There would be 79 electrons present in each atom of gold. I hope this helps :)
Accuracy is the closeness of a measurement to its true value. Precision is the closeness of more than one measurements to each other. The measurements of Lamant is both accurate and precise while the scale of Colin is the opposite. Kirvin is precise but he is not accurate.
<span>renewable resources are used primarily to produce electricity include wind and hydro-electric power. they require large mechanical structures e.g. wind turbine and water dam in order to generate electric energy. Therefore they are not appropriate for home use.
</span><span>renewable resources are readily used as heat sources for homes include solar-water heating system in which water is heated by sunlight and circulated around the house. Wood burning for heat can also be considered a renewable resource as long as the wood comes from a sustainable logging cycle.</span>
Answer:
2.At a given temperature, the KE of all gases is the same.KE depends only on Kelvin temperature
Explanation:
The kinetic molecular theory of gases provides a succint expalantion and insight into the behaviour of gases. The assumptions of the theory are stated below:
- Gases are made up of large number of identical molecules which are moving at different speeds.
- Spaces occupied by molecules of gases are negligible compared to the volume of the container.
- Molecules of gases are independent of one another.
- The molecules collide with themselves and the walls of the container elastically.
- The temperature of a gas is a measure of only the average kinetic energy of the molecules.
