<p>Heat = Is the energy that transfers from a substance whose particles have a higher kinetic energy to a substance whose particles have a lower kinetic energy. Kinetic Energy = Is the energy an object has as a result of its motion. Thermal Energy = Is the total kinetic energy of all particles in a substance.

<p>Needs = Basic, required conditions necessary for survival. Wants = Include ways in which needs could be met and are not vital for survival. Standard of Living = Refers to the level of wealth, comfort, material goods, and necessities available to a society or individual. Factors influencing Standard of Living = Income, access to education and healthcare, employment opportunities, and economic conditions.</p> Signup and view all the answers
