When a piece of aluminum foil is taken out of the oven and cools from 100° to 50°, what is the change in temperature?

Back

50°

Front

If the specific heat of water is 4,184 J/g∙°C, how much heat is required to increase the temperature of 1200 g of water from 23 °C to 39 °C?

Back

80,371.2 J

Front

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

Back

Largest cup (Trenta)

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

What is the formula for calculating heat energy?

Back

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

Front

What does a high specific heat indicate about a substance?

Back

It requires more energy to change its temperature.

Front

What is thermal energy?

Back

The total kinetic energy of all the particles in a substance.

Front

How does the specific heat of water compare to metals?

Back

Water has a higher specific heat than most metals, meaning it can absorb more heat without a significant temperature change.
