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 energy transfer?

Back

Energy transfer is the movement of energy from one object to another.

Front

What happens during thermal equilibrium?

Back

Energy is transferred between two objects until they reach the same temperature.

Front

What is the ability to do work or cause change called?

Back

Energy.

Front

What is the relationship between temperature and thermal energy?

Back

Temperature is a measure of the average kinetic energy of particles, while thermal energy is the total energy of all particles.

Front

What is heat?

Back

Heat is the energy that is transferred between objects due to a temperature difference.

Front

What occurs when two objects at different temperatures come into contact?

Back

Energy will transfer from the warmer object to the cooler object until they reach thermal equilibrium.

Front

What is the significance of particle movement in thermal energy?

Back

The movement of particles affects the thermal energy; faster-moving particles indicate higher thermal energy.

Front

What is the formula for calculating thermal energy?

Back

Thermal energy can be calculated using the formula: Q = mcΔT, where Q is thermal energy, m is mass, c is specific heat capacity, and ΔT is the change in temperature.
