Asample of gas is enclosed in a container of fixed volume, identify which of the following statements are
true. check all that apply.
if the container is heated the gas particles will lose kinetic energy and temperature will increase.
if the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.
if the gas particles move more quickly, they will collide more frequently with the walls of the container
and pressure will increase.
if the gas particles move more quickly, they will lose energy more rapidly and collide with the walls of
the container less often, and pressure will decrease.
if the gas particles move more quickly, they will collide with the walls of the container more often and
with more force, and pressure will increase.

If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.

If the gas particles move more quickly, they will collide more frequently with the walls of the container  and pressure will increase.

If the gas particles move more quickly, they will collide with the walls of the container more often and  with more force, and pressure will increase.

Explanation:

The temperature of gases is a measure of the average kinetic energy of the molecules. With increasing temperature comes more kinetic energy for the gaseous particles. If temperature of the system is reduced, the particles will have less kinetic energy and would not be able to move. Temperature is directly proportional to average kinetic energy.

Pressure of gases increases when there is more frequent collision between their particles. The usual case is for gases to move more rapidly as a result of increase in kinetic energy of the system. The particles collides more frequently with one another and the walls of the container if the kinetic energy is raised.

gravity causes stares to cluster i think so

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
