Answer:
Melting is the process of being changed from a solid to a liquid state especially by the application of heat. This occurs when the energy of the solid increases, which increases the substance's temperature to the melting point. Typically, the solids energy increases by the application of heat or pressure. At the melting point, the ordering of molecules in the solid breaks down to a less ordered state, and the solid "melts" to become a liquid.

Answer:
Average Atomic Mass = 10.81
Explanation:
Data Given:
Atomic Mass of ¹⁰X = 10 amu
Relative Intensity of ¹⁰X = 23 %
Atomic Mass of ¹¹X = 11 amu
Relative Intensity ¹¹X = 100 %
It means that if there are 123 atoms of this mystery element then then 23 will be of an isotope with atomic mass of 10 amu and the remaining 100 will be of an isotope with atomic mass of 11 amu.
So, we will now calculate the total mass of all elements as;
Total Mass = (23 × 10) + (100 × 11)
Total Mass = (230) + (1100)
Total Mass = 1330 amu
Then, we will calculate the average mass as,
Average Atomic Mass = 1330 / 123
Average Atomic Mass = 10.81
Answer: Option (b) is the correct answer.
Explanation:
According to ideal gas law, the product of pressure and volume is equal to the product of number of moles, gas constant and temperature.
Mathematically, PV = nRT
So, when there are two gases with equal number of moles behaving ideally then the ideal gas equation will be as follows.
=
and =
Hence, when temperature and pressure of both the gases will be constant then = 1.
Thus, we can conclude that constant temperature and pressure is the conditions that must be met for a volume ratio to be created from a balanced chemical equation.
The conclusion cannot be validated because other factors such as the amount of sunlight water location also play a vital role in germinate
