Answer:

Heat will flow from the water in the glass to the copper until both reach the same temperature.

Explanation:

If we consider a perfectly thermal insulation in the system with glass of water at higher temperature and piece of copper at lower temperature, then when the both come in contact with each other water will lose some heat and copper will gain that heat from water. The process will continue untill both reach the same temperature. One they will reach to same temperature we will not observe any heat change or temperature change between the two.

Heat change is a function of temperature difference.

what does the number of the places after the decimal in a measurement tell you about the precision of the instrument that record
snow_lady [41]
The more numbers after the decimal point there are, the more precise the instrument which recorded it is. For example, if one instrument during seismic activity records that the magnitude of the earthquake was 2.3, and another instrument recorded that it was 2.3645, the second instrument would have shown to be more precise.

A sample of water is boiling as heat is added at a constant rate. Which statement describes the potential energy and the average
Elena L [17]
The statement which describes the potential and the kinetic energy of the water is this: THE POTENTIAL ENERGY INCREASES AND THE AVERAGE KINETIC ENERGY REMAINS THE SAME.
At boiling point of water, the heat that is been added to the water is used to break the chemical bonds that holds the molecules of the water together so that they can turn into vapour. At this point, the average kinetic energy of the water remains the same while the potential energy increases.

There are no negative consequences to using nuclear energy.
Tomtit [17]

Answer:

False

Explanation:

In Nuclear plants accidents such as explosions can occur which may lead to loss of life or severe injuries.

Nuclear energy production does not produce emissions but it produces radioactive waste which have to be stored adequately to prevent pollution. Since nuclear waste cannot be destroyed, measures have to be taken to adequately store the waste.

If the nuclear plant is being attacked, it can be used as a nuclear weapon to create disaster
