If pressure is constant how does a change in temperature affect the volume of a gas?
Pressure will rise as it is heated and lower as it is cooled according to Gay-Lussac's law.
See link below for more information. The pressure will go up. An easy way to remember this is PTV. P for pressure, T for temperature, and V for volume. Write this on a piece of paper. Put you finger on whichever one is staying the same, and push up or down on the one that is changing, and the one you leave along will show you the change.

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.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
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.
Is it true that a change in pressure may affect the equilibrium position but has no effect on the equilibrium constant?
Yes, a change in pressure may affect the equilibrium position by shifting the reaction towards the side with more moles of gas to relieve the pressure change, but it has no effect on the equilibrium constant because the equilibrium constant is determined solely by the reaction's intrinsic properties.
What happens to the pressure of gas when the volume is doubled and no change in Kelvin temperature?
According to Boyle's Law, when the volume of a gas is doubled with no change in Kelvin temperature, the pressure of the gas will be halved. This is because pressure and volume are inversely proportional in a gas at constant temperature.
Does the frequency of a wave remain constant if the medium temperature and pressure do not change?
Yes, the frequency of a wave remains constant as long as the medium temperature and pressure do not change. Temperature and pressure affect the speed of sound in a medium, not the frequency of the wave.
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
How does a change in pressure affect the ratio of PV to nRT?
A change in pressure does not affect the ratio of PV to nRT. The ideal gas law equation (PV = nRT) represents a constant relationship between pressure (P), volume (V), number of moles (n), gas constant (R), and temperature (T). Any change in pressure will lead to a corresponding change in volume, temperature, or number of moles to maintain the relationship defined by the ideal gas law.
What is the formula for calculating the change in pressure when the volume and temperature of a gas are held constant?
The formula for calculating the change in pressure when the volume and temperature of a gas are held constant is: P (nRT/V)T, where P is the change in pressure, n is the number of moles of gas, R is the gas constant, T is the temperature, V is the volume, and T is the change in temperature.

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.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
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

How does volume of matter change with increase in temperature?
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.
