The pressure of gas always increases with increasing temperature?

True.
The Ideal Gas Law is PV = nRT, where P is pressure, V is volume, n is the amount of gas, R is the gas constant, and T is temperature. You can see clearly that, all other things being equal, pressure is directly proportional to temperature.

What effect does raising the temperature have on the speed of reaction for the forward reaction and why?
In general, but not always, increasing the temperature will increase the rate of the forward reaction. This is because an increase in temperature increases the speed at which the molecules move, increasing the kinetic energy, and thus making it easier to reach the activation energy. Of course, this is true only for endothermic reactions. If the reaction is exothermic, then increasing the temperature will slow down the forward reaction.
Is the volume of a gas directly proportional to the pressure?
The temperature
What would increase the reaction rate?
raising the temperature of the reactants, by increasing their surface area, by increasing the concentration of reactants, by stirring the reactants, or by adding a catalytic agent can increase reaction rates
Under which conditions will the volume of a given sample of a gas always decrease?
The Ideal Gas Law states that PV=nRT, where P=pressure, V=volume, n=number of moles of gas, R=the relativity constant, and T=temp in Kelvin. According to this law, volume (V) varies as V=(nRT)/P. Using this, we can determine that the volume would normally increase with an increase in the number of moles and/or an increase in the temperature and/or a decrease in pressure. Therefore, we can logically determine that the volume of a gas would decrease in the instance of increasing temperature if either the number of moles of gas was decreased or the pressure was increased (to an extent where the level of volume increase by temperature change has been overcome.)
What is atmospherical pressure at higher and lower altitude?
In general, barometric pressure, or atmospheric pressure, drops as you go up in elevation. For example, at 18,000 ft. above sea level, the average barometric pressure is about half the average pressure at sea level (see the related links for charts) However, barometric pressure also varies widely with the weather (weather charts almost always show the movement of low pressure and high pressure zones), so true barometric pressure cannot simply be calculated, but must be measured. In the United States, the National Oceanic and Atmospheric Administration provides hourly barometric readings for many locations across the country (see related National Weather Service measurement link)
Does the pressure of a gas always increases with increasing temperature?
Yes. However the volume of a gas must be constant or decreasing. If the volume is increasing then the pressure may not be increasing. For apex the answer if False.
Does the volume of a gas always increase when temperature increases and pressure decreases?
Yes. When the temperature increases the molecules are more excited and move farther apart. When the pressure decreases, the molecules also have more space and will fill the void.
What happens to entropy when pressure decreases?
When pressure decreases, entropy increases. Increases in entropy correspond to pressure decreases and other irreversible changes in a system. Entropy determines that thermal energy always flows spontaneously from regions of higher temperature to regions of lower temperature, in the form of heat.
What is the slope of a velocity vs temperature graph?
The slope of a temperature vs time graph shows the rate of change of temperature. The slope will be positive if the temperature is increasing with time and negative if it is decreasing.
How is the temperature of a gas related to its pressure?
At hIgher temperatures, the volume will be greater. This is caused by thermal expansion. As you add heat to the gas, it expands usually at a costant rate. There fore, it's volume Increases. However, it's mass will always remain constant.
What are some ways by which plants can increase their rates of photosynthesis and transpiration?
Increasing the temperature of the reaction will always increase the rate, though the actual yield will depend on whether the reaction is exothermic or endothermic. Increasing the pressure of the... Read More

What effect does an increase in temperature have on a gas's volume and pressure?
As indicated by the Ideal Gas Laws, increasing temperature will tend to increase both volume and pressure. Of course, volume can't always increase, that depends upon the flexibility or inflexibility of the container that the gas is in, and if the volume does increase that will counteract the increase in pressure that would otherwise have happened. Temperature, pressure, and volume are all interconnected in a gas.
The solubility of gases does what as temperature increases?
It usually decreases.
Is the volume of a gas directly proportional to the pressure?
The temperature
Is the average temperature on earth always the same?
Unfortunately the average temperature of the Earth is increasing. See global warming.
What is the effect of pressure o the speed of sound?
The air pressure has no effect. The static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature. The ratio p_ / ρ is always constant, on a high mountain or even on sea level altitude. That means, the ratio p_ / ρ is always constant on a high mountain, and even at "sea level". The static atmospheric pressure p_ and the density of air ρ go always together. The ratio stays constant. When calculating the speed of sound, forget the atmospheric pressure, but look accurately at the very important temperature. The speed of sound varies with altitude (height) only because of the changing temperature there.
