Thermodynamics

Question 1

What is thermodynamics?

Answer 1

Thermodynamics is the study of how heat (thermal energy) can be transferred between objects or transformed into other forms of energy

Question 2

What is a closed thermodynamic system?

Answer 2

A closed thermodynamic system is a container where energy can move in and out, but no mass can enter or leave. It’s like a sealed box where only energy exchanges occur, but the contents stay the same.

Thermodynamic energy is the total energy of all moving or vibrating particles in an object.

Question 3

How does thermal equilibrium occur?

Answer 3

Thermal equilibrium happens when two objects at different temperatures are brought together. Heat flows from the hotter object to the colder one until they reach the same temperature, balancing their energies.

Question 4

example of objects creating thermal equilibrium?

Answer 4

When you place a hot metal spoon into a cup of tea, heat flows from the spoon to the tea until they both reach the same temperature, creating thermal equilibrium.

Question 5

How does conduction work as an example of heat transfer?

Answer 5

Conduction: occurs when two objects at different temperatures are in contact with each other.

transfer of heat through direct contact between particles

Question 6

How does convection work as an example of heat transfer?

Answer 6

Convection: is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperatures.

Eg. boiling water on a stove
