The molar heat capacity of gaseous heptane at 25.0°c is 165.2 j/(mol · °c). what is its specific heat?

Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by a unit degree. It is usually expressed as J/g C

In this case :

165.2 J of heat is required to raise the temperature of 1 mole of heptane by 1 C

1 mole of heptane (C7H16) = 100 g

Specific heat of heptane = 165.2/100 = 1.652 J/g C

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
