Chemistry vocab and basicsFlashcard

Front

What does the kinetic theory state about the state of matter?

Back

The state of matter changes by the speed and arrangement of particles.

Front

What are products in a chemical reaction?

Back

The new substances produced from the reactants.

Front

How do gases compare to liquids in terms of kinetic energy?

Back

Gases have more kinetic energy than liquids but less than plasma.

Front

What is a characteristic of liquids according to the kinetic theory?

Back

Liquids have a definite volume but not a definite shape.

Front

What is the role of thermal energy in phase changes of matter?

Back

It acts as the magic fuel behind all transformations, causing particles to move and change state.

Front

What is matter?

Back

Anything that has mass and takes up space.

Front

Define kinetic energy in the context of particles in matter.

Back

Kinetic energy is the energy of motion that particles possess, influencing their speed and arrangement.

Front

What is the difference between reactants and products in a chemical reaction?

Back

Reactants are the starting materials that undergo transformation, while products are the new substances formed.

Front

What happens to the kinetic energy of particles when a substance is heated?

Back

The kinetic energy of the particles increases, causing them to move faster.

Front

What is a solid's characteristic in terms of shape and volume?

Back

Solids have a definite shape and volume.
