Heat and Temperature

Which cup has the MOST thermal energy if all have the same temperature?

• The small cup (Demi)

• The medium cup (Grande)

• The large cup (Trenta)

• The extra-large cup (Venti)

What is temperature?

• A measure of how hot or cold something is.

• A measure of the speed of molecules in a substance.

• A measure of the amount of heat energy in an object.

• A measure of the pressure exerted by gases.

What is heat?

• A form of energy.

• A type of temperature measurement.

• A unit of mass.

• A state of matter.

What is the difference between heat and temperature?

• Heat is a measure of how hot or cold an object is.

• Temperature is energy transferred between objects.

• Heat is energy transferred between objects, while temperature is a measure of how hot or cold an object is.

• Temperature is the total energy of all particles in an object.

What is radiation?

• The transfer of heat through electromagnetic waves.

• The process of sound wave propagation.

• The movement of particles in a solid.

• The conversion of light into chemical energy.

What is convection?

• The transfer of heat through the movement of fluids (liquids and gases).

• The process of heat transfer through direct contact between materials.

• The movement of heat through electromagnetic waves.

• The circulation of air caused by temperature differences.

What is the freezing point of water?

• -10 degrees Celsius (14 degrees Fahrenheit)

• 0 degrees Celsius (32 degrees Fahrenheit)

• 10 degrees Celsius (50 degrees Fahrenheit)

• -5 degrees Celsius (23 degrees Fahrenheit)

What is conduction?

• The transfer of heat through direct contact between materials.

• The process of heat transfer through fluids by the movement of the fluid itself.

• The transfer of heat through electromagnetic waves.

• The process of heat transfer through the movement of air particles.

What happens when something loses heat?

• It becomes colder.

• It becomes warmer.

• It remains the same temperature.

• It evaporates.

What is thermal energy?

• The energy produced by friction between two surfaces.

• The energy stored in chemical bonds of molecules.

• The total energy of all the particles in an object.

• The energy associated with the motion of an object.
