Q

Front

When a metal cube at 70°C is immersed in water at 20°C, what happens to the heat?

Back

The metal loses heat while the water gains heat.

Front

Which material would be the coolest after being heated with the same thermal energy: Copper, Stainless Steel, Carbon Steel, or Zinc?

Back

Carbon Steel

Front

What happens to heat flow when two objects at different temperatures come in contact?

Back

Heat flows from the warmer object to the cooler one until they both have an equal temperature.

Front

For a skillet used for cooking, do you want a high or low specific heat?

Back

Low, so that it will change temperature quickly.

Front

Define specific heat capacity.

Back

The amount of heat required to raise the temperature of 1 kg of a substance by 1°C.

Front

What is the specific heat of water?

Back

4.18 J/g°C.

Front

How does specific heat affect temperature change in materials?

Back

Materials with low specific heat change temperature quickly, while those with high specific heat change temperature slowly.

Front

What is thermal equilibrium?

Back

The state in which two objects in contact reach the same temperature.

Front

What is the formula for calculating heat energy (Q)?

Back

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