What else can I help you with?
Does the volume of a gas always increase when temperature increases and pressure decreases?
Not necessarily. The volume of a gas is directly proportional to temperature and inversely proportional to pressure, according to the ideal gas law. If the temperature increases and pressure decreases proportionately, the volume would remain constant.
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 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.
What is always increasing and decreasing at the same time?
Your age, as it increases each year but decreases with each passing day.
How volume and pressure related?
Pressure and Volume are indirectly propotional to each others. if you increase the Area the pressure will be decresed, and if you decrease the area of the applied pressure, the pressure will be automatically increased, Hence. Pressure if Indirectly propotional to Area.
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 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.
Weather element that always decreases with increasing height?
Pressure always decreases with height. This is because atmospheric pressure is just a measure of how much air is weighing down. So the higher you go in the atmosphere, the less air is above you (more of it is below you) and the lower the pressure will be.

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.
The solubility of gases does what as temperature increases?
It usually decreases.
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 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.
Is the volume of a gas directly proportional to the pressure?
