increasing the number of gas molecules
What does Charles's law state? *
1 point
At constant temperature, a gas pressure increases, so does the volume.
At constant pressure, as the temperature of a gas increases, so does the volume.
At constant volume, as the gas pressure increases, the temperature decreases.
At constant volume, as the gas pressure increases, so does the temperature.
A chemist heats a gas within a sealed, rigid container. Which statement describes the changes that occur in the gas? *
2 points
The gas particles move slower and hit the sides of the container with less force, consequently, the pressure increases.
The gas particles move faster and hit the sides of the container with more force, consequently, the pressure increases.
The gas particles move slower and hit the sides of the container with less force, consequently, the pressure decreases.
The gas particles move faster and hit the sides of the container with more force, consequently, the pressure decreases.
