Final Test Thermal Energy Amplify

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, which depends on both the temperature and the number of particles.

Front

Which has more thermal energy: a small cube of ice at 0°C or a large cube of ice at 0°C?

Back

The large ice cube because it has more particles than the small ice cube.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by uneven heating.

Front

How does heat transfer occur in an iron?

Back

Heat transfers to clothing through conduction, which is the direct transfer of heat between materials that are in contact.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

What is the role of kinetic energy in thermal energy?

Back

Kinetic energy is the energy of motion; in thermal energy, it refers to the movement of particles, where faster-moving particles indicate higher thermal energy.

Front

What happens to thermal energy when ice melts?

Back

When ice melts, thermal energy is absorbed from the surroundings, causing the ice to change from solid to liquid.

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 an example of radiation?

Back

An example of radiation is the heat from the sun warming the Earth, which occurs without direct contact.

Front

How does uneven heating affect air circulation?

Back

Uneven heating causes air to circulate as it attempts to find equilibrium, leading to weather patterns and wind.
