What is the formula for calculating density?

Back

Density (D) = Mass (m) / Volume (V)

Front

What is the unit of measurement for density?

Back

g/cm³

Front

If a rock has a mass of 14g and a volume of 2cm³, what is its density?

Back

7 g/cm³

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

What is the specific heat of copper?

Back

0.39 J/g °C

Front

How do you calculate the temperature change (∆t) when heat is added?

Back

∆t = Q / (m * c), where Q is heat added, m is mass, and c is specific heat.

Front

What is the temperature scale used in gas laws?

Back

Kelvin

Front

What is the specific heat formula?

Back

Q = m * c * ∆t

Front

If 100 Joules of heat is added to 20 grams of copper with a specific heat of 0.39 J/g °C, what is the temperature change?

Back

12.82 °C

Front

What is the relationship between mass, volume, and density?

Back

Density is directly proportional to mass and inversely proportional to volume.
