SET 8

Front

What are the phase changes mentioned in the text?

Back

Melting and vaporization, along with their reversals.

Front

What is latent heat (L)?

Back

Energy absorbed to break molecular bonds without raising temperature.

Front

What is the latent heat of fusion (L_f) for ice?

Back

Approximately 330,000 J/kg.

Front

What is the latent heat of vaporization (L_v) for water?

Back

About 2.3 × 10^6 J/kg.

Front

What process does the latent heat of vaporization govern?

Back

Boiling processes, converting liquid water at 100 °C to steam.

Front

Why is latent heat important for steam engine efficiency?

Back

It absorbs large energy amounts during the conversion of water to steam.

Front

What happens during freezing and condensation in terms of latent heat?

Back

They release latent heat, affecting climate and weather.

Front

How does latent heat affect storm development?

Back

When water vapor condenses in the atmosphere, it warms surrounding air, fueling storm development.

Front

Why is accurate knowledge of latent heats vital?

Back

It's important for refrigeration cycle design, meteorology, and energy balance assessments in natural and engineered systems.
