A liquid evaporates faster at higher temperatures because more particles have a higher speed and can overcome attractions in the liquid.
Answer:
71 protons
102 neutrons
Explanation:
Step 1: Find atomic number of Lu
Lu - Element number 71
So we know that Lu has 71 protons.
Step 2: Identify Lu - 173
173 is the atomic mass number, meaning the combined number of protons AND neutrons.
173 - 71 = 102 neutrons
The metallic bond between gold atoms makes it possible to create extremely thin sheets.
Atoms of the same element or atoms from different elements can form three types of bonds:
- Covalent bonds.
- Ionic bonds.
- Metallic bonds.
In the case of metals such as gold, the most common type of bond is the metallic bond. This bond:
- Is a strong bond.
- Involves the free movement of electrons between atoms.
- Makes metals highly malleable.
These characteristics explain the reason why it is possible to create extremely thin sheets as the material will not easily break due to the strong attraction between the atoms.

Answer:
catalyst
Explanation:
Catalyst -
It is the substance that may be added to a chemical reaction , which increases the rate of the reaction , without undergoing on its chemical structure , is referred to as a catalyst.
The catalyst does not participate in the reaction, it only plays it role regarding the rate of the reaction.
Hence , the correct term for the given statement of the question is catalyst.
True because photon is a composite particle of a neutrino. It is solely based on the fact that emission and absorption of a photon corresponds to the creation of annihalation.
