Front

What force holds a comet together and governs its motion?

Back

Gravitational force holds a comet together and governs its motion as it orbits.

Front

What is conduction? Provide an example.

Back

Conduction is the transfer of heat through direct contact. An example is placing ice into a glass of water to chill it.

Front

Why are most asteroids irregularly shaped?

Back

Most asteroids are irregularly shaped due to weak gravitational pull caused by their small size.

Front

What happens when two bodies of water at different temperatures reach thermal equilibrium?

Back

When two bodies of water at different temperatures reach thermal equilibrium, the temperature throughout the container will be approximately the average of the two temperatures.

Front

Define gravitational force.

Back

Gravitational force is the attraction between two masses, which governs the motion of celestial bodies.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two bodies in contact with each other reach the same temperature.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

What is the role of gravity in the formation of celestial bodies?

Back

Gravity pulls matter together to form celestial bodies, influencing their shape and motion.

Front

What is the significance of nitrogen in the atmosphere?

Back

Nitrogen is essential for life as it is a key component of amino acids and proteins.
