Exploring Energy and Thermodynamics Concepts

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in a substance.

Front

What is temperature?

Back

Temperature is the average kinetic energy of the particles in a substance.

Front

How do balanced chemical equations illustrate conservation of mass?

Back

They show that the total mass of reactants equals the total mass of products.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the point at which two substances reach the same temperature and heat no longer flows between them.

Front

How does energy flow in a system?

Back

Energy can transform from one type to another, such as from chemical to thermal energy.

Front

What does the first law of thermodynamics state?

Back

The total energy of an isolated system is constant.

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.

Front

What is the relationship between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature measures the average kinetic energy of particles.

Front

What is an example of energy transformation?

Back

An example is a battery converting chemical energy into electrical energy.
