:) The relationship between heat, pressure, density, and temperature in a substance is known as . Fill in the blank please

A given block of material has a temperature, a volume, and a weight.

The density can be calculated from the weight and volume, D = wt/volume

The weight and temperature is a measure of the heat energy contained in the mass,

If the temperature is raised, the heat energy in the mass in increased.

If the temperature is raised the material will expand and the volume increased and the density decreased.

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !
