Answer:
C. The ocean waters are heating up which leads to warmer, less dense air rising to form clouds
Explanation:
Greenhouse gases, due to their ability to trap heat, has caused an increase in the Earth's atmospheric temperature called GLOBAL WARMING. The result is that more heat is being radiated down to Earth from the sun. This could lead to hurricanes in water bodies.
Hurricanes are forceful storms that occurs when ocean waters heat up leading to warmer, less dense air that rises to form clouds. Hurricanes are called tropical cyclones.
Answer:
The pressure increases when temperature increases
Explanation:
As the temperature increases, the particles move faster, and greater speeds. That means they have greater force when they collide with the walls of the container, so the pressure increases.
Helium - 4 isotope has 2 protons and 2 neutrons.
Its atomic number is 2 (the number of protons). Atomic number is the number of protons in the atom of an element and it identifies the element. All the isotopes of an element have the same atomic number (same number of protons). So, all the isotopes of hellium have 2 protons.
The number 4 that identifies the helium - 4 isotope is the mass number, i.e. the number of protons plus the number of neutron. So, helium-4 isotope has 2 protons and 2 neutrons. While, other isotopes of helium have 2 protons but different number of neutrons.
The atomic number enable us to deduce the number of electrons in an atom because the atoms are neutral, which implies that the positive and negative charge are equal. Given that the magnitude of the charge of electons and protons are equal but the sign is opposed (protons are positve and electrons are negative) the number of electrons in the atom equals the number of protonts. That is why the atomic number is also the number of electrons of the atom.
