which substances are gaseous at room temperature?

which substances are liquid at room temperature?

which substances are solid at room temperature?

which substances are liquid at -10 oC?

which substances are liquid at 150 oC?

oxygen only

sodium

Multiple Select

which statements below describe the solid?

particles are arranged in lattice

strong forces hold the particles together

particles are sliding each other

weak forces hold the particles together

small movement of particles such as tiny vibration

Match

Match the following

characteristic in liquid

arrangement

speed of particles

forces of attraction

movement

particles are close each other but not in lattice

particles can move about in average speed

less strong compared to solid

slide to each other

Match

Match the following

characteristic in gas

arrangement

speed of particles

forces of attraction

movement

particles are very far apart

particles move very fast

almost no forces holding particles together

quick moving

Reorder

Reorder what happens when melting

particles in solid absorb energy

as there is energy intake, particles vibrate more vigorously

particles will expand

at its melting point, force of attraction will be broken

particles will start sliding over each other

Multiple Select

which statements describe the boiling process?

particles will collide more often and bounces further apart

energy is taken in to break the force of attraction between particles

liquid particles expand

particles keep sliding over each other

particles will start moving vigorously

Open Ended

compare evaporation and boiling in 3-5 sentences

Type response here

Reorder

Reorder what happens when freezing

particles in solid releases energy

as there is energy loss, particles move slower

particles will get closer to each other

particles start to bond to each other on its freezing point

Reorder

Reorder what happens when condensation

particles in solid releases energy

as there is energy loss, particles move slower

particles will get closer to each other

particles start to bond to each other on its condensation point

Multiple Choice

what is the freezing point of the substance?

200oC

150oC

100oC

50oC

Multiple Choice

what best explains from B to C?

Water vapour loss energy, change the gas into liquid

Water vapour gain energy, change the gas into liquid

Water vapour gain energy, change the liquid into gas

Water vapour loss energy, change the liquid into gas

closer look about the gas

Multiple Choice

Which of the following best defines gas pressure?

The amount of heat energy a gas absorbs in a given volume.

The force exerted by gas particles per unit area on the walls of a container.

The volume occupied by a gas in a sealed container.

The temperature of a gas in relation to its kinetic energy.

Multiple Select

what happens when temperature of the gas increases? (tick all of the correct statement)

more gas pressure

particles move vigorously

volume of gas increases

volume of gas decreases

Multiple Choice

what happens when pressure is increased?

Density increases and volume decreases.

Density decreases and volume increases.

Temperature decreases and volume increases.

Volume increases and density decreases.

Multiple Choice

Hydrogen sulfide, H₂S, and hydrogen chloride, HCl, are both gases at temperatures above –50 °C.

Which gas will diffuse most rapidly at the temperature given?

hydrogen chloride at –40 °C

hydrogen chloride at –20 °C

hydrogen sulfide at –40 °C

hydrogen sulfide at –20 °C

Multiple Choice

which of the following statement is correct related to rate of diffusion of gas?

Lighter gases diffuse faster than heavier gases.

Diffusion rate is solely determined by the color of the gas.

The rate of diffusion is not affected by the weight of the gas.

Heavier gases diffuse faster than lighter gases.
