If the temperature of a fixed amount of gas is increased at a constant pressure what will happen to a volume?

Volume will increase. Think of it this way. If you heat a gas, it gets hotter. When a gas gets hotter, the atoms/molecules are "more active" and the pressure and/or the volume will go up. If your experiment with heating this gas sample must have a constant pressure, then volume will have to increase to give all those "more active" atoms/molecules more play room to prevent the pressure from going up.

∙ 12y agoIn an ideal gas the prouct of pressure and volume equals a constant times the absolute temperature, i.e. PV = RT, where R is called the universal gas constant. If the pressure is constant then this equation, in effect, becomes V= k'T where k' = R/P.
This means that the volume will increase in proportion to the value of the absolute temperature with the constant of proportionality being R/P.
The reason the volume expands is because the gas molecules receive energy from the increase in temperature and this energy will mean that if the pressure is to remain constant, the volume occupied by the gas will have to increase

What will increase the volume of gas?
change the pressure and/or the temperature of the gas
What factors affect the pressure of enclosed gas?
temperature
What are specific variables for Charles and Boyles laws?
1. A more correct name is Boyle-Mariotte law, because Mariotte discovered this lawafter Boyle but indepedently.. 2. This law is a relation between pressure and volume at constant temperature. The equation is: pV = k where p is the pressure (variable), V is the volume (variable) , k is a constant specific for the system.
The Combined Gas Law deals with what quantities?
The combined gas relates the variables of pressure (P), volume (V), temperature (T), and molar amount (n). The equation relating these four variables is the Ideal Gas Law of PV = nRT, where R is the Ideal Gas Constant.
Does a balloon show that air can be compressed?
Yes, a balloon shows that air can be compressed. The pressure in the balloon is higher than the pressure outside the balloon. The ideal gas law is PV = nRT where: P = pressure V = volume n = the number of moles of gas (the amount of gas) R = the ideal gas constant T = temperature So for the given volume of the balloon, and at a set temperature, if the pressure goes up, the amount of gas (the number of moles) must also go up. That means that the gas has been compressed.
How can the volume of gas be increased if the pressure is constant?
I wonder that by increasing temperature it will lead to a higher pressure.
What is the effect of the temperature on the vapour pressure?
When temperature is increased the amount of molecules evaporated is increasef and as a consequence condensation is also increased so vapour pressure increases.
What happens to the pressure of a gas if the volume increases?
It will increase? No it will decrease when the same amount of gas is held at constant temperature.
What is the temperature if the gas pressure is constant?
At isobaric (pressure) expansion (volume increase) the temperature will increase because V is proportional to T for the same amount of gas (closed container) at constant pressure.
At constant pressure if the temperature of a given amount of gas increases then the volume must do what?
increase
What must remain constant for pressure and temperature to be directly proportional?
volume and amount of a gas.
What happens when pressure falls and temperature rises?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.
What happens when a given amount of gas at a constant temperature increases in volume?
In this case the pressure decrease.
What happens when a given amount of gas at a constant temperature increases volume?
In this case the pressure decrease.
When the pressure on a gas increases at constant temperature its volume?
decreases
What does Boyle's Law state?
Gases Boyle's law states that the Volume of a given amount of gas at constant Temperature varies inversely proportional to Pressure. You have a given volume of gas, and you double its pressure keeping Temperature constant, the volume will reduce by half.
What is the pressure of the air in ATM in the lungs when the gas expands to 195.0 ml at a body temperature of 37 degrees C and the amount of gas 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.
