Which statement about the molecules in carbon dioxide gas is correct?
The molecules are close together.
The molecules are diatomic.
The molecules are in fixed positions.
The molecules move randomly.
Which statement about the molecules in ice is correct?
The molecules all move with the same speed.
The molecules are diatomic.
The molecules move randomly.
The molecules vibrate about fixed positions.
A solid metal bar is heated at one end.
How is the thermal energy transferred to the other end of the bar?
The heated molecules move along the bar, carrying all their energy to the other end.
The heated molecules move along the bar, giving energy to other molecules as they pass.
The heated molecules stay completely still but pass on their energy to other molecules.
The heated molecules vibrate more rapidly and pass on energy to other molecules.
A substance is in a state in which its particles are widely spaced and able to move freely.
It changes to a state in which its particles are in contact but still able to move freely.
What is this change called?
condensation
diffusion
freezing
evaporation
At regular intervals along a railway line there is a gap between the rail sections.
What is the reason for the gap between the rail sections?
to allow for expansion of the rail sections during hot weather
to allow for vibrations of the rail sections as the train passes over them
to allow rain water to drain from the rail sections
to keep the wheels of the train and carriages on the rail sections
Ionic compounds (like sodium chloride - table salt) have high melting points because
the ions (charged particles) are held together by strong electrostatic forces.
the ions have inert gas structures.
the electrons are attracted to the positively charged particles.
metals transfer electrons to non-metals.

According to the kinetic theory of matter, which substances are made of particles?
gases only
all matter
liquids only
all matter except solids
According to the kinetic theory of matter, how does a gas expand?
Its particles become larger.
Collisions between particles become elastic
Its temperature rises
Its particles move greater distances
The particles in a liquid are usually

Water droplets forms on a cold glass of ice tea. What state of matter WAS the water before if formed on the glass and where did it come from?
It was a liquid that leaked through the glass.
It was a gas in the air.
It was a solid in the ice cube and teleported onto the side of the glass and became a liquid.
