Heat, Temperature & Thermal Energy

Front

What is the direction of thermal energy transfer?

Back

Thermal energy ALWAYS moves from hot to cold.

Front

What is the temperature in degrees Kelvin if the average daytime temperature on Venus is 453°C?

Back

726K

Front

What is the SI unit of heat and energy?

Back

The SI unit of heat and energy is the joule.

Front

What type of energy transformation occurs when a kid eats spaghetti and then plays with toys?

Back

The energy transformation is from chemical energy to mechanical energy.

Front

What type of energy is associated with motion?

Back

Energy due to motion is called kinetic energy.

Front

What is the difference between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature is a measure of the average kinetic energy of particles in a substance.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

Front

What is the formula to convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is specific heat capacity?

Back

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