Exploring Energy and Thermodynamics Concepts

Front

What does the first law of thermodynamics state about energy in a system?

Back

Energy in a system remains constant; it cannot be created or destroyed.

Front

How does energy flow between components in a system?

Back

Energy flows from a hotter object to a cooler object.

Front

What is the charge of an electron?

Back

The charge of an electron is negative.

Front

What is conduction in terms of energy transfer?

Back

Conduction is the transfer of energy through direct contact between particles.

Front

How is the conservation of mass demonstrated in a chemical reaction?

Back

The mass of the reactants equals the mass of the products.

Front

What is thermodynamics?

Back

Thermodynamics is the study of energy, heat, and work, and how they interact.

Front

Define 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

Explain the concept of thermal equilibrium.

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, as they are at the same temperature.

Front

What is the difference between an endothermic and exothermic reaction?

Back

An endothermic reaction absorbs heat, while an exothermic reaction releases heat.
