Alpha particles cannot penetrate deeply into solids because they have low velocity. This should be correct. :D
The temperature of the ice will go up from negative whatever to 0 Celsius. Then, it will use up energy to melt (this is what we call heat of fusion).
The temperature will then go from 0 to 100. Once it reaches 100, it will use up energy to vaporize (this is what we call heat of vaporization).
Answer:
physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change
The difference between Argon-38 and Argon - 45 is the number of neurons in their nuclei.

What is Isotope?</h3>
Isotopes are two or more types of atoms of the same element that have the same atomic number but differs in mass numbers due to different numbers of neutrons in their nuclei.
Argon atom with a mass number of 38 (Ar-38) - number of neutrons = 20
Argon atom with a mass number of 45 (Ar-45) - number of neutrons = 27
Thus, the difference between Argon-38 and Argon - 45 is the number of neurons in their nuclei.
