Grade 1 Thermodynamics Quiz

What is thermodynamics?

• Branch of physical science dealing with heat and energy

• Branch of mathematics

• Study of marine life

• Type of computer programming language

What is the study of heat and energy transfer called?

• chemistry

• thermodynamics

• biology

• geography

What are the basic principles of thermodynamics?

• First law, second law, and third law

• North, south, east

• Addition, subtraction, multiplication

• Red, blue, green

What is the zeroth law of thermodynamics?

• The zeroth law of thermodynamics states that energy cannot be created or destroyed

• The zeroth law of thermodynamics is about the relationship between pressure and volume

• The zeroth law of thermodynamics is related to the conservation of mass

• If two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.

What is meant by thermal equilibrium?

• The state in which objects never reach the same temperature

• The state in which two objects have different temperatures

• The state in which two or more objects or substances in contact with each other reach the same temperature.

• The state in which objects reach extreme temperatures

How can you apply the zeroth law of thermodynamics in everyday life?

• Using a ruler to measure the length of an object

• Using a compass to find the direction

• Using a calculator to solve math problems

• Using a thermometer to check if different objects have the same temperature

What happens when two objects are in thermal equilibrium?

• There is no net flow of heat between them.

• One object becomes hotter than the other

• They start to vibrate rapidly

• They repel each other due to heat

Give an example of the zeroth law of thermodynamics in action.

• Two cups of coffee left on a table will eventually reach the same temperature as the room, demonstrating thermal equilibrium.

• A hot air balloon rising in the sky

• A car engine heating up after being turned on

• A block of ice melting in a warm room
