Which statement is true about nuclear decay
Readme [11.4K]

Answer:

Nuclear decay rates are constant

Explanation:

Spontaneous decay of unstable nuclei is a process of a statistical nature, it is not possible to predict with certainty when an individual radioactive nucleus will decay, nor can the decay process be influenced in any way.

Therefore, the half-life of radionuclides (specific for each radionuclide) is defined as the time period in which half of the initial number of radioactive nuclei decays.

The unit of measurement for the radioactivity of the material is the becquerel (Bq) and denotes the number of decays in one second (1Bq = 1 decay / 1 second).

Which of the following locations will be relatively warmer during summers, and why? An inland location, because water heats up f
Katen [24]

Answer:

An inland location, because land has lower specific heat than water

Explanation:

The specific heat is a measure of how much heat must be supplied to warm up a substance by a certain number of degrees.

Water has a much higher specific heat than land, so it takes much more heat energy to heat up a given mass of water compared to the land.

To say it another way, the specific heat of land is much less than that of water, so it doesn't take as much heat energy to warm up the land.

Thus, an inland location will be relatively warmer during summers.
