I don’t understand the question
Yes. If the temperature increases, the gas expands (assuming the pressure remains constant).
You have not given enough information to answer this question. pressure depends on volume temperature and the amount of gas. just stating that the amount of gas remains constant is not enough information.
If the gas is contained at a constant volume, the pressure increases. If the gas is not contained, the pressure remains the same or drops.
It will increase? No it will decrease when the same amount of gas is held at constant temperature.
remains constant
remains constant
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.
This is the Boyle law (or Boyle-Mariotte law).
A sample of gas occupies 1.55L at STP. What will the volume be if the pressure is increased to 50 atm while the temperature remains constant?
59.04
The volume will increase in proportion to the increase in absolute temperature.
The volume will increase in proportion to the increase in absolute temperature.
