Chemistry

Compared to a sample of helium at STP, the same sample of helium at a higher temperature and a lower pressure

Behaves more like an ideal gas

A sample of gas is in a rigid cylinder with a moveable piston the pressure of the gas is kept constant if the kelvin temperature of the gas is doubled the volume of the gas is

Doubled - gas expands when it is heated. Doubled the kelvin temp to double volume

The kinetic molecular theory states that all particles of an ideal as are

In random constant straight-line motion

When a sample of a gas is heated in a sealed rigid container from 200K to 400K the pressure exerted by the gas is

Increased by a factor of two If temperature is doubled pressure is doubled

When a sample of gas is cooked in a sealed rigid container the pressure the gas exerts on the walls of the container will decrease because the gas particles hit the walls of the container

Less often and with less force

A real gas behaves most like an ideal gas at

Low pressure and high temperature

Which phase describes the notion and attractive forces of ideal gas particles

Random straight line motion and no attractive forces

A sample of a gas is sealed rigid container that maintains a constant volume. Which changes occur between the gas particles when the sample is heatedc

The frequency of collisions increases and the force of collisions increase - heat raises temperature - temperature measures average kinetic energy - kinetic energy is energy of motion
