Question

butane gas has a density of 2.54 kg/m³. air has a density of 1.22 kg/m³. does butane sink or float in air? sink float t or f water boils at 100 degrees celsius. this is a chemical property of water. true false

Explanation:

Step1: Compare densities

If the density of a substance is greater than the density of the medium it is in, it sinks. The density of butane is $2.54\ kg/m^{3}$ and the density of air is $1.22\ kg/m^{3}$. Since $2.54> 1.22$.

Step1: Identify property type

Boiling point is a physical property, not a chemical property. A physical property can be observed or measured without changing the substance's chemical identity. Chemical properties involve a change in the substance's chemical structure. Water boiling at 100 degrees Celsius is a phase - change (liquid to gas) without changing the chemical composition of water ($H_2O$).

Answer:

Sink
