The first law of thermodynamics states energy is not created or destroyed, so why must we ensure that the energy resources of the planet are conserved?

Energy transforms, sources of energy that we are using now are non renewable.

Explanation:

What this states that for example a big portion of the fuel and sources of energy we are using now are non renewable, examples of these are Oil, or petroleum based fuels, or carbon based industries, this are highly contaminating and can´t be renewable, like other "clean" energies, or energies that do not create carbon emissions and are available like nuclear, solar, eolic or others.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

so easy. just google the electromagnetic waves and it’ll pop up.
