Thermodynamics and Heat Transfer

Flashcards about thermodynamics and heat transfer concepts.

Why does a car engine heat up when running?

Combustion and friction transfer thermal energy.

Why do firefighters wear heat-resistant suits?

To block thermal energy transfer.

How does the Second Law of Thermodynamics relate to the melting of glaciers?

Heat from the environment transfers to the ice, causing it to melt.

Why do astronauts need cooling systems in their space suits?

Space has no air for convection.

If a spacecraft enters Earth's atmosphere at high speed, why does it heat up?

Air resistance and friction create thermal energy.

The phase change where a solid turns directly into a gas is called

sublimination
