Answer:
A) a scientific theory or principle
Explanation:
A Theory or principle has to explain different observations for a specific phenomenon. Theories are tested in base of new data to see if they can fit with all the new variations. They gain more acceptance in the scientific world if they predict in a correct way the result of many observations.
For example the uncertainty principle which state that the position and the momentum of a particle can not be known at the same time. Many experiments that aim to test the Uncertainty principle demonstrated this property, but tests are currently being done with other variations to see if the principle still fits with them.
The heat transfer that we'll have will be:
- At first, the metal bar will emanate heat through radiation, to the atmosphere, and to the second metal, through conduction.
- Because of this, the second bar will start to increase it's temperature, up to the fusion point, spending the energy received on the fusion, and also radiating heat to the atmosphere. It won't emit heat in any other form, since heat transmission can happen only from a hot body to a cooler one, and the only things in contact are the two bars.
Answer:
A ratio is a way to compare quantities of things.
Explanation:
by dividing the number of moles of each by the smallest number of moles.
Answer:
C. loses heat, temperature decreases
Explanation:
When gas condenses, energy decreases, therefore it would lose heat and the temperature would decrease.
Weight is the object's mass times the force of gravity acting upon it. If a .5 kg object weighs 11.5 N on Jupiter, it's acceleration of gravity would be 11.5/.5 which is 23 meters per second squared.
