Temperature Vs Thermal Energy

Front

What is the difference between temperature and thermal energy?

Back

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

Front

What does thermal energy depend on?

Back

Thermal energy depends on the mass of the object and its temperature.

Front

Which has more thermal energy: a hot cup of coffee or a large iceberg?

Back

A large iceberg has more thermal energy due to its greater mass, despite the coffee being at a higher temperature.

Front

What is temperature measured in?

Back

Temperature is measured in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K).

Front

What is the relationship between temperature and kinetic energy?

Back

As the temperature of an object increases, the average kinetic energy of its particles also increases.

Front

What happens to thermal energy when ice melts?

Back

When ice melts, thermal energy is absorbed, causing the temperature to remain constant until all ice has turned to water.

Front

What is the formula for calculating thermal energy?

Back

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

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 kilogram of a substance by 1 degree Celsius.

Front

How does thermal energy transfer occur?

Back

Thermal energy transfer occurs through conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.
