direct proportionality because then the pressure of the gas is constant. Gay Lussac's law clearly states that the volume of an enclosed gas is directly proportional to the absolute temperature of the gas, provided that the pressure remains constant.

Do Gases have a definite shape and volume true or false?
False. Gases in a container take the shape of the container. The volume of a gas increases with temperature and inversely with pressure, except when in a closed container where volume remains the same as the volume of the container and the temperature and pressure will vary.
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.
Why do liquids and gases expand when they are heated?
By heating the gas, you are adding energy to the particles, and as a result, they will move faster and with more force. If the gas does not have room to expand (set volume), then the pressure will increase because temperature and pressure vary directly. But when there isn't a set volume, the particles will bounce off each other (with more force) and get further apart from each other.
Do gas have melting point?
Yes, they have. They are gaseous at room temp. but at some temperature they are liquid as well as solid. For example :- Methane has Melting point -182.5 °C, 91 K, -297 °FBoiling point -161.6 °C, 112 K, -259 °F
When you are measuring the volume of water in a graduated cylinder do you look at the top of the meniscus or the bottom of the meniscus?
You measure from the bottom of the meniscus. The top of the meniscus can vary wildly depending on the diameter of the tube, or the air pressure, or room temperature.
At constant pressure how does the volume of 1 mole of an ideal gas vary?
The volume varies inversely with pressure.
How are gas volume and gas pressure related?
PV=RT, Pressure and Volume are inversely related, P=K/T.
How does the volume of a gas vary?
Pressure and temperature. As pressure increases, volume decreases; as temperature increases, volume increases with it. At standard temperature and pressure (1 atm, 273 degrees Kelvin), one mole of a gas (6.022 x 1023 particles) has the volume of 22.4 liters.
Do Gases have a definite shape and volume true or false?
False. Gases in a container take the shape of the container. The volume of a gas increases with temperature and inversely with pressure, except when in a closed container where volume remains the same as the volume of the container and the temperature and pressure will vary.
How does the gas volume vary with change in pressure?
This one is explained in Boyle's Law. It was stated that if the temperature is constant, the pressure is inversely proportional to the volume. Thus, if the pressure increases, the volume decreases. It is also the same as if the pressure decreases, the volume of the gas increases.
How does air pressure vary?
Inversely with altitude, the higher up you go the less air pressure
What is the difference between directly propotional and inversely proportional?
In directly proportional the two variable vary in the same "direction". So, if one increases, the other increases.In inversely proportional, the two variable vary in opposite "directions". So, if one increases, the other decreases.
How many iron nails can be lifted by the magnets?
That will vary inversely with the size/weight of the nails and directly with the strength of the magnet.
What is the relationship between the volume and pressure of a gas when temperature is held constant?
The pressure and volume are related because both are variable of indefinite which means that both are not positive or definite and they tend to vary by the object they are in.
What is the opposite of definite in volume?
The opposite of definite in volume (solids and liquids) would be indefinite in volume, as in gases, which can vary in volume for a given mass (pressure).
How can you tell the difference between a graph in which one variable is directly proportional to another and a graph in which two variables vary inversely?
1. You can tell the difference because the proportional one has the same slope while the inversely one has opposite reciprocal slope.
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.
