Temperature, Thermal Heat & Energy Practice

Front

What is convection?

Back

Convection is a type of heat transfer that occurs in fluids (liquids and gases) where warmer areas of a liquid or gas rise and cooler areas sink, creating a circulation pattern.

Front

What is heat?

Back

Heat is the transfer of thermal energy from one object or substance to another due to a temperature difference.

Front

What is specific heat?

Back

Specific heat is the amount of energy required to raise the temperature of 1 kg of a material by 1 kelvin.

Front

What is the Fahrenheit scale?

Back

The Fahrenheit scale is a temperature scale where the freezing point of water is 32 degrees and the boiling point is 212 degrees.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a substance when it is heated, as the particles move faster and spread apart.

Front

What is conduction?

Back

Conduction is the transfer of heat through a solid material without the movement of the material itself, typically occurring in metals.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight warming the Earth.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance, indicating how hot or cold it is.

Front

What is the Kelvin scale?

Back

The Kelvin scale is an absolute temperature scale used in science, where 0 Kelvin is absolute zero, the point at which all molecular motion stops.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which a substance has minimum thermal energy, equivalent to -273.15 degrees Celsius.
