Q4. Pressure on the surface of a gas is increased. What will happen to the inter particle forces?
Q5. A gas can exert pressure on the walls of the container. Give reason.
Q6. Convert the following temperature to Kelvin Scale- (a) 100°C (b) -100
Q7. What is meant by density?
Answers
1) Increase in the pressure on the surface of a gas decreases the volume of the gas with increasing its density. The particles start moving in straight lines and also collide with the wall of the container and this collision enhances the inter particle forces and increases the fluidization behaviour.
2) The pressure exerted by a gas is due to the random motion of particles in the gas. Gases have weak intermolecular forces and the particles in continuous random motion and these particles collide with the walls of the container. These collisions with the walls of the container exerts pressure on the gas.
3) sorry I didn't now siso
4) Density, mass of a unit volume of a material substance. ... Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).
