Question

8 elección múltiple 1 punto a student notices that a gas will expand to fill any container it is put in. which statement correctly explains this property of gases? gases have very weak attractions between particles. gases have very strong attractions between particles. gas particles are smaller than solid or liquid particles. gas particles do not move. 9 fórmula 1 punto convert 4780.7 mmhg to atm. (1 atm = 760 mmhg) round to 1 decimal place respuesta 10 elección múltiple 1 punto which of the following statements is false? gases are assumed to have no attractive forces between particles. average kinetic energy of gas particles is directly related to the kelvin temperature. all gas particles in a sample move at the same speed. gas pressure results from collisions of gas particles with the sides of the container.

Explanation:

Question 8

Gases have weak inter - particle attractions, allowing them to expand and fill containers. Strong attractions would keep them more confined, particle size doesn't explain expansion to fill a container, and gas particles are in constant motion.

Step1: Set up conversion formula

Use the conversion factor $1\ atm = 760\ mmHg$. Let $x$ be the pressure in atmospheres. The formula is $x=\frac{4780.7}{760}$.

Step2: Calculate the value

$x=\frac{4780.7}{760}=6.289078947$.

Step3: Round to 1 decimal place

Rounding $6.289078947$ to 1 decimal place gives $6.3$.

Gas particles in a sample have a distribution of speeds due to the Maxwell - Boltzmann distribution. Gases are assumed to have no attractive forces in the ideal gas model, average kinetic energy is related to temperature, and gas pressure is from particle - container collisions.

Answer:

Gases have very weak attractions between particles.
