Back

An endothermic process is a reaction or change that absorbs heat from the surroundings.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture in which the components are not uniformly distributed and can be easily distinguished.

Front

What happens to potential and kinetic energy during a phase change?

Back

During a phase change, potential energy increases while kinetic energy remains constant.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the composition is uniform throughout.

Front

What is an example of a homogeneous mixture?

Back

Air is an example of a homogeneous mixture.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance that cannot be broken down into simpler substances, while a compound is made up of two or more elements chemically combined.

Front

What is the heating curve of water?

Back

The heating curve of water shows the relationship between temperature and the state of water as it is heated.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.
