperature results in increased or decreased density, inversely dependent on increase or decrease in volume.
Pressure and volume change at a constant temperature who's law is this?
Boyles Law
What happens to the speed of a wave of the medium temperature and pressure do not change?
remains constant
