Kinetic Theory

Question 1

which type of particles are not attracted to each other?

Answer 1

Gas Particles

Question 2

Particles in which state of matter have the highest energy?

Answer 2

Particles of gases have more energy than liquids or solids. Ice has less energy than liquid water.

Question 3

Which states of matter are fluids?

Answer 3

Liquids and gases

Question 4

In which state of matter are the particles closest together?

Answer 4

Solid

Question 5

Which states of matter increase in size when heated?

Answer 5

All three states of matter (solids, liquids and gases) expand when heated. Solids and liquids do expand less than gases when heated.

Question 6

What type of energy do particles obtain when heated?

Answer 6

Kinetic

Question 7

What shape are changes of state in a heating curve?

Answer 7

Horizontal

Question 8

How is evaporation different from boiling?

Answer 8

It occurs at any temperature

Question 9

How is the arrangement of particles in a solid different from those in a gas?

Answer 9

Particles in a solid are arranged regularly. They are randomly arranged in a liquid. They are further apart in a gas not a solid.
