No. The pressure can increase at constant volume or even decreasing volume. The pressure, volume, temperature and amount of gas in a container are all linked. This is expressed using the Ideal Gas Law, which says that PV = nRT. In this equation, P is the pressure, V is the volume, n is the amount of gas (in moles), R is a constant, and T is the temperature (in Kelvin). What the Ideal Gas Law says is that if the pressure goes up, something else much change, but it could be either the volume, the temperature, or the amount of gas. Let me give a few examples. Imagine some gas inside a piston. If you compress the piston, the volume will decrease, and the pressure will increase correspondingly. Now imagine a solid container (like an oxygen tank for Scuba diving for instance). If it is empty and you start filling it with gas, the pressure will increase. In this case the volume is constant, but the amount of gas is increasing ("n" in the PV = nRT equation). Same idea when you pump up your car or bike tires -- the volume changes more than with a metal container, but not much really. For more information, see the links to the left of this answer.
Yes, when temperature increases the molecules expand and push out against their surroundings, if the molecules are unbound then the matter will increase in volume. If the molecules are contained, then the increase in temperature will result in an inrease of pressure on their container (this is a gas law known as Charles's Law).
Not necessarily. According to Boyle's Law, at constant temperature, the volume of gas is inversely proportional to its pressure. This means that as pressure increases, volume decreases, and vice versa.
Using Boyle's law, P1V1=P2V2, you can see that pressure and volume must be inversely proportional to each other, so when the pressure increases, the volume must decrease. You can also answer this using common sense: if more pressure is applied to a gas, the particles will be pushed closer together, so they will take up less space, so the molar volume of the gas would decrease.

Not necessarily. That depends on the rate of increase in Temperature in conjuction with the rate of increase in volume and in conjunction with the rate of increase in quantity. However, if the rate of increase in temperature is greater than the critical rate necessary, in conjunction with the other two rates, then yes.
Assuming the gas behaves ideally, and the temperature and number of gas molecules remain constant; the pressure of a gas decreases if the volume of gas is increased.
Ideal gas law: PV=nRT.
An increase in volume must be associated with a decrease in pressure
Yes , volume will be decreased because density will be increased. We know that density =mass/volume.

What happens to the temperature if the pressure of a gas increases?
The pressure increases.
As the temperature of a fixed volume of a gas increases the pressure will?
decrease
Would the volume of a gas increase or decrease if the pressure on the gas increases?
If the pressure on a gas increases, its volume would generally decrease, provided that the temperature remains constant. This relationship is described by Boyle's Law, which states that pressure and volume are inversely proportional when temperature is held constant.
When the temperature of a gas at constant volume increases it's?
When the temperature of a gas at constant volume increases, its pressure also increases. This is because the average kinetic energy of the gas molecules increases with temperature, causing them to collide more frequently with the walls of the container, resulting in an increase in pressure.
When the pressure and the amount of gas are constant the volume increases as temperature?

How can the pressure of a gas increase?
Primarily in two ways. If the volume is decreased, the pressure will increase. Also, if the temperature increases at a constant volume, then the pressure will increase.
What happens to the temperature if the pressure of a gas increases?
The pressure increases.
As the temperature of a fixed volume of a gas increases the pressure will?
decrease
Would the volume of a gas increase or decrease if the pressure on the gas increases?
If the pressure on a gas increases, its volume would generally decrease, provided that the temperature remains constant. This relationship is described by Boyle's Law, which states that pressure and volume are inversely proportional when temperature is held constant.
Explain why increasing the temperature of a gas in closed rigid container causes the pressure in the container to increase?
Because the pressure increases The real answer is: Charles's Law. He found that if you increase the temperature of a constant pressure the volume increases also.
What happens to volume as temperature changes?
if volume of a gas increases temperature also increases
If temperature increase and volume remain constant what is pressure?
If temperature increases while volume remains constant, according to Charles's Law, pressure will increase proportionally. This is because the increased temperature will cause the gas molecules to move faster and exert more force on the walls of the container, resulting in an increase in pressure.
When the temperature of a gas at constant volume increases it's?
When the temperature of a gas at constant volume increases, its pressure also increases. This is because the average kinetic energy of the gas molecules increases with temperature, causing them to collide more frequently with the walls of the container, resulting in an increase in pressure.
When the pressure and the amount of gas are constant the volume increases as temperature?

If the volume and number of moles of gas are held constant as the temperature increase what will the pressure do?
If the volume and number of moles of gas are constant, then according to the ideal gas law, pressure is directly proportional to temperature. As temperature increases, the pressure will also increase in order to maintain equilibrium.
If a fixed sample of gas increases in temperature it must also do what?
If a fixed sample of gas increases in temperature, it will expand in volume, assuming the pressure remains constant. This is described by the ideal gas law, which states that as temperature increases, the volume of a gas also increases proportionally.
Why does vapor pressure increase with an increase in temperature?
Vapor pressure is the pressure exerted by gas molecules when they escape from a liquid. When the temperature increases, the average kinetic energy of the liquid molecules also increases, causing more molecules to have the energy to escape and become vapor. As a result, the vapor pressure increases with temperature.
