ICP Unit 4 (Thermodynamics) Review

Front

What is the relationship between particle speed and energy?

Back

A slower particle has a lower energy than an identical, faster particle.

Front

Which material has the lowest specific heat?

Back

Metal has the lowest specific heat compared to water, fabric, and rubber.

Front

What is commonly used in cooling systems to remove heat?

Back

Most cooling systems use a heat pump to remove heat.

Front

What does entropy refer to in thermodynamics?

Back

Entropy refers to disorder, the unusable energy that escapes a system.

Front

Which state of H2O has the greatest entropy?

Back

Vapor has the greatest entropy compared to ice and water.

Front

Define specific heat capacity.

Back

Specific heat capacity is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What is the first law of thermodynamics?

Back

The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

Front

Explain the concept of thermal equilibrium.

Back

Thermal equilibrium occurs when two objects in contact reach the same temperature and no heat flows between them.

Front

What is the significance of the heat pump in thermodynamics?

Back

A heat pump transfers heat from a cooler area to a warmer area, effectively cooling or heating a space.

Front

How does temperature relate to kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.
