Specific Heat

Front

What is specific heat?

Back

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

Front

Which material is the best insulator?

Back

Air is considered the best insulator among common materials.

Front

How many Joules of energy are required to melt 100 grams of ice at 0°C?

Back

30,000 Joules are required to completely melt 100 grams of ice at 0°C.

Front

In which direction does heat flow?

Back

Heat flows from warmer objects to cooler objects.

Front

What does temperature measure in terms of molecular activity?

Back

Temperature measures the average kinetic energy of the molecules in a substance.

Front

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

Back

Carbon Steel would be the coolest after being heated.

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.

Front

What is the specific heat of water?

Back

The specific heat of water is approximately 4.18 J/g°C.

Front

Why is water considered a good coolant?

Back

Water is a good coolant because it has a high specific heat, allowing it to absorb a lot of heat without a significant rise in temperature.

Front

What happens to the temperature of a substance during a phase change?

Back

The temperature of a substance remains constant during a phase change, even though heat is being added or removed.
