What happens if hydrogen molecules and oxygen molecules are at the same temperature?

So when two gases are at the same temperature, their molecules have the same average kinetic energy. Since they are at the same temperature the average kinetic energy of H2 must be equal to the average kinetic energy of O2, then the H2 molecules must be moving, on average, faster than the O2 molecules.

What is the relationship between volume and the number of moles of a gas?

Avogadro’s law states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.” For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

Which of the following is a mathematical representation of the relationship of volume and the number of moles when pressure and temperature is held constant?

The equations describing these laws are special cases of the ideal gas law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, T is its kelvin temperature, and R is the ideal (universal) gas constant.

What is Avogadro’s volume?

The volume occupied by one gram-mole of gas is about 22.4 litres (0.791 cubic foot) at standard temperature and pressure (0 °C, 1 atmosphere) and is the same for all gases, according to Avogadro’s law. …

Why do hydrogen molecules move faster than oxygen?

The hydrogen molecules move faster than oxygen molecules at the same temperature, since the oxygen molecule is 16 times heavier than the hydrogen molecule.

Why don t all the gas particles move with the same speed at a given temperature?

The volume of the gas does not depend on the size of the molecules that make it up. Since all gases have the same average kinetic energy at the same temperature, lighter molecules move faster and heavier molecules move slower on average.

What relationship exists between the volume and the number of moles Brainly?

A plot of the effect of temperature on the volume of a gas at constant pressure shows that the volume of a gas is directly proportional to the number of moles of that gas. This is stated as Avogadro’s law.

What is the relationship between the amount of gas indicated by moles and volume directly or indirectly proportional?

At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas.

What is the mathematical relationship between temperature and pressure direct or inverse?

The pressure (P) of gas is directly proportional to its temperature ( T, measured in kelvins). This means that when we hold amount and volume of gas constant, the pressure of gas will increase as its temperature increase. Mathematical, we can express this relationship as: P ∞ T. P/T = K.

Whats the relationship between temperature and volume?

Charles’s law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant.

What does R mean in PV nRT?

PV = nRT. The pressure of a gas times its volume equals the number of moles of the gas times a constant (R) times the temperature of the gas.

Do all gases at the same pressure and temperature have the same density?

The mass density of a gas is typically just called the “density”. Because gases that are behaving ideally under the same conditions (temperature, pressure) all have the same number density, they will all have different mass densities since different gases have different masses per particle.

Which gas is kept at the same temperature and pressure?

100 mL O2 and H2 kept at same temperature and pressure. BITSAT 2018: 100 mL O2 and H2 kept at same temperature and pressure. What is true about their number of molecules (A) NO2 > NH2 (B) NO2 < NH2 (C)

How many molecules are there in 100 ml of gas at STP?

As per the question, the volume of each gas is equal at STP. Therefore, the number of molecules in 100 ml of each of gas at STP are the same. Was this answer helpful?

What is the mass of the heaviest molecule?

CO2; according to Avogadro’s Hypothesis, they all contain the same number of particles, therefore, the heaviest molecule, CO2 (molar mass = 44), will have the greatest mass. all the same; at the same temperature all gases have the same kinetic energy.
