Density is equal to the mass of a substance divided by its volume: density = mass of substance/volume of substance Water displacement can be used to find the volume of a solid by placing the object in a known volume of water. When the object is added to water, the measured total volume increases. This final volume is equal to the volume of the initial water plus the volume of the solid object added. To determine the volume of the...

The value of the heat capacity for a substance depends on
whether it’s measured under constant pressure conditions or
constant volume conditions. The constant-pressure molar heat
capacity is given by
= (dq/dT)P
and the constant-volume heat capacity is given by
= (dq/dT)V
Note that we use d instead of
because q is not a state function of temperature, volume, and
pressure; its value depends on how we execute the process.
Here are several questions regarding heat capacity.
a. When we...
