Whats the relationship between the temperature and the density of a substance

Temperature Effects on Density. Density is a physical property of substances that compares the relationship between volume and mass. Density is affected by temperature because as temperature increases so does the kinetic energy of the particles.

Explanation:

i'm not sure

explanation:

i'll try whatever you got

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
