Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of 1 gram of a substance by 1°C.

Front

How do you calculate heat (Q) released or absorbed?

Back

Q = m * c * ΔT, where m is mass, c is specific heat, and ΔT is the change in temperature.

Front

What is the specific heat of platinum?

Back

The specific heat of platinum is 0.133 J/g°C.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of particles in an object.

Front

Which material is the best insulator?

Back

Air is considered the best insulator among the options provided.

Front

What happens to the density of liquids as temperature decreases?

Back

The density of liquids generally increases as temperature decreases.

Front

How do you convert Celsius to Kelvin?

Back

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

Front

What is the Kelvin equivalent of -48 degrees Celsius?

Back

-48 degrees Celsius is equal to 225 K.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself.
